Frequently asked questions

Everything you need to know about PDFCrush. Can't find an answer? Get in touch.

General

Is PDFCrush completely free to use without hidden usage caps?

Yes. Every document utility on PDFCrush is completely free with no premium paywalls, forced watermarks, daily conversion thresholds, or mandatory account registration rules.

What is the maximum file size I can process inside a tool session?

100MB is the maximum individual file size supported per upload slot. You can process as many consecutive 100MB files as your hardware allows without speed throttling.

What happens if my internet connection drops during file compilation?

All tools continue processing completely uninterrupted because our core layout engines run entirely offline using local client-side WebAssembly execution scripts within your isolated browser tab.

Are my uploaded proprietary files stored on PDFCrush servers?

No. Your documents are never uploaded to a remote server. Processing happens entirely within your web browser's temporary sandbox memory and vanishes cleanly the instant you close the tab.

Do I need to sign up or create a profile to use premium tools?

No. Registration is never required on this platform. You can access advanced extraction, encryption, and editing modules immediately without providing an email address or inputting card numbers.

Which specific web browsers and operating systems are supported?

All modern browsers - including Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge - are fully supported across Windows, macOS, Linux, iOS, and Android system frameworks natively.

How does PDFCrush monetize the platform if everything is free?

We fund our site infrastructure through non-intrusive, privacy-safe display advertisements. Because our serverless layout model shifts all parsing tasks to your browser, we have no massive server hosting costs per execution.

Can I use these document management utilities entirely offline?

Yes. Once the webpage loads its local asset dependencies online, you can pull your network cable or toggle airplane mode. The local compilation runtime executes completely isolated within your machine's boundary.

Compress PDF

Will compressing a PDF make the text blurry or unreadable?

No. Our compression profiles target unneeded structural metadata and downsample oversized background graphics down to web-standard limits 150 DPI while leaving underlying vector text perfectly untouched.

How much file size can I reduce from a PDF?

You can typically reduce file footprints by 30% to 85% on the source content layout. High-resolution graphics compress deeply, while plain text layout structures see minimal changes.

Can you compress a password protected PDF document?

Yes, provided you enter the valid master owner password. The browser engine uses local decryption routines to unlock the stream, apply compression parameters, and save the file.

Will text remain selectable after running the PDF compressor?

Yes. Unlike crude tools that rasterize pages into flat images, our engine optimizes resources natively, keeping all underlying vector text fully searchable and selectable via Ctrl+F.

Is there a maximum starting file size constraint for local browser compression?

There is no rigid software barrier, but since compression calculations occur in local browser memory threads, documents larger than 100MB may encounter performance thresholds on older computers.

What image compression techniques are applied to background graphics?

The compressor optimizes files by stripping unneeded color maps, clearing metadata markers, and applying lossless or high-efficiency compression parameters directly to image elements.

Why didn't my text heavy layout document show a major reduction in file size?

Text matrices and vector elements are already highly efficient data structures. Significant file size reduction occurs on documents containing high-resolution image assets.

Is my proprietary data secure when processing corporate documents?

Completely. Because the optimization tasks run locally inside your browser sandbox, your files never upload to an external server, keeping your workflow compliant with data-handling policies.

PDF Scanner

Can I use my mobile device camera as a live document scanner?

Yes. The live camera scanner interface accesses your mobile hardware view directly inside the webpage tab, creating clean vector PDF output sheets with zero app installations.

How many separate paper pages can I snapshot into a single file scan?

There are no arbitrary page limitations. You can execute multiple frame captures sequentially, manage execution paths via touch thumbnails, and instantly pack the sequence into a unified PDF.

Does the virtual document scanner fix warped boundaries or angled perspectives?

Yes. The automated deskew engine detects paper matrix margins dynamically, applying real-time perspective matrices to straighten geometric curves and clear text reading flows perfectly.

Are my proprietary office documents secure from server side tracing logs?

Yes. Every document capture routine runs entirely inside your browser tab using fast client-side JavaScript APIs. Your personal receipt pictures and data blocks are completely secure.

Can I swap filters to save documents in high-contrast black and white?

Yes. The interface features filter toggles, letting you choose between full color, gray scale, or high-contrast monochrome outputs to maximize readability.

What happens if a background element gets captured inside my document scan?

You can manually adjust the four corner handles after capturing an image to crop out table surfaces or backgrounds cleanly.

Can I import a pre-shot camera roll photo instead of using the live capture?

Yes. The interface supports direct image uploads (JPG, PNG, WEBP), running the same deskew and enhancement tools on your pre-shot photos.

Will the resulting scanned pages carry searchable text data strings automatically?

No. The scanner tool outputs optimized image pages wrapped inside a PDF container. To make the text searchable, process the output file through our **OCR PDF** tool.

Merge PDF

Will combining multiple PDFs reduce the quality of my document text?

No. Merging appends your pages together natively by copying their structural index nodes directly. Your underlying text baselines, embedded typography tables, and coordinate vectors remain completely unaltered.

How many separate PDF files can I merge at once for free?

You can merge up to 20 separate PDF files simultaneously into a single file in a single batch sequence without hitting paywalls or account pop-ups.

Can I combine PDF documents that contain different page orientations?

Yes. Each page preserves its independent layout box model A4, Letter, Legal) and visual orientation flags (portrait or landscape) natively inside the newly consolidated output file tree.

Are my files uploaded to cloud storage buckets during the merge process?

No. The compilation thread executes locally inside your web browser using sandboxed memory arrays. Your files never cross an external network interface throughout the operation.

Can I drag and drop thumbnails to change the page order before merging?

Yes. The canvas dashboard features an interactive drag-and-drop array structure, allowing you to reorder, shift, or preview individual file segments visually before clicking merge.

What happens if I try to merge files that have existing password restrictions?

Locked files cannot be merged directly because encryption blocks the page table index. You must first strip owner-level security settings using our **Unlock PDF** tool before running a merge batch.

Does merging separate files cause internal table of contents hyperlinks to break?

No. Outbound hyperlinked web URLs and local page link vectors remain active, though relative page indicators will offset automatically to align with their new position in the compiled layout.

How large can the finalized combined output document be?

The consolidated output file can contain hundreds of pages, provided your browser's allocated memory pool can build the final blob. We recommend limiting total cumulative input to under 200MB for optimal mobile rendering.

Split PDF

Will splitting a PDF cause layout formatting or font tracking loss?

No. Splitting extracts your pages cleanly by duplicating the original cross-reference structural tables. All page elements - including vector paths, embedded asset layers, and font links - survive the separation intact.

Is there a limit on how many pages I can extract from a file?

No. You can split documents of any page length up to our maximum 100MB file system capacity without incurring service costs or running into hidden page block restrictions.

Can I split an encrypted or password locked PDF file?

Only if you provide the correct owner password. The tool decrypts the PDF locally in your browser using local decryption arrays before mapping out the separate file blocks.

Are my individual document slices safe from remote cloud storage storage?

Yes. Every extraction operation occurs natively inside your client-side browser tab using local sandboxed memory arrays. Your source file and output slices are never cached across an external database.

How do I extract a custom discontinuous range of separate pages?

You can input custom comma-separated range sequences (such as '1-3, 7, 14-19') into the range picker box to instantly isolate and download specific separate page groups.

Can I automatically divide a large document into equal page chunks?

Yes. The splitting control includes an equal division macro (e.g., entering '5' into a 50-page document automatically splits it into ten distinct 5-page PDF blocks instantly).

What happens to a document's historical digital signatures when it is split?

The pages separate successfully, but splitting inherently invalidates the cryptographic validation hash of the original document, removing original certificates to preserve digital compliance.

Can I extract a single specific page and save it as a standalone file?

Yes. Simply input a single numerical index value (such as '12') into the extraction parameter field to cleanly isolate that standalone sheet into a fresh PDF file container.

Rotate PDF

Will permanently rotating PDF pages degrade embedded graphic resolutions?

No. This tool rewrites the page geometry transformation flag matrix /Rotate) inside the document's dictionary structure. It changes display rules without re-encoding or compressing layout data.

Can I rotate specific individual pages inside a multi page document?

Yes. The responsive dashboard layout displays clear visual thumbnails for every page block, allowing you to highlight and rotate standalone pages by 90 ext{°}, 180 ext{°}, or 270 ext{°} independently.

Does rotating a page mess up text selection highlighting tools?

No. Because our structural engine changes the orientation mapping parameters, your text font coordinates shift in alignment with the visual rotation, keeping text selections accurate.

Is it safe to rotate confidential financial data layouts here?

Yes. The structural rotation calculations execute locally in your active browser session. No data is cached or routed through cloud databases.

Can I batch rotate every single page in a document with one click?

Yes. The primary toolbar features global adjustment triggers ('Rotate All Left' and 'Rotate All Right') to apply uniform landscape or portrait corrections across all sheets instantly.

Does this orientation tool work on high resolution scanned blue prints?

Yes. The rotation logic modifies container display parameters directly, making it highly efficient for complex blueprints and multi-megapixel map layers.

Will applying rotation changes increase my overall document file size?

No. Since the operation updates small page orientation parameters without adding text boxes or graphics, the output file footprint remains virtually identical.

Can I undo my rotational changes if I flip the wrong page layout?

Yes. You can toggle page controls back and forth, or use the 'Reset All' modifier in the workspace to discard changes and revert to the original orientation configuration.

Remove Pages

Will deleting specific unneeded pages shift the remaining layout flow?

No. PDF pages are distinct absolute object containers. Removing a page node cleans it from the root dictionary tree without altering margins or text positions on adjacent pages.

Can I remove bulk groups of pages from a document?

Yes. You can use our quick-select options to instantly clear all odd pages, even pages, or manually select a custom array of layout thumbnails to purge instantly.

What happens to document hyperlinks when target pages are deleted?

Outbound hyperlinked web URLs remain fully active, while internal page links pointing directly to deleted pages will become inert.

Are deleted sheets permanently removed without a recovery trail?

Yes. The deletion logic clears the target page reference from memory arrays entirely before output generation, leaving zero recovery trails behind.

Is there a restriction on how many pages I can strip out of a single file?

No. You can drop a single blank sheet or purge up to 99% of a document's overall footprint, provided at least one core page frame remains to form a valid PDF container structure.

Can I preview thumbnails of each page before confirming deletion?

Yes. The application builds clear local rendering snapshots of every page layer in the view tray, letting you confirm content layout before dropping specific sections.

Does dropping unneeded pages automatically reduce the output file size?

Yes. Dropping sheets completely eliminates their coordinate arrays and localized image references, dropping the overall file footprint cleanly.

Can I process private medical or legal records securely through this page remover?

Yes. Because the deletion algorithms run inside local sandboxed browser scripts, your confidential data is never exposed to remote network environments.

Extract Pages

Does extracting a specific chapter degrade the crisp clarity of text strings?

No. Extraction reads your desired page indices and clones their exact raw vector object content blocks. Your specialized formatting styles and embedded asset layers carry forward with zero degradation.

Can I extract non consecutive page patterns from multiple sections?

Yes. The graphical user interface allows you to click separate page fragments across the entire document layout. You can pull an isolated mix of random sheets and compile them into a unified continuous output file.

Will interactive elements continue to function on extracted pages?

Yes. Interactive form components and interactive data attributes carry over to your new isolated PDF file, provided the parent form schema properties are directly tied to that local page stream object.

Is my personal data protected when extracting medical or legal records?

Yes. The parsing calculations utilize local sandboxed memory arrays exclusively via your local browser environment. No telemetry data or document data packets are transmitted outside your local instance.

What is the primary difference between extracting pages and splitting a document?

Splitting divides an entire file sequentially based on custom ranges, whereas extraction lets you select specific pages out of order and merge them into a new file container.

Can I change the position order of extracted thumbnails before downloading?

Pages are compiled based on their native document index sequence. If you need to reorder the extracted sheets, simply drop the output file into our **Merge PDF** tool to arrange pages freely.

Can I extract pages from multiple uploaded PDF documents simultaneously?

No. The interface processes one document file tree per session to maintain system speed. You can easily merge separate extracted outputs using our merge board later.

Does page extraction work cleanly when executed inside mobile web browsers?

Yes. The thumbnail selector layout is touch-optimized and responsive, making it easy to select and extract pages on mobile devices.

Add Page Numbers

Will overlaying page numbers conflict with my document's text flow?

No. Page number indicators are stamps drawn onto an independent canvas layer over your existing layout elements. Your existing paragraphs, margins, and underlying structural elements remain completely unchanged.

Can I adjust the placement styling coordinates and font configuration?

Yes. You can customize position variables (such as headers or footers across left, center, or right planes), change numeric string formatting (like 'Page X' or 'X of Y'), and set custom text size offsets.

Can I skip rendering page numbers on the title page?

Yes. You can configure a specific starting index offset parameter to tell the script runner to skip formatting rules on page one, letting your number sequence begin cleanly on page two or later.

Does stamping page numbers require server processing?

No. The vector text rendering pipeline dynamically overlays string metrics locally using client-side JavaScript. Your sensitive data profiles remain entirely isolated from any remote access risk.

What font options are used to render added page number strings?

The rendering system uses clean standard typography families optimized for global system compatibility, ensuring text metrics scale cleanly without requiring heavy custom asset downloads.

Can I control the precise digital string format for numeric listings?

Yes. The interface lets you choose between simple integers ('3'), structured strings ('Page 3'), or relational fractional blocks ('Page 3 of 24') instantly.

Will adding page numbers alter historical metadata fields within the document wrapper?

No. The core tool leaves original metadata fields like Author, Creation Date, and structural parameters intact while appending the formatting changes.

Does page numbering work correctly on scanned document page canvases?

Yes. The layout engine places the new string layers cleanly over flat scanned images or native digital vectors alike, ensuring readability across all page styles.

Edit PDF

Can I rewrite existing embedded PDF paragraphs directly with this browser tool?

No. Rather than rewriting core compiled text streams, this browser tool functions as an annotation layer. It lets you add new text layers, draw shapes, mask items, and layer markup elements onto your document canvas cleanly.

Is there a cap on how many annotations or shape structures I can draw?

No. You can add text boxes, highlight arrays, and use vector drawing elements freely. The local client script handles tracking coordinates on the fly without causing slow download lag.

Will custom text additions render correctly in standard external PDF readers?

Yes. All added markup layers are saved back down into standardized, universally compatible PDF annotation schemas, ensuring they render correctly when viewed in external software like Adobe Acrobat or Apple Preview.
