Frequently asked questions

PaperWorksPDF is built around local browser processing for the PDF tools in this app. Your selected files are opened by your browser so the tool can process and download the result.

Do not close or refresh the tab while a large file is processing, because the browser holds the current work in memory.

Large scanned PDFs, high-resolution image pages, hundreds of pages, older mobile devices and low available memory can all affect preview speed.

For smoother editing, close unused tabs, use a modern browser, work with one large file at a time and let page previews finish rendering before rapid zooming or scrolling.

Some PDFs contain real selectable text, while others are only page images from a scanner. Text extraction works best when the document has a text layer.

For scanned documents, use OCR first, then search or convert the generated text output.

Yes. The Password protect tool encrypts a PDF with the password you provide. Keep that password somewhere safe, because PaperWorksPDF cannot recover a password you forget.

Some browsers may block downloads or show warnings for encrypted files until you confirm the download.

There is no fixed server limit because processing happens in your browser. The practical limit is your device memory, so a desktop browser handles very large files far better than an older phone.

If a huge file struggles, split it into smaller parts first, run the tool on each part, then merge the results.

No. Every PDF and text tool on the dashboard works without signing up, and there is no watermark added to your output files.

An account is only relevant for shared signature requests, where a link needs to stay reachable for the other person.

Open the share tool, upload the document, and generate a signing link for your recipient. They open the link in any browser, place their signature and submit it.

You can follow progress from the tracking page and download the signed copy once it is completed.

Yes. The editor detects the text on a page and matches font size, style and position when you retype it, so replacements blend into the original layout.

Text stored as a scanned image cannot be edited directly — run OCR first, or cover the area with the erase tool and add new text on top.

The interface, page previews and most tools are fully responsive and work on modern mobile browsers.

Heavy jobs such as compressing a large scanned file or editing a document with hundreds of pages are noticeably faster on a laptop or desktop.

Recent versions of Chrome, Edge, Firefox, Safari and Brave are supported. Keeping your browser updated gives the best rendering and download behavior.

Private or hardened browsing modes sometimes restrict downloads and memory, which can make large files fail where a normal window succeeds.

Browsers sometimes warn about files generated in the page, especially encrypted PDFs. Confirm the download when prompted, or check your browser's download settings for this site.

Downloads are served as regular files with a proper filename, so allowing them once is usually enough.

Use the navigation or dashboard links for supported tools and pages. If you manually type a URL or open an old link, it may point to a route that no longer exists.

PaperWorksPDF includes public About, FAQ, Security, Contact, Privacy Policy and Terms routes so standard site links resolve correctly.

Head to the contact page and describe the tool, the browser and the exact step that failed. Screenshots of the error state help a lot.

Please avoid attaching confidential documents in a first message — a redacted sample is enough to reproduce most issues.
