FAQ & Help Center

PDFEdit is a collection of tools that run entirely inside your browser tab. When you open a tool such as Compress PDF or Merge PDF, the page loads a client-side component (for example, the compressor is built on the pdf-lib library running in your browser) that reads your file, performs the operation, and produces the result — all on your device.

There are no accounts, no upload queues, and no waiting on a server.

No. Processing is client-side: your documents never leave your device. They are not uploaded to our servers, not stored anywhere, and never viewed by anyone. See our Privacy Policy for details on what data the site does collect (such as advertising and analytics).

Yes — this is exactly what PDFEdit is designed for. Because files never leave your browser, contracts, medical records, and other sensitive documents are not exposed to any third party. On a shared or public computer, just close the tab when you are done and clear your downloads if needed.

Everything is gone. Files live only in your browser tab's memory while you work. Closing the tab or reloading the page discards them — nothing was ever sent to a server, so there is nothing to delete on our side.

Some tools cannot read a password-protected PDF directly. If a tool rejects your file, first remove the password with Unlock PDF (also client-side), then run the tool you wanted. You'll need the file's password.

A few tools enforce their own limits, which are stated in the tool itself:

• Merge PDF: up to 100 MB per file.
• Word to PDF: up to 50 MB per file.

Tools without an enforced limit are constrained only by your device's memory. Very large files on a low-memory phone or tablet may freeze or crash the tab — on a desktop with plenty of RAM, much larger files work fine.

PDF is the core format for every tool. Depending on the tool, other formats are supported:

• Images: JPG, PNG, and WebP can be converted to PDF with Image to PDF and can be produced from PDFs with PDF to JPG.
• Word: PDF to Word produces .docx files, and Word to PDF accepts .docx input. Legacy .doc files are not supported — save or re-export them as .docx first.
• PDF to Text extracts plain text from PDFs.
• Sign PDF and PDF Studio work with PDF documents directly.

Yes. The tools work in modern mobile browsers on phones and tablets, as well as on desktop. Large or complex files process more smoothly on a desktop, so for very big documents we recommend using a computer.

Any modern, up-to-date browser with JavaScript enabled — on desktop or mobile. The tools rely on current web APIs for file reading, in-browser PDF processing, and downloads, so keeping your browser updated gives the best results.

No. Everything runs in the browser — nothing to install, and no account or sign-up is required to use any tool. Open the tools page and start working.

Yes, the tools are free to use, with no watermark on core tools and no sign-up. See our Terms of Service for the rules of use.

Work through this checklist:

1. Confirm the file is the format the tool expects (e.g. .docx, not .doc, for Word to PDF).
2. Check the file is not empty (0 bytes) or corrupted — try opening it in another app.
3. If the PDF is password-protected, unlock it first with Unlock PDF.
4. Try a smaller file, in case you hit a size limit or memory ceiling.
5. Update your browser to the latest version and try again in a private/incognito window (this rules out extensions interfering).

The tool ran out of your device's available memory. Close other tabs and apps, then try a smaller file — or move to a desktop computer, which typically has far more RAM than a phone. If one specific tool always fails, tell us about it via the contact page with the tool name, browser, and file size.

Compression works by removing redundancy. If the PDF was already optimized, or its bulk is high-resolution scanned images, Compress PDF may only shave off a little. Try a different compression profile in the tool, or reduce image-heavy pages before compressing.

This usually means the PDF stores text as scanned images rather than real text — there are no characters to extract. For scanned documents, use OCR PDF to recognize the text from the images first.

Reach out through the contact page — include the tool you were using, your browser and device, and the exact error or behavior you saw. The more detail you give, the faster we can help.
