Why client-side
- No file-upload endpoint. There is no file-processing backend or file-upload endpoint. Document processing happens in this tab, so BrowserPDF cannot receive or store the files you open.
- Verified libraries. The open-source libraries each tool relies on are fetched, checked against a pinned cryptographic hash, and only then executed. A tampered download is rejected, not silently run.
- No account; analytics storage is optional. No signup. Analytics storage remains denied unless you accept it, and BrowserPDF provides no file-upload endpoint to analytics. Our host still receives ordinary web requests and aggregate traffic data.
- Completely free, no watermarks. Every tool is fully functional, with no watermark added to your files and no service-imposed page or usage limits beyond what your browser can handle.
Frequently asked questions
Is BrowserPDF really free?
Yes. Every tool is fully functional with no account, no premium tier, no added watermarks, and no service-imposed usage limits.
Are my files uploaded anywhere?
No. Each tool processes your document inside the browser tab using JavaScript and WebAssembly, and BrowserPDF has no file-upload endpoint. You can verify this in your browser's network panel.
Is there a file size limit?
We don't impose one. The practical limit is your device's memory, since all processing happens locally. Very large files simply take longer on slower hardware.
Do scanned PDFs work?
Yes. Tools that read text (PDF to Markdown, PDF to Word, Extract Text, Make Searchable) fall back to OCR that runs on your device, with 14 selectable languages.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari, on desktop and mobile. Older browsers without WebAssembly support won't run the OCR-based tools.
How can I trust this?
BrowserPDF's application code is source-available. Its open-source libraries are pinned to exact versions and verified with a cryptographic hash before they run, and you can inspect the browser network panel to verify that selecting a document makes no file-upload request.
