A toolkit that lives in a tab, not an install

Beyond conversion, PrivaPDF's browser-based approach extends to the full toolkit — merging, splitting, compressing, signing, locking, and unlocking all run as WebAssembly modules inside the same page, so switching between tasks doesn't mean switching apps or re-uploading a file to a different service.

Because everything is just a web page, the toolkit works identically across operating systems — the same tab behaves the same way on Windows, macOS, ChromeOS, or Linux, with no platform-specific installer to maintain.

Don't trust us.
Verify it yourself.

Open DevTools → Network while converting. You'll see zero outbound requests. Every byte stays inside your browser tab.

Common questions

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.

What PDF tools are available?

Convert (Word, Excel, PPTX, TXT, Markdown, HTML), Compress, Merge, Sign, Encrypt, and more. All run locally in your browser.

Does this work offline?

Yes. Once the page is loaded, you can disconnect from the internet and the tool will still work perfectly.

Is it really free?

Yes. You get 5 free tool uses per day. No account or credit card required.
