Start to finish in under a minute

1

Drop your PDF

Drag a file onto the page or click “Launch App.” It stays in your browser — we literally cannot see it.

2

Use the tools

Summarize, redact PII, sign, extract tables, highlight, annotate. Everything runs client-side.

3

Export & done

Download your edited PDF, export annotations, or save to your encrypted local collection.

Not a promise — a technical constraint

Most “private” PDF tools still upload your files to a server. PrivDF can’t do that even if we wanted to — the code never sends your document over the network. AI queries go to Venice.ai with extracted text only, never the file itself.

No server uploads

PDFs never leave your browser. Zero network requests with your files.

Client-side encryption

Annotations encrypted with AES-GCM before hitting IndexedDB.

Auditable & open source

Every line of code is public. Verify our privacy claims yourself.

Ready when you are
