The PDF toolkit that never sees your files
AI summaries, PII redaction, digital signatures, table extraction — all running in your browser. Nothing is uploaded. Ever.
AI Summarize & Q&A AI
Ask questions about any PDF. Get answers with page citations.
PII Redaction Privacy
Auto-detect and black out SSNs, addresses, phone numbers.
Digital Signatures Security
Sign PDFs with X.509 certificates. Generate certs in-browser.
Table & Chart Extraction Data
Pull tables to CSV. Extract data points from XY charts.
Edit & Annotate Tools
Highlight, underline, strikethrough, fill forms, add text.
Encrypted Storage Local
AES-GCM encryption. Notes unreadable without your password.
Three steps, no sign-up
Start to finish in under a minute
Drop your PDF
Drag a file onto the page or click “Launch App.” It stays in your browser — we literally cannot see it.
Use the tools
Summarize, redact PII, sign, extract tables, highlight, annotate. Everything runs client-side.
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
No install, no account, no data collection. Just open a PDF.
