Merge, split, encrypt. With FluoLock™ your documents stay yours alone. 15+ tools, no installs, 100% in your browser.
Professional PDF operations without ever leaving your browser.
Make sure your document can only be opened by the person you choose. AES-256-GCM encryption with PBKDF2 brute-force protection.
Tools that upload your files to a server can't offer any of this. Because FluoPDF works in your browser, we can give you control that server-based tools structurally can't.
Send a PDF as a zero-knowledge encrypted link. You decide who opens it, how many times, and for how long — and you can kill access the moment you change your mind.
Black out sensitive info and actually remove it— not a box you can delete later. Most tools (and PDF viewers) leave the hidden text selectable underneath. We don't.
AES-256-GCM encryption done in your browser. Your password never leaves your device.
Core tools run on your device — your files are never uploaded to a server.
Summarize your PDF, ask questions and analyze contracts. (Pro)
Extract text from scanned documents and photos — right in your browser.
Translate your PDF into 17 languages without leaving the page. (Pro)
Merge, compress or convert many PDFs at once and save time. (Pro)
Most online PDF tools upload your documents to a server. FluoPDF doesn't — and that's the whole point.
Core tools — merge, split, compress, rotate, watermark — run entirely on your device. Your files are never uploaded to a server.
FluoLock™ derives the key locally with PBKDF2 (600k iterations). The password is never transmitted — not even to us.
We don't sell your data or follow you around the web. The product is funded by Pro subscriptions, not your privacy.
AES-256-GCM encryption and standard PDF tooling — no proprietary lock-in. Auditable, transparent security.
