Most online PDF tools upload your file to a server. PDF Ultra Pro doesn't have one.
Nothing leaves your device
Every tool runs with JavaScript in your browser tab. There's no upload step because there's no server to upload to.
Even OCR runs on-device
Scanned PDFs get a real, searchable text layer using an in-browser OCR engine — in 8 languages, no server round-trip.
Drag, drop, done
Reorder pages, batch-upload files and preview thumbnails with a UI built for quick edits.
Works offline once loaded
Installable as an app — open PDF Ultra Pro without a connection after your first visit.
No account, no watermark
No sign-up walls, no forced watermarks on your output, no artificial daily limits.
Honest about limits
Where a tool can't be done safely in the browser (like real PDF encryption), we say so instead of faking it.
Frequently asked questions
Is my file actually uploaded anywhere?
No. Every tool on this site uses JavaScript libraries (pdf-lib, pdf.js, and a few others) that run inside your browser tab. Files are read with the File API and processed locally — this site doesn't have a backend to upload to.
Is PDF Ultra Pro really free?
Yes. The tools are designed to run in your browser without a paid account.
Why don't Protect PDF and Unlock PDF work yet?
Real password encryption and password removal require capabilities that aren't safely available in this browser-only implementation.
How accurate is OCR PDF?
OCR accuracy depends heavily on scan quality, language, resolution and document layout.
Does this work on mobile?
Yes. PDF Ultra Pro is designed to work in modern mobile browsers, although large PDFs can require more memory and processing time.
