Why pdfunli.com exists
Most free PDF sites aren't actually free — they cap how many files you can touch per day, drop a watermark on your output, or quietly upload your documents to a server somewhere before handing them back. pdfunli.com was built to just not do any of that. Most tools here run entirely as JavaScript in your own browser tab, so your files are processed on your device and never sent anywhere; the handful of tools that do need a server (like AI summarizing or translating) only ever send the specific text needed for that one task, never the file itself, and always say so upfront.
It's built and maintained by one person — see the About page for the full story — so new tools get added when there's a genuine gap worth filling, like PDF accessibility remediation or a way to request a specific book. If a tool here doesn't quite do what you need, let us know. Wondering if any of this is actually legit? Read Is PDFUnli.com Legit?
Frequently asked questions
Is pdfunli.com really free?
Yes — every tool listed here is free to use, with no account, no daily limits, and no watermark added to your output. There's no hidden "premium" tier.
Do you store or see my files?
For the great majority of tools, no — the work happens entirely in your browser, and your files never touch a server. A few tools (AI Summarizer, Translate PDF, Auto-Rename, and similar) send only the extracted text needed for that specific task to a text-processing service, never the original file, and always show a consent checkbox before doing so. See the Privacy Policy for the exact breakdown per tool.
Do I need to make an account?
No. Nothing on this site requires signing up or logging in.
Who built this?
pdfunli.com is a solo project — read the story on the About page.
What if the tool I need isn't here?
Reach out and describe what you're trying to do — new tools get added based on real requests like that.
