Most PDF editors require a desktop installation or a paid subscription. This tool runs entirely in your browser using PDF.js — the same technology trusted by Firefox and Google Chrome. There's nothing to install, and it works on Windows, Mac, Linux, iOS, and Android.
All annotation rendering happens client-side using HTML5 Canvas, so performance is fast and your document stays completely private. Your PDF is never uploaded to any external server or cloud service.
Students can annotate research papers, highlight key passages, and add study notes directly to lecture slides or textbooks.
Professionals can mark up contracts, add signatures, insert comments, and return documents — without needing Adobe Acrobat.
Teachers can annotate student submissions, add feedback with sticky notes, and highlight sections for review.
Anyone who needs to quickly fill in or annotate a PDF without subscribing to a service will find this tool instant and friction-free.
Yes — completely free, with no freemium limits. You don't need to create an account, verify an email, or enter payment details. There are no daily download caps, no page limits, and no watermarks stamped on your exported files.
UsedToTools is built around the philosophy that essential productivity tools should be accessible to everyone, free of charge.
Your files are processed entirely within your own browser. When you open a PDF, it is read by the JavaScript engine on your device and rendered to an HTML5 canvas — no bytes are transmitted to any external server.
This makes the editor ideal for sensitive documents: contracts, medical records, financial statements, or personal files you would never want to upload to a cloud service.
