How to Edit a PDF Online (4 Easy Steps)
Open your PDF
Drop a PDF into the editor or click to browse. The file is loaded in a Web Worker so the page stays responsive.
Annotate pages
Add text, draw freehand, highlight regions, place a signature, or insert an image. Large documents render pages lazily as you scroll.
Rotate or remove pages
Rotate the active page or delete pages you do not need. Only the pages you keep are included in the export.
Download the edited PDF
Click Download to burn annotations into a new PDF with pdf-lib — entirely in your browser, with no server upload.
A Fast, Private Free PDF Editor
Web Worker Processing
PDF loading, canvas rendering, and export run off the main thread so typing, scrolling, and toolbar clicks stay smooth on large files.
Lazy Page Rendering
For multi-page PDFs, IntersectionObserver renders pages as they enter the viewport instead of converting every page to a canvas up front.
100% Private
Your document never leaves the device. Preview uses PDF.js; edits are applied with pdf-lib in local memory.
Text, Draw & Highlight
Overlay editable text, freehand ink, and translucent highlights directly on the page preview before export.
Signatures & Images
Draw a signature or upload a PNG/JPG, then place it on any page. Images are embedded into the final PDF.
No Adobe, No Account
A free PDF editor that works in Chrome, Firefox, Safari, and Edge — no install, no watermark, no email gate.

Free PDF Editor That Runs Entirely in Your Browser
This free PDF editor lets you annotate documents without Adobe Acrobat or an account. Open a file, add text and signatures, then download a new PDF — all locally.
Under the hood, PDF.js renders page previews onto canvas while a dedicated Web Worker keeps loading and export off the main thread. pdf-lib merges your annotations into the downloaded file.
Built for Large Multi-Page PDFs
Instead of converting every page into a canvas immediately, the editor uses IntersectionObserver to render pages as they scroll into view. That keeps memory use lower and scrolling smooth on 50+ page documents.
