How to Edit a PDF Online (4 Easy Steps)

Drop a PDF into the editor or click to browse. The file is loaded in a Web Worker so the page stays responsive.

02
✍️

Annotate pages

Add text, draw freehand, highlight regions, place a signature, or insert an image. Large documents render pages lazily as you scroll.

03
🔄

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.

04
📥

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.

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.
