How to use Edit PDF
Upload a PDF and it renders instantly in your browser via PDF.js. Click anywhere to drop a text annotation; drag to highlight a region. All changes are applied server-side by PyMuPDF, producing a proper PDF with embedded annotations — not just an image overlay.

Frequently asked questions
Can I edit existing text in the PDF?+
No — this tool adds new annotations on top of existing content. To replace text, you need a full PDF editor. For converting to an editable format, use our PDF to Word tool.
Are highlights visible in all PDF viewers?+
Yes. Highlights are stored as standard PDF annotation objects (not image overlays) and display correctly in Adobe Acrobat, browsers, and mobile viewers.
How many pages can I edit?+
The editor renders up to 10 pages at a time. For longer documents, annotate in sections and merge the results.
