Free Online PDF Editor — Add Text & Highlights
Make quick visual edits to any PDF without installing desktop software. Upload a PDF, see the first page as a live preview, click to add text labels, draw highlight boxes over important sections, then export a clean edited PDF — all in your browser, completely free and private.

Frequently Asked Questions
Can this editor change the original text inside the PDF?
The tool overlays new text and highlights on top of the page. It does not delete or rewrite existing embedded text — the original content remains underneath.
Can I edit more than the first page?
Currently the editor renders and exports edits onto the first page. Multi-page editing can be added by extending the UI to paginate per-page overlays.
Can I sign a PDF with this tool?
You can approximate a typed signature by adding a text box. For a proper signature feature, image stamps or freehand drawing would be the next step.
Why do my highlights look slightly different after export?
The preview uses CSS transparency while the exported PDF uses pdf-lib opacity values. They should be close, but exact appearance can vary between PDF viewers.
Is this safe for sensitive documents?
The rendering and editing is done in your browser using client-side code. Files processed locally never leave your device during the editing session.
