About PDF Editor
A full-featured PDF annotation editor that runs entirely in your browser. Add text labels anywhere on a page, draw freehand with a pen tool, highlight regions in multiple colors, and add rectangular boxes or borders. Select and delete any annotation, navigate between pages, and export the final PDF with all your changes embedded as permanent content. Perfect for annotating reports, marking up contracts, providing design feedback, and adding comments to any PDF.
What is PDF Editor?
Sometimes you just need to change something on a PDF — add a note, mark up a page, highlight a clause, or drop in some text — without the whole document being editable in Word. The PDF Editor lets you make those edits directly on the page, so you can annotate, mark and adjust a document and download the result, all in your browser.
Editing happens locally, so the document is never uploaded. You make your changes on the page and download the edited PDF. It is the practical middle ground between viewing a file and fully converting it — quick edits and markups, right where they are needed, with nothing sent to a server.
Key features
Edit directly on the page
Add text, notes and markups straight onto the document where they belong, so you can comment on, correct or annotate a PDF without converting the whole thing to another format.
Annotate and mark up
Highlight a clause, flag a section or add a comment — the kind of review and feedback edits that documents need constantly, done directly on the file.
No full conversion needed
For small changes you do not want to round-trip through Word and back. Editing in place keeps the PDF as a PDF and saves the conversion both ways.
Private editing
All edits are applied on your device, so a confidential document is marked up without being uploaded to any server.

The bottom line
Most PDF edits are small — a note here, a highlight there, a line of text added — and they should not require a heavyweight program or a round trip through Word. The PDF Editor handles those directly on the page, privately and for free, so you can mark up a document and send it back in minutes. For quick changes, it is exactly the right tool.
