Edit PDF

The PDF Editor is a full canvas-based editing tool for making direct changes to a PDF — adding new content, correcting existing text, or marking up a page — rather than just running one fixed operation like most tools here do. It renders each page onto a canvas you can click and drag on directly, keeps a full undo/redo history of every change, and bakes all of your edits into the final exported PDF when you're done.

The toolset covers the changes people actually need to make to an existing document: Edit Text rewrites text that's already on the page — dashed outlines mark what's editable, and clicking one lets you type over it directly. Add Text drops a new text box anywhere you click. Add Image places a picture or logo that you can then resize from its corner. Shapes adds rectangles, circles, lines, or arrows. Freehand Draw, Highlight and Signature are marked as coming soon in the toolbar; to sign a document today, use the separate Sign PDF tool. An Eraser tool removes anything you've added — layered on top of the PDF, never the PDF's own original content — and Select lets you click back onto anything you've placed to move, resize, or restyle it from the panel on the right.

Every change is tracked as an individual, reversible step, not applied straight into the file as you go. That's what makes the undo/redo history meaningful on a tool with this many different actions available at once — drawing a shape, then rewriting a paragraph, then adding a stamp, can each be undone independently in the order you made them, rather than only being able to discard your entire session and start over. Nothing is written back into the actual PDF content until you export: right up until then, every edit is a layer sitting on top of the original page that you're free to move, resize, restyle, or remove.
