Replace existing text, add new text, draw shapes and freehand lines, highlight, and place images on any PDF — all processed locally in your browser, with scanned pages recognised automatically.

Bake a filled form's values into the page so the PDF can't be re-filled or edited, entirely in your browser with no upload.

Run OCR on a scanned PDF entirely in your browser to add an invisible text layer, so the pages stay pixel-identical but become selectable and searchable in any PDF reader.
