PDF processing boundaries
These tools operate within browser memory and the capabilities of the browser PDF libraries used on this page. Encrypted, malformed, scanned, XFA, unusual forms, complex signatures, OCR-dependent documents, and advanced desktop-editor features can require specialist software. Always verify generated files before discarding the source.
How to use this PDF Editor
Choose a PDF, move between pages, and work directly on the rendered preview. Text and image tools place an overlay where you click; highlight, rectangle, whiteout, and freehand tools use drag gestures. You can undo page marks, clear one page, reorder output pages, rotate the final document, and export a new PDF.
