Edit PDF

How to edit a PDF

1. Open your PDF. Drop a PDF into the box above. Every page is rendered with a thumbnail sidebar for quick navigation.
2. Pick a tool. Text, pen, highlighter, shapes, lines, whiteout, image, or signature — choose from the toolbar and work directly on the page.
3. Arrange your edits. Switch to the arrow tool to move, resize, recolor, or delete any element. Undo and redo work as expected (Ctrl/Cmd+Z).
4. Export. Click Export PDF — your edits are burned into a copy of the document, and the original stays untouched.

What you can do with this editor

• Fill in forms and add text — click anywhere, type, choose size and color. Multi-line text is supported.
• Sign documents — draw your signature with mouse, trackpad, or finger, then place and resize it on the page.
• Highlight and annotate — a marker for text passages, a pen for freehand notes, plus rectangles, ellipses, and lines for clean markup.
• Cover content with whiteout — place white boxes over parts you want hidden in the copy you share, then write corrections on top.
• Insert images — stamps, logos, or a photo of your handwritten signature (JPG/PNG).

Private by design — even for signatures

PDF editing is the most privacy-sensitive PDF task there is: the documents involved are contracts, application forms, medical paperwork — and your signature itself is personal data. This editor runs completely in your browser. The document, your edits, and your drawn signature are never transmitted anywhere; you can disconnect from the internet after the page loads and keep working.

When you export, the edits are permanently drawn into a new copy of the PDF on your device. The original file is never modified, so you can always start over.

Good to know

• Text you add is real, selectable PDF text (Helvetica). The rest of the document keeps its original quality — nothing is re-rendered or recompressed on export.
• Editing text that already exists in the PDF isn't directly possible in any browser editor — the practical approach is whiteout over the old text plus a new text box. That's exactly what the whiteout tool is for.
• A note on whiteout: it visually covers content in the flattened export, but for legally sensitive redaction (e.g. publishing documents), use a dedicated redaction tool that removes the underlying data.
• Password-protected PDFs must be unlocked before editing.
