Frequently Asked Questions
Is this PDF editor really free? +
Yes, completely free. No hidden charges, no subscription, no sign-up required.
Are my PDF files safe and private? +
Absolutely. Everything runs 100% in your browser. Your files never leave your device — no server uploads, no third-party access. Your documents are completely private.
Can I edit the original text in a PDF? +
This tool adds annotations on top of the existing PDF content. To change original text, use the Add Text tool to cover or replace it, or use the Redact tool to black it out and add new text on top.
Will my edits be saved permanently in the PDF? +
Yes. When you click "Download Edited PDF", all annotations — text, drawings, shapes, highlights, and redactions — are permanently embedded into the PDF file.
Can I undo changes? +
Yes — use the Undo button in the toolbar or press Ctrl+Z / Cmd+Z to undo the last annotation. You can also click the delete button (✕) next to any annotation in the annotation list.
How does the redaction tool work? +
Draw a black rectangle over the content you want to hide using the Redact tool. When you download the PDF, that area is covered with a solid black box — the underlying content is visually hidden but the original PDF data remains (this is a visual redaction, not a cryptographic one).
Do I need to install any software? +
No installation needed. Works entirely in your web browser on any device — Windows, Mac, Linux, Android, and iOS.
Does it work on mobile? +
Yes! The tool is fully responsive and works on any mobile browser. Touch drawing is supported for freehand and shape tools.
