Edit PDF questions
Which tool do I use to change text in a PDF?
There isn't a single free-text rewriting tool here — PDF Annotator lets you highlight, comment, and draw on top of existing content, and Redact PDF permanently blacks out content you want removed.
Can I combine several edits, like rotating and adding a watermark?
Yes. Run the PDF through one editor, download the result, then open that file in the next editor. Each tool is focused on one job so it stays simple and fast.
Are my files uploaded to a server?
No. Every editor listed here runs entirely in your browser, so your files stay on your device.
