Open →Frequently Asked Questions
Can I add a handwritten signature to a PDF?
Yes. The Sign PDF tool lets you draw a signature with a mouse or stylus, type it as text, or upload a signature image — and place it anywhere on the document.
Is the watermark embedded in the file or kept as a separate layer?
The watermark is rendered directly into the PDF page and cannot be easily removed without specialized tools.
Can I add page numbers to an existing PDF?
Yes. The Page Numbers tool lets you choose position (top, bottom, center or corner), numbering format, and starting number.
Is it possible to edit existing text in a PDF?
Basic text editing is available. For significant layout changes, converting to Word and back typically gives better results.
Can I permanently redact sensitive information from a PDF?
Yes. The Find and Redact tool lets you permanently black out selected text so it cannot be recovered.
