PDF Editor — FAQ

Can I add a signature to a PDF?

Yes. Use the freehand drawing tool to draw your signature directly on the PDF. Alternatively, type your name in a signature-style font using the text tool. Download the signed PDF which will contain the signature as a permanent annotation on the document.

Can I edit the existing text in a PDF?

This tool adds annotations on top of existing PDF content — it does not allow editing the original text already in the PDF. To change existing text, you would need a full PDF editing suite. For adding new text, notes, and visual markups, this annotation tool covers all common review and signing use cases.

Will annotations be visible in other PDF readers?

Yes. Annotations are flattened and baked into the PDF as image-based overlays before download. This means they are visible in all PDF readers (Adobe Acrobat, Preview, Chrome PDF viewer, etc.) without needing special annotation support.
