Frequently Asked Questions — PDF Editing

Can I edit existing text in a PDF document?

Our editor allows you to overlay new text, annotations, and redactions over any page area. While it does not support deleting underlying original embedded text blocks directly, you can easily use the redact tool to mask them and write over them.

How are annotations saved?

When you export the edited document, all overlay texts, shapes, signatures, and stamps are compiled and written directly into the PDF structure, ensuring they render correctly in any standardized viewer.

Does this support PDF signing compliance?

Yes, visual signatures and image stamps added locally are fully embedded. For legally binding electronic signatures requiring cryptographic certificates, we recommend standard enterprise signing services.
