Questions People Ask

Honest answers about how this works.

Are my annotations saved permanently?

Yes, when you export the PDF, all annotations are permanently embedded into the new PDF file as rendered content.

Is the PDF uploaded to a server?

Great question. No. Everything runs locally in your browser using pdfjs-dist for rendering and pdf-lib for export.

Can I really edit existing text in the PDF?

Short answer: PDF Editor currently supports adding new annotations (text, highlights, drawings) on top of pages. Editing existing text content is not supported.
