Edit PDF — frequently asked questions
- Can I edit existing text in the PDF?
- This tool lets you add new text and annotations on top of the page. To change the underlying text, convert to Word with PDF to Word, edit, then export back to PDF.
- Can I fill out a PDF form with this tool?
- Yes. You can place text over form fields and blanks to complete a document that is not an interactive form.
- Will my annotations be permanent?
- Yes. When you download the file, your added text and notes are embedded into the PDF.
- Is my document uploaded to a server?
- No. Editing happens locally in your browser, so the file never leaves your device.
