Yes, you can edit a signed PDF, but it will likely invalidate the signature. To make changes, use a PDF editor and be aware that you'll need to re-sign the document to ensure its authenticity. If edits are minor and don't need a complete re-sign, consider using the 'Add Comment' feature available in many PDF readers for annotations.
