Frequently asked questions
Does this signature have legal weight?
Electronic signatures created here are a visual representation embedded in the PDF. For most everyday purposes — contracts, forms, agreements — they are widely accepted. For regulated industries requiring certified eSignatures, a platform like DocuSign may be needed.
Can I fill in form fields?
Yes. The tool detects AcroForm fields automatically and lets you type into text fields, check checkboxes, and select radio buttons.
Is my signature saved anywhere?
No. Your signature is processed in your browser and embedded only in the PDF you download. Nothing is stored, saved, or transmitted.
Are my files private?
Yes. Signing and form filling happen entirely in your browser. Your document never leaves your device at any point.
Can I sign a password-protected PDF?
If the PDF requires a password to open, use Unlock PDF first to remove the restriction, then sign it.
