Sign PDF — Frequently Asked Questions
Is this a cryptographic signature?
No. This adds a visual/handwritten signature to a PDF — the same flow as signing a paper document. For cryptographic signatures (digital certificates, PKI), you'll need a dedicated signing tool.
Can the signature be removed after I save?
By default, signatures stay as annotations and can be moved or deleted. Toggle 'Flatten on save' to bake the signature into the page permanently.
Which signature format should I pick?
Draw feels most authentic if you have a trackpad or tablet. Type is fastest — pick a handwriting font. Upload is best if you already have a scanned signature image.
Does this upload my PDF anywhere?
No. Your PDF and signature never leave your browser.
