About Add a Signature to a PDF
Draw a signature or upload a photo. Remove the background, then place it on your PDF.
How it works
- Upload your PDF.
- Draw a signature or upload a photo. Crop the signature and preview its transparent background.
- Choose Use signature, place it on the page, and download the signed PDF.
Before you download
Draw or upload a photo of dark ink on light paper. Photo backgrounds are removed in your browser; select the signature area to exclude other writing. This adds a visual signature, not a certificate-based digital signature.
Common questions
Can I use a signature photographed on my phone?
Yes. Upload a clear photo of dark ink on light paper, crop to the signature and inspect the background-removal preview.
Is this a certificate-based digital signature?
No. It places a visual signature mark. It does not provide a certificate identity, cryptographic signing or a signing audit trail.
Can I put a handwritten signature photo into a PDF?
Yes. Upload a clear image of dark ink on light paper, select the signature region and inspect background cleanup before placing it. Use a transparent signature image when you need the page underneath to remain visible.
