Frequently asked questions
Is my PDF uploaded to a server?
No. The document and your signature are processed in your browser and are not sent to a server.
Can I upload a photo of my handwritten signature?
Yes. Upload a JPG or PNG of your signature on light paper. Light background pixels are made transparent so only the ink is placed on the page.
Does signing reduce the quality of my PDF?
No. The signature is added on top of the original pages, so the existing text, forms and fine print stay sharp.
Is this a legally binding digital signature?
It adds a visual electronic signature, which many everyday agreements accept. It is not a certificate-based digital signature, so check the requirements if a document asks for one.
Can I sign on my phone?
Yes. You can draw your signature with your finger and place it by tapping the page.
