Frequently asked questions
Is this a legally binding electronic signature?
Sign PDF places an image of your signature, drawn or uploaded, on the page. It is not a certificate-based digital signature. Check first whether the recipient accepts a signature image, and for contracts that must be legally binding, use a certified e-signature service.
Can I sign several pages?
Yes. In Sign PDF, enter pages such as 1, 3-5 under Pages to sign, and the same signature is placed on page 1 and pages 3 to 5 at the same position and size. You can also click pages in the preview to select them.
Can I use a photo of my handwritten signature?
Yes. In Sign PDF, click “Upload image” and choose a PNG or JPG. A PNG with a transparent background looks most natural. A photo of white paper brings its background along, so crop it tightly around the signature first.
Is it free?
Yes. Use it free in your web browser, with no sign-up or software to install.
Are my files stored on a server?
No. This tool runs inside your browser, so your file is never sent to a server and never leaves your device.
Which files can I use?
You can add one PDF file at a time.
