Frequently Asked Questions
How do I sign a PDF online?
Upload your PDF, create your signature by drawing it, typing your name or uploading an image, then click the page where it belongs. Adjust its position and size, click Sign PDF and download the signed file.
Is my PDF uploaded when I sign it?
No. NeatPDF signs your PDF in your browser. The file and your signature are never sent to a server, and your signature is forgotten when you leave the page.
What kind of signature does this create?
A simple electronic signature: an image of your signature, drawn onto the page. It is not a certificate-based digital signature, and the file carries no audit trail of who signed it or when. Many everyday documents only need a signature like this, but check what the person or organisation asking for it accepts.
Can I sign a PDF on my phone?
Yes. Draw your signature with your finger, or type your name. The tool works in Chrome, Safari, Firefox and Edge on iPhone, Android, tablets and desktops.
Can I put my signature on more than one page?
Yes. Move to any page, click where the signature belongs, and repeat on as many pages as you need. The same signature is used each time.
Can other people move or remove my signature?
Your signature is drawn into the page content rather than added as a movable annotation, so it shows the same in every PDF viewer and can't be dragged off the page. Like anything in a PDF, it can still be edited with PDF editing software.
What if my PDF already has a digital signature?
NeatPDF warns you. Adding your signature changes the file, so an existing certificate-based signature will show as invalid. Sign a copy, or ask whoever signed it first to sign last.
Is signing PDFs free?
Yes. You can sign up to 3 PDFs a day for free, as part of the 3 free tasks shared across every tool, with files up to 50 MB. Need more today? A day pass is paid once and covers every tool for 24 hours.
