Frequently asked questions
How do I sign a PDF for free without an account?
Choose your PDF, draw your signature with a mouse or finger (or type it, or upload a photo of it), press Add to page, drag it into place and press Download signed PDF.
Is this a legally valid e-signature?
This adds an image of your signature (an "electronic signature"), which is accepted for many everyday documents such as forms, rental agreements and declarations. Some documents, such as certain government filings in India, require a digital signature certificate (DSC) or Aadhaar eSign instead. Check what the recipient accepts.
Can I use a photo of my signature?
Yes. Choose Upload and pick a photo of your signature on white paper. The paper is made transparent automatically.
Is my signature stored anywhere?
No. Your signature and the PDF stay in your browser and are not saved or uploaded. Closing the tab erases them.
Can I add the date or my name too?
Yes. Use Add date or Add text to place today's date, your name, initials or place on any page.
