Frequently asked questions
Is this a legally binding digital signature?
It places an image of your signature on the page, like signing on paper. It is not a certificate-based digital signature. Check what your recipient requires.
Can I sign more than one page?
Yes. Choose “All pages” if every page needs your signature.
Is Sign PDF really free?
Yes. There is no signup, no watermark and no paid plan. The site is supported by ads.
Is my data sent to a server?
No. Your file is processed by code running in your browser. The page only downloads the open-source libraries it needs (for OCR, also the language data), never your file.
