DownloadAbout Sign PDF
Sign PDF adds your signature to any document. Draw it with a mouse, finger or stylus, type your name in a handwriting style, or upload a photo of your signature (we remove the white background). Then click where it goes, resize it, and add your initials and the date.
Your document and signature stay in your browser and are never uploaded. This is a visual signature, like signing on paper; it isn’t a certificate-based digital signature.

Sign PDF: frequently asked questions
Is an online signature legally valid?
In many countries a simple electronic signature is valid for everyday agreements, but some documents need certificate-based signatures. Check what your document requires.
Is my signature saved?
No. It exists only in this tab and is gone when you close it.
Is it safe for confidential files?
Your file never leaves your device: hellpdf does this in your browser, so nothing is uploaded and there’s no file size limit beyond what your device can handle.
Is it really free?
Yes. It’s free with no sign-up, no watermark and no daily limit on the tools that run in your browser.
