How to add a signature to a PDF in Chrome
Updated 23 September 2026
Chrome opens PDFs, so it's natural to expect it to sign them. It can't really: the built-in viewer can fill in some form fields and, depending on your version, draw on the page, but there's no proper signature tool. Here's how to sign a PDF in Chrome anyway, for free.
What Chrome's PDF viewer can and can't do
- It can fill in PDF forms that were made fillable, and save a copy.
- Recent versions can draw and highlight on the page, depending on your device.
- It can't save a signature to reuse, place a typed signature, or add text anywhere on the page.
Sign a PDF in Chrome with SignFree
SignFree runs inside Chrome and does the signing on your computer, so the file isn't uploaded.
- 1Open signfree.org in Chrome.
- 2Drag your PDF onto "Sign it yourself", or click Choose a PDF.
- 3Click Signature, then draw or type it. Tick "Remember on this device" to reuse it.
- 4Click where the signature goes and resize it to fit the line.
- 5Add text, dates or checkmarks anywhere on the page.
- 6Click Download PDF.
Why not a Chrome extension?
PDF signing extensions often need permission to read every website you visit, and many are trials in disguise. A website needs no permissions and no install, so there's nothing to remove afterwards.
Collect other signatures from Chrome
Choose "Send it for signing" to email the PDF to other people for signature. They sign from the link in any browser, and everyone gets the signed PDF with a signature certificate.
