How to sign a PDF on a Chromebook
Chromebooks are built around the browser, which makes them a perfect match for an in-browser signer: open the page, load your PDF, sign with the touchscreen, touchpad, or a stylus, and download. No Android app needed, no account, and the file is never uploaded to a server.

Sign a PDF on your Chromebook in four steps
- 1
Open the free signer in Chrome
Click Choose file and pick your PDF from the Files app, or drag it onto the page. Documents in the Downloads folder load instantly and stay on the device.
- 2
Create your signature
On a touchscreen Chromebook, draw with your finger or a USI stylus for the most natural line; otherwise use the touchpad, type your name in a handwriting style, or photograph your signature with the camera.
- 3
Place and adjust
Drag the signature into place and resize it. Add initials or dates on other pages the same way.
- 4
Download the signed PDF
The flattened PDF saves to Downloads. Attach it from the Files app to Gmail or upload it wherever it needs to go.
Chromebook specifics worth knowing
Keep it in Downloads to keep it local
ChromeOS blurs local and Drive storage. A file in Downloads stays on the device; a file in a synced Drive folder is already in the cloud before you sign it. For confidential documents, work from Downloads, the signer itself never uploads anything either way.
No Android app required
Many PDF apps on Chromebooks are Android apps running in a compatibility layer, with the same install-and-account friction as on a phone. The signer is a plain web page, ChromeOS's native habitat, and needs none of that.
School and managed devices
On managed Chromebooks where the Play Store is disabled, a web page is often the only signing option available at all, and this one works even in a guest session.
Frequently asked questions
- Does this work on a school or managed Chromebook?
- Usually yes: it's an ordinary website, so it works wherever the web isn't blocked, including devices with the Play Store disabled, and in guest sessions. Nothing installs, so there's nothing for device policies to forbid.
- Is my document uploaded when I sign on a Chromebook?
- No. The signing happens in the browser tab on the device. Note the one ChromeOS subtlety: files stored in a synced Google Drive folder are already in the cloud, keep sensitive PDFs in Downloads to keep the whole flow local.
- Can I use a stylus?
- Yes, on touchscreen Chromebooks, USI styluses and fingers both work in the drawing pad, and a stylus gives the smoothest signature. Non-touch models can draw with the touchpad or use the typed and photo options.
