Sign PDFs on Chromebook

Chromebooks are designed around the web browser, which makes SigPDF a natural fit. Unlike Windows or Mac computers, ChromeOS does not come with desktop PDF editing software. While you can install Android apps from the Play Store, they often feel clunky on a Chromebook and consume valuable storage space. SigPDF runs entirely in the Chrome browser, which is already the core of your Chromebook experience. There is nothing to install, no extension to add, and no account to create. Simply navigate to SigPDF, upload your PDF, and sign it.

Chromebook users face a unique challenge when it comes to document signing. Traditional desktop software like Adobe Acrobat does not run on ChromeOS, and Google's built-in PDF viewer only lets you view and annotate documents — not add proper signatures. SigPDF provides a full desktop-class signing experience in the browser, with a spacious PDF viewer, intuitive signature tools, and the ability to add text fields, dates, initials, and images alongside your signature.

For students and educators who rely on Chromebooks in schools and universities, SigPDF is particularly useful. Permission slips, enrollment forms, academic agreements, and other documents that require signatures can be handled quickly without IT needing to install any software. Because SigPDF processes documents entirely in the browser, it works within the security and management policies that school administrators enforce on managed Chromebooks.

SigPDF supports Chromebooks with touchscreens and styluses, so if you have a convertible Chromebook (like the Lenovo Duet, ASUS Chromebook Flip, or HP Chromebook x360), you can draw your signature directly on the screen. For Chromebooks without touchscreens, you can draw using the trackpad or mouse, type your name and choose a handwriting font, or upload an image of your signature.
