Chromebooks cannot install traditional desktop PDF apps, but signing PDFs in Chrome is just as easy. Here is how to sign a PDF on a Chromebook for free — directly in the browser, with a drawn or typed signature.
On your Chromebook, open Chrome and go to pdfeditor.onl/sign-pdf. No Linux or Android app is needed — the signing tool runs entirely in Chrome.
Click the upload area and select the PDF from your Chromebook's Files app — either local storage or Google Drive. Both are accessible from the Chrome file picker.
Tip: If the PDF is shared in Google Drive, download it first to the Chromebook Files app, then upload it to the sign tool for local processing.
Use the touchpad or an external mouse to draw your signature in the signature pad. Chromebook trackpads support click-and-drag drawing. If you have a touchscreen Chromebook, sign with your finger directly.
Drag the signature overlay to the correct position on the document page. Use the size handles to scale it to fit the signature line.
Click Download PDF. Chrome saves the signed file to your Downloads folder. Upload it back to Google Drive if needed — or email it directly from Chrome.
Yes. Touch input in the browser signature pad works on touchscreen Chromebooks, giving you a natural finger signature.
After loading the tool once while online, Chrome caches the assets. You can use the sign tool offline for locally stored PDFs if the browser cache is intact.
