Sign Any PDF You Find Online, Directly From Your Browser
Most browsers open PDFs by default, so that's often where a contract lands first. The NomaSign extension for Chrome and Edge adds a 'Sign with NomaSign' button to it. One click adds the PDF to your account, ready for signature fields and sending.
Free to install · NomaSign account required · No credit card for trial
Sign PDFs Wherever You Find Them
An email attachment, a link on a client's website, a file in Google Drive: if your browser is your PDF viewer, that's where the document already is. The extension simply makes that the starting point. Click 'Sign with NomaSign', the PDF goes into your NomaSign account, and you carry on with signature fields and sending as usual. It's the quicker route for anyone who lives in their browser.
Install from your browser's store
Click the Chrome or Edge button above. You'll be taken to the official store listing. Click 'Add to Chrome' or 'Get' on Edge.
Pin the extension to your toolbar
Click the Extensions (puzzle) icon in your browser toolbar, find NomaSign, and click the pin icon so it's always visible.
Open any PDF and click Sign
Open a PDF on a website, in Google Drive or OneDrive, or straight from your computer. The extension spots it and shows a 'Sign with NomaSign' button.
Everything You Need to Sign PDFs in the Browser
Automatic PDF Detection
The extension watches for PDF files as you browse. When it finds one, a 'Sign with NomaSign' button shows up. You don't have to do anything.
One-Click Signing Workflow
One click adds the PDF to your NomaSign account. From there you add your signers, place the signature fields and send it off, the same way you would in the web app.
Works With Local Files
Enable file URL access in one step and sign PDFs opened directly from your hard drive, desktop, or shared network drives.
Works with Google Drive & Microsoft 365
Open a PDF from Google Drive or OneDrive and add it to NomaSign from there. Once everyone has signed, the completed copy is saved back to your own cloud storage.
Full Audit Trail
Signatures collected through the extension carry the same evidence as the web app: timestamps, IP addresses and device information.
No App Needed for Signers
Signers get a secure email link and sign in whatever browser they use. There's no account to create and nothing to install.

Browser Extension FAQ
What does the NomaSign browser extension do?
