Device & OS
not provided
Scenario
Attempting to fill out forms and apply a digital signature to a PDF document opened within a web browser.
Observed behavior
The Fill & Sign tool is completely missing in modern browser PDF viewers like Chrome and Edge, whereas it was previously available via add-ons in older browsers like Internet Explorer.
Before you start

Ensure you have a dedicated desktop PDF reading application installed on your computer, as built-in browser viewers are primarily designed for reading rather than editing.

Solution 1Recommended

Download the PDF and Open in a Dedicated Desktop App

Bypass the limited built-in browser viewers by downloading the document to your local drive and opening it in a full-featured desktop PDF application.

Google Chrome and Microsoft Edge use their own lightweight, built-in PDF viewers. These native viewers are designed for quick reading and basic printing to improve browser security and speed. Because of this, they do not include advanced editing tools like the Fill & Sign feature found in dedicated Adobe or WPS PDF applications.

1
Save the PDF locally

While viewing the PDF in Google Chrome or Microsoft Edge, click the 'Download' or 'Save' icon located in the top-right corner of the viewer toolbar to save the file to your computer.

2
Open with a dedicated PDF app

Navigate to the folder where you saved the downloaded file. Right-click the document, select 'Open with', and choose a full-featured PDF reader like WPS Office or Adobe Acrobat.

3
Access Fill & Sign tools

Once the document is open in your desktop application, navigate to the 'Tools' or 'Edit' tab and select the 'Fill & Sign' option to type into forms and apply your signature.

Frequently Asked Questions

Why do Chrome and Edge use their own PDF viewers instead of Adobe Reader?

Modern web browsers use built-in PDF viewers to improve security and performance. This prevents vulnerable third-party plugins from compromising your system, but it also means advanced tools like Fill & Sign are excluded from the browser environment.

Can I force Chrome to use Adobe Acrobat for viewing PDFs?

You cannot run the old desktop add-on inside modern Chrome, but you can install the official Adobe Acrobat extension for Chrome from the web store to access more features, or set your browser to automatically download PDFs instead of opening them.

Is there a way to sign a PDF online without downloading it?

Yes, you can use cloud-based PDF editing tools like WPS PDF Online or Adobe Acrobat Web. By uploading your document to these online services, you can access full Fill & Sign capabilities directly from your browser.
