- Product
- Chrome and Edge Built-in PDF Viewers
- 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.
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.
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.
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.
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.
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.

Easily Fill and Sign PDFs with WPS Office
Stop struggling with limited browser PDF viewers. WPS Office provides a comprehensive PDF toolset that allows you to easily fill interactive forms, add text fields, and insert digital signatures seamlessly.
- 1. Open your document: Launch WPS Office and open your downloaded PDF file.
- 2. Navigate to Fill & Sign: Click on the 'Fill & Sign' tab located in the top navigation toolbar.
- 3. Create your signature: Select 'Add Signature' to draw, type, or upload an image of your personal signature.
- 4. Apply and save: Click anywhere on the document to insert your signature or fill out text fields, then save your finalized document.

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.
