PDFelement - Powerful and Simple PDF Editor
Need more than browser-based PDF viewing? Edit, convert, OCR, annotate, and manage PDFs with PDFelement.
Google Chrome already includes a built-in PDF viewer, so you can open and read many PDF files directly in the browser without installing extra software. However, a PDF reader extension can still be useful when you need additional features such as advanced viewing controls, annotations, PDF editing tools, or the ability to send a PDF directly to a desktop reader.
PDF remains one of the most widely used formats for documents because it preserves fonts, layouts, images, and other elements across devices. A PDF reader Chrome extension can add extra functionality to Chrome's native PDF handling and make it easier to read, mark up, manage, or open PDFs in another application.
There are many PDF reader Chrome extensions available, but their features and use cases vary. Below, we compare five options that are still available in 2026, including extensions for browser-based PDF viewing, opening files in external readers, and more advanced PDF workflows.
What Is a PDF Reader Extension? Check Its Main Benefits
A PDF reader plug-in or extension adds extra PDF functionality to your web browser. Chrome can already open PDFs with its built-in viewer, but an extension can provide a different viewing interface, additional annotation tools, or a workflow for opening PDF files in a separate desktop application.
Depending on the extension, you may be able to search documents, zoom and navigate pages, highlight content, draw on PDFs, add text, fill forms, or hand files off to an external PDF reader. The exact features vary from one extension to another.
Here are some of the main reasons users install a PDF reader extension for Chrome:
- A PDF reader for Chromebook or Chrome can add viewing or annotation features beyond the browser's default PDF experience.
- Some extensions let you open local or remote PDF files directly in a customized browser viewer.
- Certain extensions can send a PDF link to an external application such as Adobe Acrobat Reader or another desktop PDF viewer.
- Extensions based on PDF.js can provide additional themes, navigation controls, drawing tools, or page-management functions.
- Many basic PDF reader extensions are free, although advanced PDF editing or conversion features may require a paid service.
If Chrome's built-in PDF viewer already covers your needs, you may not need an extension at all. A dedicated extension makes more sense when you want a specific reading interface, additional PDF tools, or integration with a desktop PDF application.
Top 5 PDF Reader Chrome Extensions in 2026
The following PDF reader Chrome extensions cover different use cases, from replacing Chrome's default viewer to opening PDF links in external desktop software. Ratings and user counts below are Chrome Web Store snapshots from September 2026 and may change over time.
1. PDF Viewer (PDF.js)
PDF Viewer is the official Chrome extension of the PDF.js project. It uses Mozilla's open-source PDF.js technology to display PDF files directly in the browser and can replace Chrome's default PDF viewer.
This extension is particularly useful for users who prefer the PDF.js viewing experience. It supports online PDFs as well as local PDF files when file access is enabled in Chrome's extension settings. Unlike a full PDF editor, its primary purpose is standards-based PDF rendering and reading.

- Users: 1,000,000+
- Best for: Replacing Chrome's default PDF viewer with a PDF.js-based viewer
What to Know: PDF Viewer focuses on displaying PDFs rather than providing a complete PDF editing suite. Local-file access must be enabled separately if you want the extension to open PDFs stored on your computer.

2. Open in PDF Viewer
Open in PDF Viewer is a lightweight Chrome extension designed for a different purpose: instead of replacing Chrome's built-in viewer, it sends a PDF link to a PDF application installed on your computer.
After setup, you can right-click a PDF link and choose to open it with your configured desktop PDF viewer. The extension first downloads the file and then launches the selected application. It requires a native-client component to connect Chrome with software installed on Windows, macOS, or Linux.
- Rating: 3.2/5
- Ratings: 136
- Users: 100,000+
- Best for: Opening browser PDF links in a preferred desktop PDF viewer
What to Know: This is not a standalone PDF reader. You need a compatible PDF viewer installed on your computer and must configure the native connection before the extension can launch PDFs externally.

3. Open in PDF Reader
Open in PDF Reader is another extension for users who prefer to read PDFs in a desktop application rather than inside Chrome. Despite its name, the extension itself is mainly a bridge between PDF links in the browser and an external PDF reader.
After installation and configuration, you can right-click a PDF link and select the option to open it in your preferred viewer. The file is downloaded to the default downloads directory and then opened using the configured desktop reader, such as Adobe Acrobat Reader or another compatible PDF application.
- Rating: 3.5/5
- Ratings: 50+
- Users: 90,000+
- Best for: Sending PDF links from Chrome to an external desktop reader
What to Know: A native client is required because browser extensions cannot normally execute desktop applications directly. This makes setup more involved than using Chrome's built-in viewer or a browser-based PDF extension.

4. PDF Reader and Editor
Previously listed simply as PDF Reader, this extension is now available as PDF Reader and Editor. It is based on Mozilla's PDF.js library and can be used as an alternative to Chrome's default PDF viewer for both local and remote PDF files.
Its current feature set goes beyond basic reading. In addition to page navigation and multiple viewing themes, the extension supports adding text and images, drawing on PDFs, cropping document areas, extracting selected pages, and displaying PDF signatures.
- Rating: 4.5/5
- Ratings: 100+
- Users: 70,000+
- Best for: Users who want a customizable PDF.js reader with lightweight editing tools
What to Know: You need to enable local-file access in Chrome if you want the extension to work with PDFs stored on your device. Its editing features are useful for light browser-based changes but are not a replacement for a full desktop PDF editor.

5. Adobe Acrobat: PDF Edit, Convert, Sign Tools
The Adobe Acrobat Chrome extension is one of the most widely installed PDF extensions in the Chrome Web Store. It extends Chrome's PDF experience with Adobe tools for viewing, commenting, filling forms, signing documents, and accessing additional PDF functions from the browser.
For free PDF tasks, the extension supports viewing, downloading, printing, adding comments, sticky notes, text, highlights, and filling and signing forms. Adobe also offers premium tools for PDF conversion, creation, merging, page organization, compression, and password protection.
The extension can work with local PDFs as well as documents opened from the web. Users who already work in the Adobe Acrobat ecosystem may find the integration particularly convenient, while people who only need basic PDF viewing may find Chrome's built-in viewer sufficient.
- Rating: 4.4/5
- Ratings: 63K+
- Users: 330,000,000+
- Best for: PDF viewing, comments, forms, signatures, and access to additional Acrobat tools
What to Know: Many common viewing and annotation features are available without a paid Acrobat plan, while more advanced PDF conversion, organization, compression, and editing functions may require Adobe's premium services.

All-in-One PDF Editor for PDF Tasks Offline
Wondershare PDFelement - PDF Editor Wondershare PDFelement Wondershare PDFelement is a desktop PDF editor designed for users who need more than the viewing and lightweight annotation features provided by a PDF reader Chrome extension. It lets you edit PDF text and images, convert files, run OCR on scanned documents, annotate pages, fill forms, sign PDFs, organize pages, compress files, and protect sensitive documents.
G2 Rating: 4.5/5 |
100% Secure
For basic reading, Chrome's built-in PDF viewer or one of the extensions above may already be enough. PDFelement is better suited to workflows where you need to make changes to the actual PDF rather than simply open it in a browser.
For example, long reports, contracts, scanned files, and other document-heavy PDFs may require tools beyond browser viewing. PDFelement supports full-text editing, PDF conversion, OCR, annotations, forms, signatures, page management, and other desktop document tasks.
G2 Rating: 4.5/5 |100% Secure
When reviewing a long PDF, you can highlight important text, add comments, and mark key pages so that important information is easier to find when you return to the document. Highlights and annotations can also be changed or removed later when they are no longer needed.
For scanned or image-based PDFs, OCR can recognize text so that document content becomes searchable and editable. This is particularly useful when browser-based PDF viewing alone cannot work with text embedded in scanned pages.
PDFelement also supports common document-management tasks such as splitting and combining PDFs, reorganizing pages, converting files between formats, compressing large PDFs, applying password protection, and processing multiple files when a desktop workflow is more practical.
The key distinction is that PDFelement is positioned here as a PDF editor, not as the discontinued PDFelement PDF Reader product. If you only need to view PDFs in Chrome, use the browser's built-in viewer or one of the PDF reader extensions above.

Final Verdict
If you mainly open PDFs while browsing, Chrome's built-in viewer may already be enough. A PDF reader extension is most useful when you want a different viewing interface, extra annotation features, or a quick way to send PDFs to another reader. For full PDF editing, OCR, conversion, page management, and other advanced document tasks, use a dedicated PDF editor instead of relying on a browser extension.
