How to Use Google Chrome as Your Default PDF Reader on Windows

Chrome includes a built-in PDF viewer that opens files quickly, supports full-text search, and handles most common PDF tasks without any additional software. If you’re already using Chrome as your browser, setting it as your default PDF viewer means one less application to maintain.

This guide covers what Chrome’s PDF viewer can and can’t do, and walks through how to change your default PDF app on both Windows 10 and Windows 11.

What Chrome’s PDF Viewer Can Do

Chrome uses the PDFium rendering engine, the same engine used by Android and other Chromium-based browsers, to display PDF files. Out of the box, it supports:

• Full-text search (Ctrl+F) across the entire document
• Page thumbnail navigation in a collapsible sidebar
• Zoom controls and fit-to-page options
• Basic fillable forms (AcroForm standard)
• Printing, including Save as PDF via the print dialog
• Rotate pages and two-page spread view
• Download the original file from the toolbar

For most everyday tasks, such as reading reports, reviewing invoices, filling out forms, and printing documents, this covers everything you need.

What Chrome’s PDF Viewer Can’t Do

Chrome is a PDF reader, not a PDF editor. It doesn’t support:

• Highlighting, annotations, or sticky notes
• Digital signatures or certificate-based signing
• Merging, splitting, or rearranging pages
• OCR on scanned documents
• PDF/A or PDF/X archival formats
• LiveCycle Designer forms (an Adobe-specific format, uncommon but still in use)

If your work involves any of these, you’ll still want a dedicated PDF application. Chrome can still be your default for quick reading, with a separate app available when you need it.

How to Set Chrome as Your Default PDF Viewer

There are three ways to do this on Windows. The right-click method is the quickest.

Method 1: Right-Click a PDF File

1. Right-click any PDF file in File Explorer.
2. Select Open with > Choose another app.
3. Select Google Chrome from the list.
4. If Chrome isn’t listed, click More apps, then Look for another app on this PC. Navigate to: C:\Program Files\Google\Chrome\Application\chrome.exe
5. Check Always use this app to open .pdf files, then click OK.

Method 2: Windows Settings (Windows 11)

1. Open Settings with Windows + I.
2. Go to Apps > Default apps.
3. Search for Google Chrome and click it.
4. Find .pdf in the list of file types and click the current default next to it.
5. Select Google Chrome and confirm.

Method 3: Windows Settings (Windows 10)

1. Open Settings with Windows + I.
2. Go to Apps > Default apps.
3. Scroll down and click Choose default apps by file type.
4. Find .pdf in the list and click the app shown next to it.
5. Select Google Chrome from the dropdown.

If Chrome Doesn’t Appear in the List

This usually happens when Chrome is installed in a non-standard location, or the Open With dialog isn’t showing all available applications. To fix it:

• In the Open With dialog, click More apps (Windows 11) or Look for another app on this PC (Windows 10), then browse manually to chrome.exe. The default path is C:\Program Files\Google\Chrome\Application\chrome.exe. On some systems it may be under C:\Program Files (x86)\ instead.
• If Microsoft Edge keeps resetting as the default after a Windows update, repeat the steps above. Windows 11 22H2 and later are better about respecting user-set defaults, but this can still happen after major updates.
• Alternatively, right-click the PDF, select Properties, and use the Change… button next to ‘Opens with’ at the top of the General tab.

Adjusting Chrome’s PDF Behavior

You can control whether Chrome opens PDFs directly in the browser or automatically downloads them to disk:

1. Open Chrome and go to the three-dot menu > Settings.
2. Go to Privacy and security > Site settings.
3. Scroll down to Additional content settings > PDF documents.
4. Toggle between Open PDFs in Chrome and Download PDFs.

The Download PDFs option is useful if you prefer to save files before reading them, or if you frequently open PDFs in a separate editor afterward.

Extending Chrome’s PDF Features With Extensions

If you need annotation or signing tools but don’t want to install a full desktop app, several free Chrome extensions fill the gap:

• Adobe Acrobat (Chrome Extension) — adds highlighting, fill & sign, and PDF-to-Word conversion directly in the browser.
• Kami — annotation and collaboration tools, well-suited for document review workflows.
• Xodo — a capable PDF viewer and annotator with form-filling support.
• AskYourPDF — uses AI to let you search and ask questions about the contents of a document.

Summary

Chrome’s PDF viewer is a practical default for most users. It opens files fast, handles everyday reading and form-filling without issue, and doesn’t require a separate installation. The main limitation is that it doesn’t support editing or annotation — for those tasks, you’ll still need a dedicated app.

Setting Chrome as your default takes about a minute using any of the methods above. If you later decide you prefer a different app, the same steps apply — just select a different default.
