Google Drive PDF Viewer: How to Use It and 5 Best Alternatives

Google Drive PDF Viewer is a built-in file-preview tool that lets you open and read PDFs stored in Drive without installing a separate app. It works well for quick viewing and sharing files with a teammate or client. For deeper reading, OCR, advanced annotations, PDF editing, and page management, you will need to step outside Drive and into a dedicated PDF tool such as UPDF.

What Is Google Drive PDF Viewer?

Google Drive PDF Viewer is part of Drive's built-in file-preview system that lets you view and open PDF files. It is not a standalone desktop PDF editor. Double-click any PDF in your Drive, and it opens either in the overlay preview or a new browser tab.

The PDF Viewer in Google Drive gives you access to basic features, including page navigation, zoom, printing, downloading, and sharing links.

The "Open with" menu lets you hand the file off to any compatible app connected to your account, so you are not locked into Drive's own interface. Eligible Workspace and Gemini plan users also see AI summary cards when they open a PDF, plus the option to ask Gemini questions about the document's content. To learn more, read Google's official documentation about using Gemini with PDFs in Drive.

Note: Google Drive PDF Viewer is a different tool from Chrome's own built-in PDF viewer, which opens local files and downloaded PDFs outside of Drive.

How to View a PDF in Google Drive

Open a PDF in Google Drive on the Web

1. Sign in to Google Drive in your browser.
2. Upload the PDF or locate it in an existing folder.
3. Double-click the file to open it.
4. Depending on your settings, it loads in the overlay preview or a new tab.
5. Use the sidebar and toolbar to navigate, zoom, print, or download.

The overlay preview also shows a Share button and a three-dot menu with options like "Open with," rename, and move to folder. So, most everyday file management happens right there without leaving the preview.

Open a PDF in the Google Drive Mobile App

Google Drive's Android and iOS apps have a similar starting approach. Tap the file in the Drive app, and it opens in preview mode. After that, the two platforms diverge a bit.

On Android, tapping the pencil icon in the bottom corner brings up a small annotation toolbar with a pen, highlighter, and eraser, all with adjustable brush size and color, plus undo and redo. iOS doesn't offer that markup toolbar inside the Drive app. However, both apps now also support using Gemini to ask document-related questions.

Tip: If you expect to read a PDF without a network connection, mark it available offline ahead of time from the file's three-dot menu, since Drive won't fetch new content once you lose your connection.

What Can and Can't Google Drive PDF Viewer Do?

PDF Viewer in Google Drive is usually sufficient when users only need to open or share a PDF. When the job involves a more focused reading environment, heavier annotation, editing text/image, or page organization, downloading the PDF and opening it in UPDF fills the gap without disrupting the rest of your Drive workflow.

UPDF lets you read PDFs with a more enhanced experience, including AI-powered smart reading, light/dark modes, multiple viewing modes, changeable backgrounds, text-to-speech, and more.

You also get a full PDF annotation toolkit to highlight, comment, add stamps/sticky notes, and more.

Above all, you get an advanced PDF editor at your side that can edit text/images, organize pages, perform OCR, password-protect, and more.

Download UPDF and read and handle PDFs with the tool that knows what a PDF actually needs.

How to Edit a Scanned PDF from Google Drive

Option 1: Open the Scanned PDF with Google Docs

1. Right-click the scanned PDF in Google Drive.
2. Choose Open with and tap Google Docs.

Docs runs its own text recognition and drops the extracted content into a new and editable document.

Limitation:

1. This method is useful when you need to extract and rewrite text.
2. It converts the content into a Google document rather than editing the original PDF.
3. It won't preserve the original PDF. Fonts, columns, tables, images, spacing, and page breaks may look different from the original.

Option 2: OCR and Edit the Scanned PDF with UPDF

When you want to stay in the PDF format, download the scanned PDF from Drive and open it in UPDF. UPDF has a built-in OCR PDF feature that makes the text searchable, selectable, and editable while preserving most of the PDF's layout and font. So, run OCR in UPDF by clicking Tools > OCR.

After you have completed OCR, you can use UPDF to further edit the scanned PDF. You can add/delete/replace text and images. You can also reorganize pages as needed. Once every edit is made, save the updated version and upload it back to Google Drive.

This workflow is more suitable when users want to:

1. Process scanned contracts, research papers, textbooks, receipts, or forms.
2. Edit the recognized content without rebuilding the entire document in Google Docs.
3. Reduce unnecessary reformatting.

So, download UPDF for free, perform OCR, and edit your scanned PDF in one tool.

5 Best Google Drive PDF Viewer Alternatives

1. UPDF — Best for OCR, Deep Reading, and PDF Editing

UPDF is a feature-packed PDF editor. It offers dedicated reading modes, full-text search, bookmarks, highlights, and notes, which enhance the ordinary reading experience you get in the Google Drive PDF Reader.

Being a PDF editor, UPDF supports editing PDF text and images (add, delete, replace) without impacting the existing layout and fonts. You also get a powerful OCR scanner to handle scanned files and a complete page organization section to add, rearrange, replace, delete, split, or extract pages.

UPDF features make it suitable for long reports, research papers, textbooks, and scanned documents. However, there is no direct Google Drive plug-in. You must first download the PDF or access a locally synced copy through Google Drive for desktop, then work on it in UPDF. After you have made your edits, upload the finished file back to Drive.

In his hands-on review of Adobe Acrobat alternatives, author Nicholas C. Rossis highlights UPDF's fast performance, intuitive interface, editing and annotation tools, and page-management features. He said he chose the discounted lifetime license for UPDF over Acrobat's steeper annual cost.

So, download the PDF from Google Drive and open it in UPDF whenever you need more than basic viewing.

2. Adobe Acrobat — Best for Professional PDF Workflows

Acrobat remains the industry standard for advanced editing, forms, digital signatures, and Adobe's broader document ecosystem. The free Reader covers viewing and light markup, but text editing, form creation, and OCR sit behind an expensive paid Acrobat Pro subscription. Google Drive access and integration depend on which Adobe product and subscription you are using.

3. Kami — Best for Teachers and Students

Kami is your Google Drive PDF Viewer alternative if you are involved in the academic ecosystem. It offers native Google Classroom and Drive integration, so assignments open, get marked up, and sync back without any extra exporting or file juggling.

Teachers can highlight/comment and leave audio or video feedback on a student's PDF. Similarly, students can respond with text, drawings, or voice notes of their own. So, it's a strong fit for classroom use rather than general business PDF work.

4. Drawboard PDF — Best for Stylus Annotation

Drawboard focuses on handwriting, freehand drawing, and pressure-sensitive pen input. It is a natural choice for tablet and Surface users who prefer writing over typing. Installing the Drawboard PDF Google Workspace app lets you open a Drive file directly and sync changes back automatically.

5. Lumin PDF — Best for Browser-Based Access

Lumin is a browser-based tool that lets you open Google Drive files directly in its editor after you have connected the Lumin app to Google Drive.

Lumin opens Drive files directly in its browser-based editor, so there's no separate download-and-upload step. The free plan covers basic editing, signatures, and annotation on a limited number of documents each month. Paid tiers add unlimited collaboration and deeper text editing. It is a suitable Google Drive PDF Reader if you need to edit, sign, or annotate a PDF without leaving your browser or juggling a separate download.

Conclusion

Google Drive PDF Viewer handles quick PDF viewing, sharing, and storage well, and Google Docs is a fast way to extract text from a scanned file when matching the original formatting doesn't matter.
