PDF viewer

render in-browser with pdf.js

Drop one or more PDFs and read them. Use the page arrows to navigate; if you've dropped multiple files, switch between them with the file picker.

When to use this tool

A bare-minimum PDF reader for the browser when you don't want to download a file or open another app. Useful for quick previews before deciding what to do — confirm a file is what you expected before sending it to merge / split / watermark, or read a sample without cluttering the Downloads folder.

Step by step

1. Drop one or more PDFs into the drop zone.
2. If you dropped one, page 1 renders immediately.
3. If multiple, pick which file to view from the dropdown in the viewer bar.
4. Use ← / → to navigate pages.
5. Click "Clear" to drop the loaded files and start fresh.

Common use cases

• Confirm before processing. Drop a file in here to make sure it's the right document before sending it to a destructive tool.
• Quick read. Skim a PDF without saving it to disk.
• Visual diff against the inspector. Open the same file here and in Metadata inspector in two tabs to read while seeing the metadata.
• Mobile-friendly read. A simple viewer that works on phones, where opening PDFs in some browsers is awkward.

What this viewer doesn't do

• Search inside text (yet)
• Show outline / bookmarks
• Zoom by pinching (uses fit-to-width by default)
• Print directly (use your browser's print dialog after rendering, or download first)
• Render encrypted PDFs that require a password (those don't open in pure-browser pdf.js)
