How Do You View a PDF Online?
You view a PDF online by opening it in QuickCatPDF's PDF Viewer: click Open PDF or drop the file on the page, and it appears straight away, page by page. You can zoom, search, select and copy text, rotate the view, go full screen, print and download, without installing a reader and without uploading the file.
How to Read a PDF With QuickCatPDF
Reading a PDF takes four steps.
- Click Open PDF or drop your PDF on the page. Enter the password if the PDF is protected.
- Scroll through the pages, or type a page number in the page box.
- Zoom with + and −, or use Fit width and Fit page; use Search to find words.
- Use Print or Download if you need a copy, or Full screen for reading.
Why Use QuickCatPDF's Free PDF Viewer?
QuickCatPDF's viewer is private by design: the PDF is opened by your browser on your own device and never sent anywhere. That makes it a safe way to read bank statements, medical letters or contracts on a shared or work computer, and once the page has loaded it also works offline.
It's quick on long documents, because pages are drawn as you scroll. Text is selectable, so you can copy a paragraph or an account number, and search shows how many matches there are and jumps between them. In our test, a search for "lazy dog" found all 360 matches in a 12-page document.
The viewer is for reading. It doesn't add comments, fill in forms or sign documents in this version.
What Can You Do in the Viewer?
The viewer covers the everyday reading jobs.
| You want to | Use |
|---|---|
| Read on a phone | Fit width (default) and scroll |
| Find a word or number | Search, then the arrows or Enter to move between matches |
| Copy text | Select it with the mouse or finger and copy |
| Read a sideways page | Rotate |
| Read without distractions | Full screen |
| Keep or print a copy | Download or Print |
Keyboard shortcuts work too: Ctrl+F jumps to search, and + and − zoom. To turn pages into images, use PDF to Image; to publish a PDF as a web page, use PDF Live Page.
