What is a DJVU file?
The .DJVU file extension primarily represents a DjVu Image. This is a compressed document image format originally created by AT&T Labs. People use it to store scanned documents, digital books, and high-resolution images. The format separates text and background layers to keep file sizes small.
Sometimes, the .DJVU extension appears on files encrypted by the STOP DJVU Ransomware. If a standard file like a photo or document suddenly gains this extension and becomes unreadable, malware likely changed it.
How to open DJVU files?
To read a standard .DJVU document on your computer, you need specific software. Windows users often install WinDjView or a multi-format document reader like Sumatra PDF. Linux and macOS users often rely on DjVuLibre and its command-line tools.
Best practices and troubleshooting
Because a .DJVU file has multiple possible meanings, viewer.online/djvu analyzes .DJVU files to identify their exact format and creator software. It shows which programs can open the file, and usually previews it. If your file is a valid document, we recommend file conversion to a more standard target format like .PDF on convert.guru.
Summary
viewer.online/djvu directly opens and previews .DJVU files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
