How to open .DJV files
Use these platform-specific instructions to open .DJV files safely.
Windows
- If the file doesn’t open, install a DjVu-capable viewer (for example, Okular) and then right-click the .DJV file → Open with → choose the viewer.
- If you need to convert it, use DjVuLibre tools (for example, ddjvu) on a system where they’re available to export to a more common format.
Mac
- If you don’t already have a DjVu-capable viewer installed, you may need to open the file on a different system or use DjVuLibre tools where available.
- If you have a DjVu viewer installed, Control-click the .DJV file → Open With → select the DjVu-capable app.
Linux
- Open the file in a DjVu-capable viewer such as Okular (supported format: DjVu).
- For conversion or troubleshooting, use DjVuLibre tools like ddjvu to decode/export the file.
iOS
- If the Files app cannot preview the .DJV, transfer the file to a desktop system and open it with a DjVu-capable viewer (for example, Okular) or convert it with DjVuLibre.
Android

Security notes
- Treat DjVu (.djv/.djvu) as untrusted input when it comes from unknown sources: it relies on complex decoders, and malformed files can potentially trigger viewer/parser bugs.
- Prefer opening unknown .DJV files in well-maintained viewers and consider converting with DjVuLibre command-line tools if you need a safer, simpler output format for sharing.
- Be cautious with files that arrive with unexpected double extensions or mismatched labels (for example, something named .djv that was actually downloaded from an untrusted source); verify the source before opening.

OS-specific troubleshooting
What is a .DJV file?
.DJV is a common extension for DjVu (often also seen as .djvu), a format designed for efficient storage and display of scanned documents and page images. DjVu files are structured as chunked containers (for example, FORM:DJVU) that can combine foreground text/line art and background images. The registered Internet media type is image/vnd.djvu.
Background
DjVu is widely associated with scanned documents (such as books, papers, and archival scans) where file size matters but readability must remain high. It is often used as an alternative to PDF for scan-heavy content because it can compress complex page images efficiently.
In practice, .DJV files behave more like document pages than typical “single-photo” image formats: they may contain one page or multiple pages, and viewers often provide page navigation and zooming suitable for reading.
On the web and in systems that rely on content types, DjVu files (including .djv and .djvu) are commonly expected to be served with the MIME type image/vnd.djvu.
Common MIME types: image/vnd.djvu

Common .DJV issues
The .DJV file won’t open or shows as an unknown format
Many systems don’t include DjVu support by default, so the file won’t open until you install a DjVu-capable viewer or toolset.
- Try a DjVu-capable viewer (for example, Okular on platforms where it’s available).
- Use DjVuLibre tools (such as ddjvu) to decode/convert the file to a more widely supported format.
It opens, but pages render incorrectly or look corrupted
DjVu is a specialized, chunk-based format; a partial download or a buggy/outdated decoder can cause rendering artifacts or missing content.
- Re-download or re-copy the file to ensure it is complete (especially if it came from the web).
- Try opening the same file with an alternative DjVu decoder (for example, DjVuLibre tools like ddjvu) to confirm whether the file or the viewer is the problem.
You can’t preview .DJV on mobile
Mobile OS previewers often do not include DjVu rendering, so tapping the file may show a blank preview or an error.
- Send the file to a desktop system and open it with a DjVu-capable viewer (for example, Okular).
- If you need it on mobile, convert it on a desktop using DjVuLibre (for example, ddjvu output to a more common format) and then transfer the converted result back.
FAQ
Is .DJV the same as .DJVU?
Yes in common usage: .djv is a common extension for DjVu files (often also saved as .djvu). Both are typically associated with the same MIME type: image/vnd.djvu.
What MIME type should a .DJV file use?
image/vnd.djvu (as listed in the IANA media types registry and DjVu plug-in documentation).
Can I convert a .DJV by renaming it to .PDF or .JPG?
No. Renaming only changes the filename extension; it does not convert the content. Use a DjVu decoder/converter such as DjVuLibre (for example, ddjvu) to export to another format.
What are .DJV files typically used for?
They are commonly used for scanned documents and page images where efficient compression and readability are important (for example, book scans and archives).
