How to open .UVI files on iOS
To open .UVI files on iOS, in the Files app, tap the .UVI file to try a preview; if there’s no preview/it fails, transfer the file to a desktop OS to open it with a compatible image tool.
Step-by-step instructions
- In the Files app, tap the .UVI file to try a preview; if there’s no preview/it fails, transfer the file to a desktop OS to open it with a compatible image tool.
Common issues
“Unsupported format” or the image won’t preview
Your OS may recognize .UVI as image/vnd.dece.graphic but your viewer does not include a decoder for this specific image format/variant.
- Try “Open with” and test a different image/graphics application on a desktop OS.
- If you received the file from someone, ask the sender what application/workflow produced it and whether they can export to a more widely supported image format.
File opens as a generic/binary file or the wrong app launches
The file association may be missing or incorrect even if the extension-to-MIME mapping exists in some databases or server configurations.
- Manually choose an application via “Open with” rather than double-clicking.
- On Linux, ensure your environment’s MIME database is up to date so .uvi maps to image/vnd.dece.graphic.
Web server serves the file with the wrong Content-Type
If the server does not map .uvi to image/vnd.dece.graphic, browsers and clients may mis-handle downloads or rendering.
- Configure your server to send Content-Type: image/vnd.dece.graphic for .uvi (and related extensions if needed).
- If using Apache, confirm your mime.types / mod_mime configuration includes the mapping for uvi → image/vnd.dece.graphic.

Recover a deleted or lost .UVI file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
.UVI is an image media type (image/vnd.dece.graphic), but image decoders can still have vulnerabilities; only open files from sources you trust, especially if the viewer is older.
