How to open .UVG files on iOS
To open .UVG files on iOS, in the Files app, tap the .UVG file; if Quick Look can’t preview it, share it to the app that created it (if available) or transfer it to a desktop to open/convert.
Step-by-step instructions
- In the Files app, tap the .UVG file; if Quick Look can’t preview it, share it to the app that created it (if available) or transfer it to a desktop to open/convert.
Common issues
No app can open the .UVG file
Many mainstream image viewers do not support DECE Graphic directly, even if the OS recognizes the extension as an image type.
- Ask the sender which application generated the file and open it with that application.
- Export or re-save from the source application to a common format like PNG or JPEG.
File opens but looks corrupted or blank
The file may be incomplete (partial download/transfer) or not actually a DECE Graphic image despite the .uvg extension.
- Re-download or re-transfer the file (prefer a direct copy rather than forwarding through apps that might alter files).
- Confirm with the sender that the file is meant to be a .UVG (DECE Graphic) and not a different file mistakenly renamed.
Linux shows a MIME type but still won’t preview
MIME association (e.g., via shared-mime-info) identifies file type categories, but previewers still need a decoder/codec to render the image.
- Try a different viewer/editor application installed on your system (some apps handle more niche formats than others).
- If none work, open the file on the system where it was created and export to PNG/JPEG.
Security note
.UVG files are treated as images (image/vnd.dece.graphic), so they typically don’t contain scripts/macros, but malformed image files can still exploit bugs in image decoders—avoid opening unexpected .UVG files in obscure or untrusted viewers.
