How to open .UVG files on Android
To open .UVG files on Android, open the file from your Downloads/Files app; if it doesn’t preview, transfer it to a desktop and open it with the originating app to export to a common format.
Step-by-step instructions
- Open the file from your Downloads/Files app; if it doesn’t preview, transfer it to a desktop and open it with the originating app to export to a common format.
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.
