How to open .JPM files on Android
To open .JPM files on Android, android’s default viewers often won’t open .JPM; if it fails, move the file to a desktop JPEG 2000 tool that supports JPM and convert it to a common format.
Step-by-step instructions
- Android’s default viewers often won’t open .JPM; if it fails, move the file to a desktop JPEG 2000 tool that supports JPM and convert it to a common format.
Common issues
The file opens as “unknown format” or won’t preview
Many image viewers support common JPEG/PNG but not JPEG 2000 Part 6 (JPM), so the OS or app may not recognize the container.
- Use a JPEG 2000-capable viewer/converter that explicitly lists support for .JPM (see FileInfo’s .JPM page).
- Convert/export the JPM to a more widely supported image format for viewing in standard apps.
Opens in an app but shows blank pages or missing content
JPM is a compound document format; partial support in some tools may display only parts of the compound content or fail on multi-page/compound structures.
- Try a different JPEG 2000 tool that supports JPM/Part 6 compound documents (not just basic JP2 viewing).
- If possible, re-export/convert using the producing workflow/tool to a simpler format for compatibility.
“Corrupt file” or fails after download/transfer
Because JPM is less common, some systems mishandle transfers (e.g., truncation) or the file may actually be incomplete.
- Re-download or re-copy the file using a reliable method and confirm the file size matches the sender’s copy.
- Test the file in a second JPEG 2000 tool to rule out a single-app parsing limitation.

Recover a deleted or lost .JPM 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
JPM is an image/compound-image format (image/jpm) and is not meant to contain active scripts or macros, but malformed image files can still trigger vulnerabilities in decoders—prefer well-maintained JPEG 2000 tools and keep them updated.
