How to open .IMI files on Mac
To open .IMI files on Mac, transfer the .IMI to a device running ImageMeter and import it in ImageMeter to continue editing.
Step-by-step instructions
- Transfer the .IMI to a device running ImageMeter and import it in ImageMeter to continue editing.
- For basic inspection only, use Archive Utility or another ZIP tool to open the container and extract embedded images (editable measurement data is typically ImageMeter-specific).
Common issues
The file opens as a generic ZIP or shows only images (measurements missing)
An .IMI is a ZIP container; generic archive/image tools can extract or preview the underlying images but usually cannot interpret ImageMeter’s measurement/annotation layer.
- Open/import the .IMI in ImageMeter to see and edit the measurements/annotations.
- If you only need the base photo/PDF, extract the images with a ZIP tool and open them in a standard viewer.
Cannot import/open the .IMI in ImageMeter
The file may be incomplete, corrupted, or not actually an ImageMeter IMI (misnamed extension).
- Re-download or re-transfer the file and try importing again (transfer interruptions can corrupt ZIP containers).
- Confirm it is an ImageMeter export (“ImageMeter Image (IMI)”) from the sender and not a different file type renamed to .imi.
Wrong app association when double-clicking .IMI
Because the format is ZIP-based, operating systems may associate .IMI with archive utilities instead of ImageMeter (or may not recognize it at all).
- Open the file from within ImageMeter using its import/open function rather than relying on double-click behavior.
- On Linux/desktop environments, consider adding an association for application/vnd.imagemeter.image+zip so the system recognizes the type.
Security note
.IMI is a ZIP container (application/vnd.imagemeter.image+zip). Treat it like any archive: it can contain multiple embedded files, so only open or extract it if you trust the source.
