How to open .WMF files on iOS
To open .WMF files on iOS, iOS support for WMF is inconsistent; if it won’t open in your viewer apps, convert the file on a desktop (e.g., with ImageMagick) to PNG or PDF and then transfer it back to your device.
Step-by-step instructions
- iOS support for WMF is inconsistent; if it won’t open in your viewer apps, convert the file on a desktop (e.g., with ImageMagick) to PNG or PDF and then transfer it back to your device.
Common issues
The file won’t open or shows as an unknown format
WMF is a Windows-oriented metafile format; many viewers (especially on mobile or some non-Windows setups) don’t include a WMF renderer by default.
- Convert the .wmf to PNG or PDF using ImageMagick, then open the converted file.
- If you’re on Linux and file type detection is wrong, check that your system’s shared MIME database recognizes WMF; regardless, conversion is usually the quickest workaround.
Rendering looks wrong (missing elements, odd fonts, or incorrect scaling)
WMF stores drawing records that depend on how the renderer interprets GDI-style operations; different renderers and conversion pipelines can produce different results.
- Try converting to multiple outputs (e.g., PNG and PDF) to see which preserves appearance best.
- If the WMF contains text, expect font substitution; consider converting on a Windows machine if fidelity is critical.
Conversion fails or produces an empty/blank output
Some WMF files use records or constructs that a specific converter build does not handle well, or the file may be damaged/truncated.
- Re-run conversion with a different output format (PNG vs PDF) using ImageMagick and compare results.
- If possible, obtain the WMF again from the original source/export step to rule out corruption.

Recover a deleted or lost .WMF 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
Treat WMF as potentially risky when received from untrusted sources: it is a complex, record-based graphics format that requires a parser/renderer, and historical WMF handling has been security-sensitive in general due to the complexity of metafile processing.
