MIFF File Format

Magick Image File Format category

MIFF is ImageMagick's own intermediate format — a lossless raster container that preserves every channel and profile exactly as the engine sees it, used to chain command-line pipelines.

Typical use: Convert images to MIFF when a downstream ImageMagick pipeline expects it, or MIFF to PNG/JPG for viewing.

About the MIFF format

MIFF is ImageMagick's own interchange format — a lossless raster container designed to carry exactly what the engine has in memory: every channel, an optional color profile, per-image properties and even multiple frames in one file. Command-line pipelines use it as the glue between successive ImageMagick operations.

Outside ImageMagick tooling almost nothing opens MIFF. Convert MIFF to PNG or JPG to hand pipeline intermediates to people, or into MIFF when feeding an ImageMagick chain that expects the format.
