MIFF to XV Converter
Processing entirely on your device — large files may take a moment.
Magick Image File Format and XV Thumbnail exist for different jobs: 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. Convert to XV thumbnails for legacy UNIX galleries.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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.
+Strengths
- ✓Lossless with full channel fidelity
- ✓Multi-frame and rich metadata support
- ✓Native to ImageMagick pipelines
!Limitations
- −Large files (little compression)
- −Unsupported outside ImageMagick
About the XV format
The XV Thumbnail coder of the ImageMagick set — the unix-gallery format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
Why convert MIFF to XV?
Think of it as moving your file to the container that fits the job. Large files (little compression) XV works differently: Written natively by ImageMagick If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this MIFF to XV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting MIFF to XV?
No — XV is a lossless format, so every pixel of the converted image matches your original MIFF file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your MIFF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to XV?
Transparency is kept whenever XV actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
