XV to MAT Converter
Processing entirely on your device — large files may take a moment.
Convert MAT image arrays to PNG for reports and previews. If your files are still in XV format, this page is the shortcut: XV is the thumbnail format of John Bradley's classic XV image viewer on UNIX — a compact 33-byte header plus raw thumb data.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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
About the MAT format
MAT is the workspace format of MATLAB and its open-source sibling Octave. Image data shows up inside MAT files as numeric arrays — simulation frames, sensor captures, processed microscopy — usually alongside the variables and metadata a research script produced with them.
Converting the image arrays inside a MAT file to PNG makes them viewable and shareable without MATLAB — useful for reports, papers and collaborations where colleagues do not have a MATLAB license.
+Strengths
- ✓Carries numeric precision end to end
- ✓Pairs image data with research variables
- ✓Octave compatibility (open tooling)
!Limitations
- −Requires MATLAB/Octave to open
- −Not an image container by design
Why convert XV to MAT?
Think of it as moving your file to the container that fits the job. Niche format — few modern readers MAT works differently: Carries numeric precision end to end If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this XV to MAT 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 XV to MAT?
No — MAT is a lossless format, so every pixel of the converted image matches your original XV file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to MAT?
Transparency is kept whenever MAT 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.
Can I convert several XV files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
