XV to SIXEL Converter
Processing entirely on your device — large files may take a moment.
XV Thumbnail and DEC SIXEL Graphics exist for different jobs: XV is the thumbnail format of John Bradley's classic XV image viewer on UNIX — a compact 33-byte header plus raw thumb data. Convert an image to SIXEL to preview it inside a terminal session.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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 XV to SIXEL?
Converting makes sense where the strengths of SIXEL meet what XV cannot give you. Written natively by ImageMagick Meanwhile Niche format — few modern readers One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this XV to SIXEL 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 SIXEL?
No — SIXEL 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.
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 XV 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 SIXEL?
Transparency is kept whenever SIXEL 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.
