GRAY to SIXEL Converter
Processing entirely on your device — large files may take a moment.
Convert an image to SIXEL to preview it inside a terminal session. If your files are still in GRAY format, this page is the shortcut: GRAY is the single-channel spelling of raw grayscale dumps — the same unformatted luminance bytes the GRAYA variant adds alpha to.
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 GRAY format
The Grayscale + Alpha (raw) coder of the ImageMagick set — the raw-pixels 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 GRAY to SIXEL?
There is a concrete reason this conversion exists: Niche format — few modern readers SIXEL sidesteps that — Written natively by ImageMagick If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this GRAY 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 GRAY to SIXEL?
No — SIXEL is a lossless format, so every pixel of the converted image matches your original GRAY file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several GRAY 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.
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.
