SIXEL to SVGZ Converter
Processing entirely on your device — large files may take a moment.
SIXEL is DEC's terminal graphics protocol — raster images rendered inline in VT340/xterm terminals, revived by modern terminal emulators for image display over SSH. Convert SVGZ exactly like SVG — the converter inflates it first — or gzip an SVG back into SVGZ for shipping.
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.
How SIXEL compares to SVGZ
| SIXEL | SVGZ | |
|---|---|---|
| Structure | DEC SIXEL Graphics coder | gzip-wrapped SVG (XML) |
| Compatibility | ImageMagick, specialty tools | All browsers (via header), Inkscape |
| Best for | Legacy and specialty pipelines | Deploying vector assets on the web |

About the SIXEL format
The DEC SIXEL Graphics coder of the ImageMagick set — the terminal-graphics 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 SVGZ format
SVGZ is what every SVG is on a well-configured server: the same XML vector content run through gzip. XML compresses spectacularly, so an SVGZ is typically 70-80% smaller than the SVG it came from — which is why Apache and nginx can serve it transparently with a Content-Encoding header.
Converting SVGZ to PNG or JPG simply inflates it first — the vector content is byte-identical to its SVG parent. The other direction (vectorize a raster, then gzip) produces a deploy-ready compressed asset.
+Strengths
- ✓70-80% smaller than the same SVG
- ✓Transparent to browsers via Content-Encoding
- ✓Full SVG vector fidelity
!Limitations
- −Some tools refuse the double extension
- −Needs gunzip before hand-editing
- −MIME confusion on misconfigured servers
Why convert SIXEL to SVGZ?
There is a concrete reason this conversion exists: Niche format — few modern readers SVGZ sidesteps that — 70-80% smaller than the same SVG If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this SIXEL to SVGZ 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 SIXEL to SVGZ?
No — SVGZ is a lossless format, so every pixel of the converted image matches your original SIXEL 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 SIXEL files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Can I convert several SIXEL 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.
