QOI to SVGZ Converter
Processing entirely on your device — large files may take a moment.
Convert SVGZ exactly like SVG — the converter inflates it first — or gzip an SVG back into SVGZ for shipping. If your files are still in QOI format, this page is the shortcut: QOI (Quite OK Image) is a 2022 lossless format with a ~200-line spec — PNG-class simplicity that compresses similarly fast.
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 QOI format
QOI (Quite OK Image, 2021) is a lossless format defined in one short specification document: a stream of simple run-length and delta ops over linear pixels. An encoder fits in 300 lines, decodes faster than PNG, and compresses comparably for photographic content.
It has found a home in emulators, demoscene projects and hobby engines — anywhere people want images without a codec dependency. Viewers rarely support it, so converting QOI to PNG is the way to bring these files into normal tools.
+ Strengths
- ✓Radically simple spec (~200 lines)
- ✓Lossless with fast decode
- ✓No patent or licensing questions
! Limitations
- −Almost no viewer support
- −Larger than modern codecs for many images
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 QOI to SVGZ?
There is a concrete reason this conversion exists: Almost no viewer support 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 QOI 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 QOI to SVGZ?
No — SVGZ is a lossless format, so every pixel of the converted image matches your original QOI file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several QOI 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.
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 QOI files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
