QOI to SVG Converter
Processing entirely on your device — large files may take a moment.
QOI (Quite OK Image) is a 2022 lossless format with a ~200-line spec — PNG-class simplicity that compresses similarly fast. Because only browsers and design tools handle SVG natively, exporting it to PNG or JPG makes the artwork usable in Office documents, photo editors and ordinary apps.
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 QOI compares to SVG
| QOI | SVG | |
|---|---|---|
| Compression | Lossless (RLE/delta) | Lossless (gzip-able text) |
| Transparency | Supported | Native (it is just geometry) |
| Animation | Not supported | SMIL, CSS, JS |
| Metadata | None | Arbitrary XML metadata |
| Best for | Hobby engines, lossless simplicity | Icons, logos, charts, illustration |

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 SVG format
SVG (Scalable Vector Graphics) is the W3C's XML-based vector format. Instead of pixels, it stores shapes — paths, circles, polygons, text — as math, which means an SVG logo is a few kilobytes and stays perfectly sharp from a 16-pixel favicon to a billboard. Browsers render it natively, CSS can restyle it, and it scales with zero quality decisions to make.
It is the wrong tool for photographs — vectorizing a photo produces enormous, slow files. It is also worth remembering that SVG is executable XML: files from untrusted sources can carry scripts, so sites typically sanitize uploads. For icons, logos, charts and flat illustration, nothing else comes close.
+ Strengths
- ✓Infinitely scalable with zero quality loss
- ✓Tiny files for icons and geometric art
- ✓Styleable and animatable with CSS and JavaScript
- ✓Text stays selectable and searchable
! Limitations
- −Unsuitable for photographs — files explode in size
- −Complex hand-drawn illustrations can grow heavy too
- −Untrusted SVG can embed scripts and needs sanitizing
Why convert QOI to SVG?
Converting makes sense where the strengths of SVG meet what QOI cannot give you. Infinitely scalable with zero quality loss Meanwhile Almost no viewer support One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this QOI to SVG 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 SVG?
No — SVG 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.
Will transparent areas survive the conversion to SVG?
Transparency is kept whenever SVG 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.
