Convert ICO files to SVG free in your browser — no signup, no install, and the file is never uploaded to a server. SVG keeps full quality with no further loss.
Add your ICO file
Drag the ICO file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm SVG as the output
SVG is already selected as the output format on this page. You can set the output width and height. Quality stays untouched because this format is lossless.
Run the conversion
Press the convert button. A single image is usually done before you finish reading this sentence.
Download the SVG file
When it finishes, download the SVG file. Converting multiple files gives you the option to download them together as a ZIP.
The format used for Windows icons and website favicons, capable of holding several sizes from 16x16 up to 256x256 inside a single file.
A vector format that describes artwork as mathematical shapes rather than pixels. It stays sharp at any zoom level, and because the file is text you can edit it in code.
Yes. ICO to SVG conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the ICO file never leaves your device. That is also why it works without an internet connection once the page has loaded.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
