Turn your ICO images into SVG right in the browser — this tool will shrink each file and hand it back in seconds, with nothing uploaded to any server. ICO is the Windows icon and favicon format, holding one or more small square images up to 256×256. SVG is a vector format built from mathematical paths, so it scales to any size without losing sharpness. The conversion keeps your image faithful while switching it into the SVG container. Free, private, unlimited, and watermark-free.
How to Convert ICO to SVG
Add your ICO files
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to SVG
Press Convert. SVG is lossless, so every pixel is preserved exactly.
Download
Save each SVG file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert ICO to SVG?
The main reason is logos and icons that must stay crisp at every size. ICO excels at favicons and Windows application icons, but when you need pixel-perfect quality, SVG is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
SVG is a lossless format, so the conversion preserves your image exactly — no detail is discarded in the SVG encoding itself.
A note on file size
Expect the SVG file to be noticeably smaller than your ICO.

Tips & Things to Know
Check the file size after converting
Expect the SVG file to be noticeably smaller than your ICO. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Transparency is preserved
Both formats support an alpha channel, so any transparent regions in your ICO stay transparent in the SVG — nothing is flattened onto a solid background.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your ICO files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
The conversion is faithful
SVG is lossless, so every pixel is preserved exactly as it was in your ICO, meaning you do not have to worry about settings — just convert and download.
