How to convert SVG to ICO
Drop files into the box, click to browse, or paste from your clipboard. Batch is supported.
Choose a favicon set, a single size, or a multi-size ICO. Adjust quality and transparency.
Grab the .ico, the full favicon package (.zip), or copy the ready-made HTML code.
SVG vs ICO: format comparison
| SVG | ICO | |
|---|---|---|
| Primary use | Vector graphics — logos, icons, UI | Windows icons & favicons |
| Transparency | ✅ Yes (vector alpha) | ✅ Yes (32-bit BMP or PNG) |
| Animation | ✅ SVG can animate (CSS/SMIL) | ❌ Static only (first frame is used) |
| Resolution | ✅ Infinite — scales to any size | ⚠️ Fixed 16–256px grid |
| Where it runs | Browsers, design tools (Figma, Illustrator) | Windows, browsers (favicon), apps |
| Why convert | — | SVG can't be used as a favicon.ico or Windows icon directly |
Convert SVG to ICO at 256×256 or any other size
The ICO format can store icons from 16×16 (small browser tab) to 256×256 (Windows 10/11 high-DPI). Instead of hunting for an SVG that happens to be the right size, use the size presets here: the converter rasterizes your vector to 16, 32, 48, 64, 128, 180, 192 or 256 pixels — or type any custom size. A 256×256 SVG to ICO conversion is the most common request because that is the largest size Windows and macOS recognize natively, and it is automatically downscaled into every smaller size inside the same .ico file.
Lossless and high-quality SVG to ICO output
ICO is a bitmap format, so your vector SVG is rasterized (converted to pixels) the moment it is exported — the output can never be "infinite resolution". What you control here is the quality of that rasterization: Lossless stores the rendered PNG data inside the ICO with no further compression, High uses high-quality resampling for sharp edges, and Balanced is the fastest. Because SVG scales cleanly, render at a large size first (256×256) so every smaller icon in the set inherits crisp edges. After conversion, inspect the preview grid — you can judge legibility at every size before downloading.
Why is my icon blurry at 16×16?
Small sizes lose detail because the source image is downscaled. Best practice: start from a large, simple shape (a 256×256 icon with high contrast and bold shapes survives 16×16 best). The preview grid in the result panel lets you check this before you commit to the download.
Frequently asked questions
Is it free to convert SVG to ICO?
Yes — completely free, with no limits, no registration and no watermark. This page has no paywall and no file-count restrictions for normal use.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your files never leave your device — you can even unplug your internet after opening the page and the tool still works.
Can I use the output as a website favicon?
Yes — that is the main use case. Choose the "Favicon set" mode to get favicon.ico, PNG icons at 16/32/180/192px, apple-touch-icon, site.webmanifest and the HTML code to paste into your site's head. Browsers request multiple sizes, so the full set gives the sharpest result everywhere.
What sizes should a favicon be?
Minimum you need: favicon.ico (16+32+48 inside one file), favicon-32x32.png and favicon-16x16.png. For best results on all platforms add apple-touch-icon.png (180×180), android-chrome-192x192.png and android-chrome-512x512.png. The favicon-set mode generates all of these automatically.
My SVG turns into a blank or 0×0 icon — why?
Some SVG files only contain a viewBox but no explicit width/height attributes, so the browser has no intrinsic size to render. The converter needs a known size to rasterize against. Fix: open the SVG in a text editor and make sure the root <svg> tag includes both, e.g. <svg width="512" height="512" viewBox="0 0 512 512">. Then re-upload.
Is the output still a vector? Will gradients survive?
No — ICO is a bitmap format, so the SVG is rasterized to pixels during conversion. The rendered result keeps gradients, strokes and filters, but at 16×16 most fine detail disappears. Design rule of thumb: for small icons, use bold solid shapes with high contrast; reserve gradients and thin strokes for the 128px+ sizes.
Can an animated SVG be converted?
ICO is a static format. An animated SVG (CSS or SMIL) is rendered in its initial state, so you get the first frame as a still icon. Animated favicons are not supported by modern browsers anyway — a static, high-contrast icon is the right choice.
