# Convert SVG to ICO.

> Vector-sharp favicons — SVG to a multi-size ICO, locally.

SVG is the ideal favicon source: the vector is rendered fresh for the ICO, so every embedded size comes out sharp. The classic favicon.ico with 16–256 px versions is built entirely in your browser — **your artwork never leaves your device**.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## One vector, every context

Keep the SVG as the master: link it as the modern favicon, ship the generated favicon.ico at your site root as the fallback, and you cover everything from retina tabs to legacy Windows. If the site serves the SVG directly, [Compress SVG](https://compress-pro.com/compress-svg) trims it; for plain raster export, [SVG to PNG](https://compress-pro.com/svg-to-png) renders any size.

## Frequently asked questions

### Why convert from SVG instead of PNG?

The vector is rendered natively before the icon sizes are built, so edges stay crisp — a PNG source has one fixed resolution and every other size is interpolated from it.

### Which sizes go into the ICO?

256, 128, 48, 32 and 16 px in one file — that covers browser tabs, bookmarks, desktop shortcuts and Windows Explorer views. Transparency survives throughout.

### Do I still need an ICO if browsers accept SVG favicons?

Modern browsers do take SVG favicons, but favicon.ico remains the zero-configuration fallback every browser requests on its own — shipping both is the safe setup.

### Is it private?

Yes. The conversion happens entirely on your device — the image is read, re-encoded and saved without ever touching a network. There is no server-side queue, no temporary copy in some bucket, nothing to expire or leak. Want proof? Run one file through, switch your connection off, and run another — it still works.
