What this tool does

It turns a SVG image into a favicon package: a multi-size favicon.ico plus the PNG sizes, web manifest and HTML snippet that browsers, Android and iOS look for. SVGs without a declared width/height are rasterised from their viewBox (or at 1024 px if there is none).

About SVG

SVG is not a grid of pixels at all: it is an XML text file describing shapes, paths and text, which the viewer draws at whatever size is needed. That is why a logo as SVG stays razor-sharp on a billboard and a watch face alike, and why a 5 KB SVG can replace a 500 KB PNG. It is good for logos, icons, illustrations, diagrams and anything that must scale or be edited as shapes; less good for photographs — a photo can only be "traced" into vector shapes, which gives a posterised, painterly result, not the original. All browsers and design tools; some CMSs, social networks and office programs refuse SVG uploads (and it is not safe to accept from strangers because it can contain scripts).

About ICO

ICO is the Windows icon container: one file holding the same image at several sizes (16, 32, 48 px…), so the system can pick the right one. It is what browsers still look for at /favicon.ico, and what Windows uses for program and shortcut icons. It is good for favicons and Windows application icons — nothing else; less good for any other use; it is a container, not a general image format. Browsers and Windows; most image editors can open but not all can save it.

What changes going from SVG to ICO

  • Transparency is kept. Both formats support an alpha channel.
  • Animation is dropped. ICO is a still format; you get the first frame.
  • Metadata: EXIF (camera, date, GPS) is not carried over — the browser decodes pixels, not tags. That is a privacy plus for sharing and a minus if you rely on dates in the file.

Best possible source

An SVG logo is the ideal favicon source: it is rasterised cleanly at every size (16, 32, 48, 180, 192, 512 px) instead of being shrunk from one bitmap. You get favicon.ico, all the PNGs, a web manifest and the HTML to paste into <head>.

How to make a favicon from SVG

  1. Drop the SVG file on the panel above or click to choose it.
  2. Check the preview of each size; non-square images are padded, not stretched.
  3. Download. The file is named after the original with a .ico extension (inside a ZIP with the PNGs and HTML).

Frequently asked questions

Is my SVG file uploaded?

No. The page is static and has no upload endpoint; your browser does the work on your own device and the result is saved straight back to your disk. The site's Content-Security-Policy only allows it to talk to its own origin, so it cannot send your file anywhere even by accident. Load the page, disconnect from the internet, and it still works.

Does SVG to ICO lose quality?

The icon sizes are rendered from your image with high-quality downsampling; at 16 px any image loses detail, which is why simple, bold logos make the best favicons.

Will transparency survive?

Yes — ICO supports an alpha channel, so transparent areas of the SVG stay transparent in the output. Icons with transparent corners render properly in tabs and on the desktop.

Is it free? Any limits or watermark?

Free, no account, no watermark, no daily quota. Because nothing runs on our servers there is nothing to meter. The only limits are your device's memory — anything up to roughly 50 megapixels is fine on a modern phone or laptop.

Can I do several files at once?

One file at a time at the moment — drop the next one as soon as you have downloaded the first. Batch processing with a ZIP in and out is planned.

Does it work on my phone?

Yes — iPhone, iPad and Android browsers all run it. Large files take a few seconds longer on a phone than on a laptop.
