Why convert JPG to ICO?

Every website needs a favicon, the small icon in the browser tab, and .ico is the most broadly compatible format for it, including for older browsers. If your logo or image is a JPG (also written JPEG, the same format), converting it to ICO turns it into a proper favicon file. A good favicon bundles several sizes so it stays crisp from a 16-pixel tab to a large bookmark tile. This tool lets you pick which sizes to include, with sensible defaults already selected. One thing to know: JPG cannot store transparency, so a JPG-based favicon will have a solid (usually rectangular) background; if you need the icon to blend into the tab, start from a PNG instead. For the sharpest result, use a square JPG. The whole conversion runs in your browser, and nothing is uploaded.

how to make a favicon from a jpg

Upload your JPG, tick the icon sizes you want bundled in (16 to 256 px), and download a single .ico favicon. JPG has no transparency, so the icon is opaque; for a transparent favicon start from a PNG. It all happens in your browser, so the file is never uploaded.

How to convert JPG to ICO

  1. 1Drop your JPG in, or tap Upload. A square image works best.
  2. 2Tick the icon sizes to bundle in (16, 32, 48, 64, 128, 192, 256 px).
  3. 3Click Convert to build the multi-size .ico.
  4. 4Download your .ico favicon. Nothing is uploaded.

Why a favicon needs an ICO

A favicon is the small icon in a browser tab, and .ico is the most broadly compatible format for it, including older browsers. The trick is that a good favicon holds several sizes at once so it looks crisp everywhere. Convert JPG to ICO to bundle the sizes you need into one file. Because JPG has no transparency, the favicon will be opaque; choose PNG to ICO instead when you want the icon to blend into any tab colour.

Frequently asked questions

Will my JPG favicon have a transparent background?
No. JPG cannot store transparency, so the icon is opaque. If you need a see-through favicon, start from a PNG instead. PNG to ICO
Which sizes should my favicon include?
16 and 32 px cover browser tabs, while larger sizes like 192 and 256 px serve bookmarks and app icons. The tool pre-selects a solid default set, and you can adjust it.
Should my JPG be square?
Yes. Favicons are square, so a square JPG gives the cleanest result. A non-square image is fitted to a square.
Do I need multiple sizes in one file?
It helps. A multi-size .ico stays crisp from a tiny tab to a large bookmark tile, which a single size cannot.
Need to square or crop the JPG first?
