Why Convert JPG to ICO?
If you have a logo or image saved as JPG and need to use it as a website favicon or application icon, you’'ll need to convert it to ICO format. ICO is the universal standard for favicons recognized by all browsers.
| Feature | JPG | ICO |
|---|---|---|
| Purpose | Photos, web images | Favicons, app icons |
| Transparency | No | Yes |
| Multiple sizes | No | Yes (embedded) |
| Compression | Lossy | Lossless |
| Browser use | As content image | As favicon |
| Best for | Photographs | Browser tabs, bookmarks |
Note that JPG does not support transparency, so your resulting ICO will have an opaque background. For favicons with transparent backgrounds, start with a PNG file using our PNG to ICO converter.

Tips for Best Results
- Use a square image — Crop your JPG to a 1:1 aspect ratio before converting for the best results
- Simple designs — Favicons display at tiny sizes (16x16 to 48x48 pixels), so detailed photos won’'t look good
- No transparency — JPG doesn’'t support transparency; the background will remain solid in the ICO file
- Want transparency? — First convert your JPG to PNG, remove the background, then use PNG to ICO
