Learn more in the docs →Why ICO?
Instant Favicon
Turn a JPG photo or logo into a browser-tab favicon in one click.
Multiple Resolutions
Bundle 16 to 256px versions into one .ico so every browser picks the right fit.
No Transparency Needed
JPG has no alpha channel, so backgrounds stay solid — ideal for logos on a flat color.
Frequently Asked Questions
Can JPG have transparency in the ICO?
No. JPG has no alpha channel, so the converted icon keeps a solid rectangular background. For a transparent favicon, convert from a PNG instead.
What size favicon do browsers use?
Most browsers show the 16×16 or 32×32 entry in the tab; larger sizes are used for bookmarks, home-screen icons, and high-DPI displays.
Will JPG compression artifacts show up in the icon?
Yes — if the source JPG is heavily compressed, those artifacts get resized into the icon too. Start from the highest-quality JPG you have.
Where do I put the .ico file?
Drop it in your site root as favicon.ico, or reference it explicitly with a tag in your HTML head.
