Do you accept .jpeg as well as .jpg?

Yes. Both extensions and image/jpeg are accepted. The jpeg-to-ico URL redirects here.

Can I keep a transparent background?

Not from JPEG. Convert a PNG or WebP with alpha, or design in the favicon generator.

What sizes are in the ICO?

16×16 and 32×32, written as PNG-compressed ICO entries.

ToolsJPG to ICO

JPG to ICO converter

Turn a .jpg or .jpeg into a favicon.ico. JPEG has no alpha channel, so any “transparent” look in the source is already flat; we still letterbox into a square and pack 16×16 and 32×32 PNG frames inside the ICO.

JPEG and opacity

Unlike PNG or WebP, JPEG cannot store transparency. Soft edges or cutouts in a JPG are already baked into the pixels (often against white or a busy background).

Photos as favicons

Busy photos read poorly at 16×16. Prefer a simple mark or convert a cropped logo. For text or icons from scratch, use the generator.
