This conversion is occasionally necessary and usually not the right choice, which is worth saying plainly before you make it. Icons exist to sit on top of other things - a taskbar, a browser tab, a document background - and the property that lets them do that is transparency. JPEG has no transparency at all, so every transparent pixel in the icon becomes solid white, and the result is an image with a white rectangle around it that will look wrong anywhere except on a white page. There are legitimate reasons to want one anyway: a system that accepts only JPEG, a document template that rejects PNG, a print workflow with a fixed format list. When one of those applies this does the job correctly. When it does not, the PNG converter is almost certainly what you actually want.
Shape and export choices
- The ICO container is decoded and the browser selects one of the images it holds, generally the largest.
- A canvas is filled with white before the icon is drawn, because JPEG cannot record transparency and a colour must be chosen.
- The result is encoded as JPEG at a high quality setting, at the dimensions of the selected image.
- Anti-aliased edges blend into the white background, which is why the outline may look slightly haloed against any other colour afterwards.
- No resizing occurs; the output matches whichever size the decoder chose from the container.

If the page is white the white background is invisible, and JPEG is widely accepted by print workflows.
Check the image before download
- Transparency becomes white and cannot be undone. This is the main reason to prefer PNG for icons.
- Icons are small and full of hard edges, which is the weakest case for JPEG. Expect visible artifacts around the outlines.
- The JPEG will often be larger than the ICO, because icons are tiny and JPEG carries fixed overhead.
- Only one size is extracted from the container, chosen by the browser rather than by you.
- For anything that will sit on a coloured background, this conversion produces a result that looks broken. Use PNG or WebP instead.
Questions about ICO to JPG
Why does my icon have a white box around it?
Because JPEG cannot store transparency, so the transparent area had to be filled with a colour. Use the PNG converter to keep the cut-out.
Why does it look blocky at the edges?
JPEG compresses sharp transitions poorly, and icons are almost entirely sharp transitions. PNG avoids this completely.
Which size is used?
Whichever the browser selects from the container, usually the largest available.
Should I use this at all?
Only when the destination refuses PNG and WebP. For every other case one of those is better.
