About JPG to ICO Converter
This converts a photograph or a flat JPG image into the ICO container that browsers and Windows use for icons. It works, and for a photo-based avatar or a logo already sitting on a solid background it is the quickest route to a favicon.ico — but it comes with one limitation that PNG to ICO does not have.
Add up to 15 JPG or JPEG files (5MB each) and click Convert; ICO is already selected. The longest side is capped at 256px, the ICO maximum. Square sources give the best result. Download each icon or take them all as a ZIP.
The limitation is transparency, and it matters more than people expect. JPG has no alpha channel, so your icon will be an opaque rectangle — in a browser tab that shows as a visible square block, and it looks especially wrong against a dark-mode tab strip. If your logo is supposed to have a transparent background, remove the background first, save as PNG, and use the PNG to ICO converter instead. Beyond that, remember the icon is displayed at 16–32px: simplify hard before converting, because photographic detail is unreadable at that scale.

Frequently Asked Questions
Should I use a JPG or a PNG as my favicon source?
PNG is generally better for logos and icons with text or hard edges, since JPG's lossy compression can slightly soften fine details at small sizes. JPG works fine for photo-style icons.
What size should my JPG be for a good favicon?
Use a square image at least 256×256px. ICO output caps out at 256px on the longest side, and non-square source images get stretched to fit.
Can ICO store transparency from my JPG?
JPG itself has no transparency to carry over, so the icon background will be whatever's in the source photo — use a PNG source if you need a transparent icon background.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser.
