How to convert JPEG to ICO
- Add your .JPEG file - drop it in the box above or click to browse.
- Convert it to .ICO in a few seconds.
- Download your new .ICO file.
What to expect
- Photos scale poorly to icon sizes - a photograph at 32×32 pixels will look muddy; flat logos and simple illustrations work far better.
- ICO is a container that can hold multiple sizes (16, 32, 48, 256 px) in one file; most online tools produce only one size, while GIMP lets you pack all sizes at export.
- JPEG has no transparency - if you need a see-through background in the icon, remove it manually in an editor such as GIMP before exporting.
Frequently asked questions
What size should I use for a Windows application icon?
256×256 covers modern high-DPI displays. For full compatibility with older Windows versions and installer dialogs, pack 256, 48, 32, and 16 px into one
.ico file using GIMP.What size should I use for a favicon?
A single 32×32 layer works in all current browsers; some developers also include a 16×16 layer in the same file for legacy support.
Why does IrfanView not show ICO in the Save As list?
The ICO export plugin is part of IrfanView's separate PlugIns package - download and install it from irfanview.com alongside the main program.
Will converting to ICO fix JPEG compression artifacts?
No - any compression artifacts already in the JPEG carry over to the icon as-is; the conversion does not improve image quality.
