About ICO
ICO (Windows Icon, 1985) is the icon format used by Windows and by website favicons. One ICO file can hold several sizes (16×16 up to 256×256), so the right one is shown in tabs, desktops and taskbars.
Best for: website favicons and Windows app icons. Used by all browsers for favicons and by Windows for icons.
Frequently asked questions
Which formats can I convert to ICO?
JPG, PNG, HEIC/HEIF, WebP, AVIF, GIF, BMP, TIFF, SVG, ICO, Photoshop PSD and camera RAW files (CR2, CR3, NEF, ARW, DNG, ORF, RW2, RAF and more). Mix different formats in one batch.
Are my files uploaded?
No. Everything is converted in your browser on your own device. Nothing is sent to a server.
Is there a limit?
No. Convert as many files as you like, for free, without an account.
What size should a favicon be?
Modern sites use a 32×32 favicon, with 16×16 for older browsers and larger sizes for shortcuts. This converter puts 16, 32, 48, 64, 128 and 256 pixel versions into one ICO file, so you only need one. Use a square image for the best result.
Will I lose quality converting to ICO?
No. ICO is lossless, so the converted image keeps every pixel of the original.
