JPG to ICO Converter — Free Favicon Maker
The logo you were given is a JPG and you need it as a Windows icon. Convert it here — in your browser, with nothing uploaded anywhere.
Why convert JPG to ICO?
This produces the same multi-size ICO as the PNG route — 16, 32, 48 and 64 px, with 128 and 256 added when the source is big enough — from whatever JPG you already have. It is the quickest path when a client has sent a logo as a photograph attachment rather than as artwork.
The catch worth knowing about
A JPG has no transparency, so the icon will be a solid rectangle including whatever background the JPG had. On a dark taskbar or a browser tab that white block is conspicuous. If the logo needs to sit on a transparent background, you need a PNG version of the artwork, not a conversion.
One tip before you start
JPG compression artefacts around hard edges get worse when the image is scaled down to 16 px. If the logo exists as a PNG or SVG anywhere, start from that instead — this page is for when it does not.

Will I lose quality converting JPG to ICO?
The icon sizes are lossless PNGs internally, so no compression is applied. The images are scaled down to icon dimensions though, and detail that small simply cannot be represented.
Do my JPG files get uploaded?
No. The conversion runs on your device, in the browser tab you are reading this in. You can prove it: disconnect from the internet and convert anyway.
Is it free, and how many JPG files can I do at once?
Free, with no sign-up, no watermark and no daily limit. Up to 200 files per batch, downloadable individually or as one ZIP.
