JPG to ICO Converter (Favicon Generator)
Create a .ico icon or favicon from a JPG/JPEG image, with every size you need in one file.
How to convert JPG to ICO
- Choose a JPG/JPEG image — a square logo or photo of 512×512 or larger works best. PNG, WebP and SVG also work.
- Tick the icon sizes you need — 16, 32 and 48 are selected by default. Non-square images are centred on a transparent square.

About JPG to ICO
ICO is the Windows icon format used for website favicons. One .ico file can contain several sizes; the browser or operating system picks the best one. This tool stores each size as a PNG image inside the ICO, which every modern browser supports.
Frequently asked questions
Is this JPG to ICO converter free?
Yes, it is free with no sign-up, no watermark and no file limits beyond what your device can handle.
Are my files uploaded?
No. Conversion runs entirely in your browser. Your files never leave your device — you can even go offline after the page loads.
Which sizes should a favicon include?
16×16, 32×32 and 48×48 cover browser tabs and Windows shortcuts. Add 64, 128 and 256 for high-DPI screens and desktop icons. All selected sizes are packed into one .ico file.
How do I add the favicon to my website?
Upload favicon.ico to the root of your site and add <link rel="icon" href="/favicon.ico" sizes="any"> inside <head>. Most browsers also look for /favicon.ico automatically.
Is transparency supported?
Yes. Each icon size is stored as a 32-bit PNG inside the ICO, so transparent backgrounds stay transparent. Non-square images are centred on a transparent square.
Can I convert many files at once?
Yes. Select or drop as many files as you like; each one is converted in turn and gets its own download button.
