Convert any image to a multi-size .ico favicon — 16×16 through 256×256 in one file
Tips
- Start with a square transparent PNG for best results at small sizes
- Use the background remover first to make your logo transparent
- Most browsers use the largest size available — include 256×256 for modern browsers
- Include 16×16 for browser tabs and 32×32 for Windows taskbar icons
How it works
- Drop a PNG or JPG source image — square images work best (the tool will centre and pad non-square inputs)
- Select which ICO sizes to include — 16×16, 32×32, 48×48, 64×64, 128×128, 256×256
- Download the .ico file — a single file containing all selected sizes for Windows, browsers, and desktop shortcuts
Frequently asked questions
Which sizes should I include in my favicon?
At minimum: 16×16 (browser tab) and 32×32 (taskbar / bookmark). Add 48×48 for desktop shortcuts and 256×256 for high-DPI displays. For web favicons, 16 and 32 are essential.
Does the input image need to be square?
No. The tool centres non-square images and pads with transparency. For best results, start with a square PNG so nothing is cropped.
Can I use ICO files for anything other than favicons?
ICO files are used for Windows desktop icons (.exe, .lnk shortcut icons), taskbar icons, and folder icons. For web only, you can also use a 32×32 PNG as a favicon with <link rel="icon" type="image/png">.
Why it's different
Multi-size .ico favicon creation entirely in your browser — 16×16 to 256×256 packed in one file. No upload, no server, your logo stays private.
