Free converter
Anyfile converts a Windows icon to a BMP image for free, right in your browser: the file is never uploaded.
Files are converted in your browser and never uploaded. By using Anyfile you agree to the Terms of Use.
| Quality | Nothing lost: BMP keeps every pixel |
|---|---|
| Transparency | Transparent areas are filled with white |
| Colour depth | Saved at 8 bits per channel |
| File size | Usually larger: BMP compresses less tightly than ICO |
When to use BMP: Older Windows software, simple paint programs and tools that expect raw, uncompressed pixels.
.ico
The Windows icon format. One file bundles the same picture at several sizes, such as 16, 32 and 256 pixels square, so the system can pick the right one.
Website favicons and application icons on Windows.
Opens in browsers, File Explorer, Photos, Preview, GIMP
About ICO files.bmp
Microsoft’s bitmap format from the early days of Windows. It usually stores pixels uncompressed, so quality is exact but files are large.
Older Windows software, simple paint programs and tools that expect raw, uncompressed pixels.
Opens in Paint, Photos, Preview, most image editors and browsers

Need to change it first? Open the photo editor
Drop your ICO file on this page, or choose it. Anyfile converts it on your device in a moment and the BMP downloads straight away. To change it first, open it in the photo editor.
No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.
BMP can’t hold transparency, so they’re filled with white.
Yes. Drop them together and you get one ZIP with every BMP inside.
