BMP is the uncompressed Windows bitmap format: simple and readable everywhere, but files are very large. ICO is what Windows and browsers expect for icons and favicons, with several sizes packed into one file.
The icon includes every size from 16×16 up to 256×256 px that fits your image, all in one .ico file. ICO is lossless, so the conversion adds no compression artifacts.
You can drop several BMP files at once and get a ZIP of ICO files. Each file can be up to 20 MB; there's no daily limit and no signup, and uploads are deleted from our servers within 1 hour.
Drag BMP files onto the page or click to choose them. You can add several at once.
Conversion starts on its own — there are no settings to pick. Most files are ready in a few seconds.
A single file downloads as ICO; several files come as one ZIP archive.
Use the ICO right away: open it, share it or upload it wherever you need it.
Your uploads and results are deleted from our servers within 1 hour.
