ICO is the Windows icon format: one .ico file holds the same icon at several sizes, and it is still the classic favicon format. BMP is uncompressed and readable by virtually any program, which some legacy software, embedded devices and Windows tools require.
The largest image stored inside the ICO is used. BMP has no transparency, so transparent areas of the ICO are filled with white. BMP is lossless, so the conversion adds no compression artifacts.
You can drop several ICO files at once and get a ZIP of BMP 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 ICO 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 BMP; several files come as one ZIP archive.
Use the BMP 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.
