Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.

It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many ICO files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting ICO to BMP reduce quality?
No. Both formats are lossless, so every pixel is kept.
Does BMP keep transparency?
BMP doesn't support transparency, so transparent areas are filled with a background color you can choose.
