Frequently asked questions
How do I convert BMP to ICO?
Click “Choose Files” and select your BMP file (or drag it onto the page). ICO is already selected as the output, so just click Convert and download your ICO file when it’s ready.
Will I lose image quality?
No. ICO stores the image without lossy compression, so it looks exactly like the original.
Is it safe to convert BMP files here?
Yes. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.
Is the BMP to ICO converter free?
Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.
Can I convert several BMP files at once?
Yes. Add as many BMP files as you like and convert them in one go, then download them one by one or together as a ZIP file.
