Quick answer: To convert ICO to BMP, add the ICO file to the iHateFiles ICO to BMP converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. A straight swap between two raster formats, at full resolution.
Should you convert ICO to BMP?
A safe conversion: ICO and BMP are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
ICO and BMP are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the ICO. Renaming a PNG to favicon.ico works in most browsers and then fails in the one that matters. A real ICO bundle avoids the argument entirely.
About the BMP. The file size surprises people. There is no compression to speak of, so the size depends only on the dimensions, not on how complicated the image is.
How to convert ICO to BMP
- Add your ICO file. It is read from your disk and stays there.
- Check the settings. The output format is already set to BMP.
- Press convert and the BMP file is saved back to your device.
Questions
How do I convert ICO to BMP?
Open this page, add your ICO file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this ICO to BMP converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to BMP lose quality?
BMP is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several ICO files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
