How to convert QOI to BMP
- Add your .QOI file - drop it in the box above or click to browse.
- Convert it to .BMP in a few seconds.
- Download your new .BMP file.
What to expect
- BMP is uncompressed, so the output file is typically several times larger than the QOI source.
- Standard 24-bit BMP has no alpha channel, so QOI transparency is flattened unless you save a 32-bit BMP that your target actually supports.
- Older ImageMagick builds predate QOI support; you need version 7.1.0-20 or newer to read
.qoidirectly.
Frequently asked questions
Does converting QOI to BMP lose quality?
No, both are lossless, so the RGB pixels are preserved exactly. The trade-off is file size, not image quality.
Why is the BMP so much bigger?
BMP stores raw uncompressed pixels while QOI compresses them. The same image therefore takes far more space as a bitmap.
What happens to transparency?
A standard 24-bit BMP drops the alpha channel. Save a 32-bit BMP if you need to keep transparency and your software supports it.
Which tool is easiest for many files?
ImageMagick handles batches from the command line, and XnView MP offers a graphical batch-convert dialog.
