QUICK ANSWER
Is it possible to convert QOI to BMP?
Yes - QOI converts to BMP.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

The quickest route is ImageMagick: magick input.qoi output.bmp decodes the QOI and writes an uncompressed bitmap. The pixels are preserved exactly, but the resulting .bmp is much larger because BMP stores data without QOI's compression.

Also to BMP: XPM · PPM · PGM

Why convert QOI to BMP?

People convert QOI to .bmp when a program or embedded display expects a plain uncompressed bitmap, since BMP stores raw pixels that are trivial to read without a decoder.

How to convert QOI to BMP

ImageMagick OPEN-SOURCE

QOI is supported natively in ImageMagick 7.1.0-20 and later; run magick input.qoi output.bmp to decode and write the bitmap.

XnView MP FREE

Install the pfusik qoi-fu plugin, open the .qoi, then use File > Export (or batch convert) and pick BMP as the output format.

GIMP OPEN-SOURCE

Add the qoi-fu QOI plugin, open the .qoi, then choose File > Export As and save with a .bmp extension.

.QOI Quite OK Image Format

A .qoi file is a Quite OK Image, a lossless raster image saved in an open format created by Dominic Szablewski in 2021 as a much faster alternative to PNG. It stores 24-bit RGB or 32-bit…

.BMP Windows Bitmap Image

A BMP file is a Windows Bitmap - a simple, usually uncompressed raster image developed by Microsoft. Every major OS and image viewer opens it with no extra software (double-click works).…

Quality & what to watch

  • 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 .qoi directly.

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.
