Convert AVIF to BMP Online Free & Fast
Turn your AVIF images into BMP files in seconds. No installs, no software just upload, convert and download.
This tool converts AVIF images into BMP format directly in your browser. Quality depends on how your original AVIF was encoded AVIF can be lossy or lossless, and the file extension doesn't reveal which, so a lossless AVIF converts losslessly, while a lossy AVIF simply carries its existing quality into an uncompressed file rather than recovering anything. Expect the biggest jump in file size of any conversion on this site: BMP stores images uncompressed, and AVIF is the most space-efficient format here, so the size increase is more dramatic than converting from WebP or PNG. Transparency support in BMP is inconsistent across software, and if your AVIF is animated, only a single frame will convert, since BMP doesn't support animation at all. Upload your file and download a BMP in seconds; it's deleted automatically within an hour.

Why Convert AVIF to BMP
- Legacy Windows software. Some older applications, printer drivers or embedded systems only accept BMP files.
- Technical and scientific tools. Certain CAD, imaging or analysis software still expects uncompressed BMP input.
- Simple, predictable pixel data. BMP's lack of compression makes it useful for some programming, testing or low-level image-processing tasks.
Frequently Asked Questions
Will converting AVIF to BMP change my image quality?
It depends on your original AVIF. If it was encoded losslessly, converting to BMP loses nothing. If it was lossy, BMP preserves whatever quality the AVIF already had, but can't recover anything already lost. The file extension alone won't tell you which type your AVIF is.
Why is the BMP file so much bigger than my AVIF?
AVIF is the most space-efficient format on this site, while BMP typically stores images completely uncompressed. Converting between them usually produces the largest size increase of any conversion here, often dramatically larger.
Will my AVIF's transparency carry over to the BMP?
It depends. Some BMP variants support an alpha channel and some don't, and support varies by the software that opens the file. If your AVIF has transparency, it's worth checking the converted BMP to confirm it came through as expected.
If my AVIF is animated, will the BMP be animated too?
No. BMP doesn't support animation at all, so only a single frame of an animated AVIF will be converted.
When would I actually need a BMP file?
Mainly for compatibility with older Windows software, certain technical or scientific applications, printer drivers or workflows that specifically require an uncompressed bitmap.
Is there a limit on how many AVIF files I can convert?
The free plan allows 10 conversions a day for files up to 10 MB. Paid plans remove the daily limit and raise the file-size cap.
Is it safe to upload my AVIF files?
Yes. Conversion is automated, uploads are encrypted (HTTPS/TLS) and every file is permanently deleted within 60 minutes. Your images are never used to train AI models.
