How do I convert AVIF to BMP?

Upload your AVIF file above. It is converted to BMP automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting AVIF to BMP lose quality?

No new loss is added: BMP stores the picture exactly as it is. Detail that AVIF compression removed earlier can’t be restored.

Will the BMP keep the transparent background?

No. BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).

AVIF compresses still images with the AV1 video codec. It usually produces smaller files than JPG and WebP at the same visual quality and supports HDR and transparency.

Is the AVIF to BMP converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

Why convert AVIF to BMP?

BMP is lossless, so the converted image loses no further detail when you edit and save it again.
BMP is made for older Windows programs, embedded devices and tools that need raw pixels.

What to expect when converting AVIF to BMP

BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).
Converting can’t bring back detail that AVIF compression already removed: the BMP is an exact copy of the image as it is, usually in a bigger file.
