How to Convert AVIF to BMP

AVIF's AV1-based compression is highly efficient, but that efficiency depends on software actually having an AV1 decoder, which many older or minimal programs simply don't include. BMP, by contrast, stores pixel data in a basic uncompressed grid that virtually any image-handling software can read directly with zero codec requirements, which is why some legacy applications or embedded systems specifically expect BMP input.

Converting AVIF to BMP trades away all of AVIF's storage efficiency — BMP files typically end up far larger than the source AVIF — but it guarantees the image opens in software that has no AVIF support whatsoever.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single AVIF file.
3. Drag your AVIF file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to AVIF and the "To" format to BMP.
5. Click Convert. BMP files are written to the output folder, fully offline.
