Convert AVIF to BMP
BMP keeps exactly what the AVIF holds, without adding quality. Transparent areas get a solid background.
They open in the converter with BMP selected.

What changes
BMP is lossless, so nothing else is lost. What it can’t do is bring back the detail AVIF already discarded.
The file gets larger: BMP needs more space for the same content.
Watch out for transparency: AVIF has an alpha channel and BMP doesn’t, so transparent areas are filled with the background color (white unless you pick another).
Your browser may not be able to open AVIF files, but the converter reads the file itself, so it can still convert it.
When it’s worth it
Choose BMP for: Legacy Windows graphics and raw pixel work. Any program can read it, with no compression to decode.
Stay with AVIF for: Websites where small image size matters.

Questions
Does converting AVIF to BMP lose quality?
Nothing more is lost, but the detail AVIF already discarded doesn’t come back.
What is the BMP format?
Microsoft's uncompressed bitmap from 1992: a small header followed by raw pixel rows, usually 24 bits per pixel. Windows still uses it internally, for instance for images copied to the clipboard.
What is the AVIF format?
The AV1 still image format standardized as ISO/IEC 23000-22: images inside the same box container as HEIF, but compressed with AV1. It reaches HEIC-like sizes with a far more complete toolchain, and it supports HDR and alpha.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
