About AVIF
AVIF is an image format based on the AV1 video codec, published by the Alliance for Open Media in 2019. It supports lossy and lossless compression, transparency, HDR and wide colour.
Modern websites, which use it for images smaller than WebP or JPEG at similar quality.
Encoding AVIF is slow, and older software and operating systems may not open it.
Convert AVIF to BMP online free, no account required — BMP is the Windows bitmap format, usually uncompressed.
Change AVIF to BMP without losing quality — convert AVIF to BMP free in your browser.
Why won't my image editor or older browser open my AVIF file? The format is still young, and support in desktop software lags well behind the major browsers — a conversion to JPG or PNG keeps the image editable.
About BMP
BMP is the device-independent bitmap format of Windows. It usually stores every pixel uncompressed.
Legacy Windows software, simple paint programs and embedded systems.
Without compression a BMP is many times larger than a PNG of the same image.
Why convert an image to BMP? Rarely on purpose: only legacy Windows software and some industrial tools expect uncompressed bitmaps.
What changes when you convert AVIF to BMP
- The AVIF picture is re-encoded as BMP at the default quality settings, so it looks close to the original but is not bit-identical.
- If the AVIF is animated, only its first frame is converted to BMP.

Your converted BMP file is kept for 2 hours, then deleted.
