What is AVIF?
AV1 Image File Format (AVIF) — A next-generation format based on the AV1 video codec. Delivers superior compression — up to 50% smaller than JPEG — with support for HDR, wide color gamut, and transparency.
- Format type: Lossy / Lossless
- File extension: .avif
What is BMP?
Bitmap Image File (BMP) — An uncompressed raster format native to Windows. Preserves pixel-perfect quality with zero compression artifacts, resulting in large file sizes.
- Format type: Uncompressed
- File extension: .bmp
Why Convert AVIF to BMP?
Both AVIF and BMP are lossless formats, so converting between them preserves full image quality. This conversion is useful for compatibility — BMP may be better supported by your software, platform, or workflow.
