Detailed Analysis
When comparing BMP (Bitmap Image File) with AVIF (AV1 Image File Format), it is important to understand the historical and technical context. BMP was established in 1990, while AVIF appeared in 2019.
The main technical difference lies in their compression algorithm. BMP uses lossless compression: it keeps all the original data with no quality loss. AVIF, on the other hand, uses hybrid (both lossy and lossless) compression: you can choose between maximum quality or maximum savings depending on the settings.
