BMP

BitMap

BMP is a standard image file format primarily used in Microsoft Windows. Its main characteristic is that it typically stores pixel data uncompressed, resulting in very large file sizes but offering perfect image quality. Although it supports some basic compression, BMP lacks the efficiency and features (like transparency) of modern formats, making its use mostly limited to simple, high-fidelity internal application images.

AVIF

AV1 Image File Format

AVIF is an open image format based on the AV1 video codec. It offers superior compression (30-50% smaller than JPEG) with better quality, supporting HDR and transparency. Its adoption is growing rapidly, with support now available in major web browsers like Chrome, Firefox, and Opera, positioning it as a key next-generation web image standard.
