About PNG

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a free replacement for GIF. It supports full colour and an alpha channel for transparency.

Screenshots, logos, icons, diagrams and any image with text or sharp edges.

For photos a PNG is several times larger than a JPEG, and plain PNG has no animation (that is APNG).

Convert PNG to AVIF online free, no account required — AVIF is a modern image format based on the AV1 video codec.

Why is my PNG so much bigger than the same photo as JPG? PNG stores every pixel losslessly, which is ideal for screenshots and graphics but wasteful for photos — JPG or WebP compress photographs far more efficiently.

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.

Why convert images to AVIF? It is the smallest format today’s browsers accept, often half the size of JPG, with HDR and wide-colour support on top.
