Description

The AV1 Image File Format (AVIF) is a new format which promises better compression and smaller file sizes than JPEG, PNG, WebP, and all other current image formats on the web. Based on the generic HEIF image format, AVIF supports alpha transparency, HDR, lossy and lossless compression. AVIF is already being used by Netflix and Microsoft.

Support in Google Chrome and Chromium-based browsers (like Microsoft Edge and Opera) has landed in late August 2020. Firefox can display AVIF images from version 93, released in October 2021. Meanwhile, Apple's Safari will support AVIF in iOS 16 (coming Fall 2022).

MConverter's AVIF encoder uses a Constant Rate Factor (CRF) of 10, so that there is no noticeable reduction in image quality while keeping the file size as small as possible.

MConverter also lets you create AVIF animations from video or GIF, up to 5 minutes long. Note that AVIF animations are currently only playable in Chrome and not Firefox.
