How to convert WEBM to AVIF?
You can convert WEBM to AVIF with MConverter in three easy steps:
Choose WEBM files from your device
At the top of this page, drag and drop your WEBMs. You can also click to select WEBM files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste a WEBM file you have copied to clipboard. Converting a folder with WEBM files to AVIF is also supported: simply paste or drag and drop it.
Click or tap on AVIF from the list of target formats
Alternatively, you can use the search field to quickly find the format you need, whether it's AVIF or something else.
Download your AVIF files, after MConverter has finished processing them
There's an option to automatically download the converted AVIF files, so you don't have to press the download icon for each AVIF. On desktop platforms, you can download the AVIF files to a different folder by clicking on SAVE TO... You may see a share icon as well. Use it to directly share the AVIFs with other apps.
About the formats
Video file formats
WebM is a relatively recent video file format for storing high-quality, highly compressed videos with very little quality loss. Because it is also royalty-free, it is frequently used on the web for HTML5 video playback. Its container is based on a Matroska (MKV) profile. It used the VP8 and VP9 technologies for video, and Vorbis and Opus for audio.
Image file formats
AOMedia (Alliance for Open Media)
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.
