How to convert AVIF to WEBM?
You can convert AVIF to WEBM with MConverter in three easy steps:
Choose AVIF files from your device
At the top of this page, drag and drop your AVIFs. You can also click to select AVIF files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste an AVIF file you have copied to clipboard. Converting a folder with AVIF files to WEBM is also supported: simply paste or drag and drop it.
Click or tap on WEBM from the list of target formats
Alternatively, you can use the search field to quickly find the format you need, whether it's WEBM or something else.
Download your WEBM files, after MConverter has finished processing them
There's an option to automatically download the converted WEBM files, so you don't have to press the download icon for each WEBM. On desktop platforms, you can download the WEBM files to a different folder by clicking on SAVE TO... You may see a share icon as well. Use it to directly share the WEBMs with other apps.
About the formats
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 1 minute long. Note that AVIF animations are currently only playable in Chrome and not Firefox.
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.
Common questions about converting AVIF to WEBM
Can I convert AVIF to WEBM in bulk?
Yes, MConverter supports batch converting of multiple AVIFs to WEBMs simultaneously. You can even drag and drop folders containing AVIFs to convert to WEBM. Pasting AVIF files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert an AVIF file to WEBM, if its size is 1 GB?
Yes, with MConverter Premium you can convert big AVIFs, up to 1 gigabyte each. The free version lets you convert files up to 200 MB. If you need to convert AVIF files over 200 megabytes, try MConverter Premium.
Is converting AVIFs to WEBM safe with MConverter?

How long does it take to convert AVIF to WEBM?
For most images, the wait should be less than a minute. If they are animated, it may take a little longer. However, MConverter also supports converting larger images, meaning that it could take a while (up to over an hour, for example).
