What is AVIF?
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 still does not support AVIF.
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.
Common questions about AVIF conversions
How to open an AVIF file?
If you don't know how to view an AVIF file, you can convert it to another format you already recognize. You can use MConverter for the conversion.
Can I convert AVIF files in bulk?
Yes, MConverter supports batch converting of multiple AVIF files at once. You can even drag and drop folders containing AVIFs. Pasting AVIF files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert an AVIF file, 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 safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your AVIF files are only accessible by you. 24 hours after the conversion completes, they are automatically deleted from MConverter’s servers. You can also delete your AVIFs and other converted files immediately after finishing the conversion by clicking the bin icon. Join others who have trusted us to convert over 2,821,016 files so far.
How long does it take to convert AVIF?
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).
