How to convert HEIC to AVIF?
You can convert HEIC to AVIF with MConverter in three easy steps:
Choose HEIC files from your device
At the top of this page, drag and drop your HEICs. You can also click to select HEIC files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste a HEIC file you have copied to clipboard. Converting a folder with HEIC 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. You may see a share icon as well. Use it to directly share the AVIFs with other apps.
About the formats
Image/Picture file formats
MPEG (Moving Picture Experts Group)
HEIC is a new graphics format, containing one or more images stored in the High Efficiency Image Format (HEIF). This format, which is more efficient than JPEG, is heavily pushed by Apple on iOS and MacOS.
However, other operating systems may not be able to open such files, so it is a good idea to convert to another image format with wider adoption (JPG, PNG, or more efficient ones like WebP, JXL, or AVIF) when sending a photo from an iPhone, for example.

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 converting HEIC to AVIF
Can I convert HEIC to AVIF in bulk?
Yes, MConverter supports batch converting of multiple HEICs to AVIFs simultaneously. You can even drag and drop folders containing HEICs to convert to AVIF. Pasting HEIC files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert a HEIC file to AVIF, if its size is 1 GB?
Yes, with MConverter Premium you can convert big HEICs, up to 1 gigabyte each. The free version lets you convert files up to 200 MB. If you need to convert HEIC files over 200 megabytes, try MConverter Premium.
Is converting HEICs to AVIF safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your HEIC 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 HEICs and other converted files immediately after finishing the conversion by clicking the bin icon. Join others who have trusted us to convert over 2,639,373 files so far.
How long does it take to convert HEIC to 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).
