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 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.
Common questions about converting to AVIF
How to free up space when I have lots of photos I don't want to delete?
Use MConverter to convert your images to AVIF. It's a newer format which uses more efficient compression. This way, your photos will take up less space, while their quality remains essentially identical as before. After you have downloaded your converted photos, you can delete the original image files from your phone or computer, and enjoy the extra free space. Later, when you wish to view your old photos, you may convert them to PNG without losing quality, or to JPG.
Can I convert to AVIF in bulk?
Yes, MConverter supports batch converting to AVIF. You can even drag and drop folders to convert to AVIF. Pasting files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert a file to AVIF, if its size is 1 GB?
Yes, with MConverter Premium you can convert big files, up to 1 gigabyte each. The free version lets you convert files up to 100 MB. If you need to convert files over 100 megabytes to AVIF, try MConverter Premium.
Is converting to AVIF safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your files are only accessible by you. 4 hours after the conversion completes, they are automatically deleted from MConverter’s servers. You can also delete your files immediately after finishing the conversion by clicking the bin icon. Join others who have trusted us to convert over 4,475,668 files so far.
How long does it take to convert a file 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).
