Convert image files with our easy to use and free tool. Our tool lets you upload a HEIC (High Efficiency Image File Format) file and from this, create a new image saved in the AVIF (AV1 Image File Format) format that you can then download and edit/use within image file editors or use for high definition printing applications.
Here are 2 simple steps to convert your HEIC to AVIF.
First click the "Upload..." button, select your HEIC file to upload. Select any configuration options. When the HEIC to AVIF conversion has completed, you can download your AVIF file straight away.
We aim to process all HEIC to AVIF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the HEIC file you submit to us. The resulting AVIF file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our HEIC to AVIF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our HEIC conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
The HEIC is a modern image format with the final specification completed in 2015. The format is a container format which whilst mostly used for storing image data the format can actually support video, audio and text data streams.
HEIC files are binary in nature and offer an alternative to existing digital photo formats such as JPEG featuring better compression whilst retaining comparable image quality. In some cases the file size can be 50% that of the equivalent JPG file.

The AVIF format is an image based container format designed to store image or image sequences which are compressed with the AV1 compression algorithm. The format has been around since 2019 and is based on the HEIF container format and as such it competes with the HEIC image format.
During tests the format has shown to perform better than JPG files not just in the reduced file size but in overall image quality. Support for the format is growing and is already supported in the Chrome and Firefox web browsers. AVIF files can also be opened in many 2D image editing applications.
