High Dynamic Range (HDR): support for storing images that can represent bigger contrasts between the lightest and darkest parts of the image.Animation/multi-image storage (similar to animated GIFs, but with much better compression).30% compression for the same JPG set (source: AVIF WebP Comparison (CTRL Blog)). Generally, AVIF has better compression than WebP - median 50% vs.lossy AVIF images are around 50% smaller than JPEG images). Excellent lossy compression compared to JPG and PNG for visually similar compression levels (e.g.
However it also has disadvantages for some cases, as video and image encoding have some different requirements. The format benefits from the significant advances in video encoding in recent years, and may potentially benefit from the associated support for hardware rendering.
It offers state-of-the-art features and performance, without the encumbrance of complicated licensing and patent royalties that have hampered comparable alternatives.ĪV1 is a coding format that was originally designed for video transmission over the Internet. Note: AVIF has potential to become the "next big thing" for sharing images in web content.

WebP offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency etc.ĪVIF offers slightly better compression, but is not quite as well-supported in browsers and does not support progressive rendering. Vector image format ideal for user interface elements, icons, diagrams, etc., that must be drawn accurately at different sizes.Įxcellent choice for both images and animated images.

Note that when using AVIF, you should include fallbacks to formats with better browser support (i.e. It offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency, etc.

Good choice for both images and animated images due to high performance and royalty free image format. Supported: Chrome, Edge, Firefox, Opera, Safari. Good choice for lossless animation sequences (GIF is less performant).ĪVIF and WebP have better performance but less broad browser support. The image file formats that are most commonly used on the web are listed below.
