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.

The colors in the palette all use an 8-bit depth.Įach pixel is represented by two D-bit values: the intensity of the greyscale pixel and an alpha sample, indicating how opaque the pixel is.Įach pixel is comprised of four D-pixel color components: red, green, blue, and the alpha sample indicating how opaque the pixel is.Ĭreative Commons Attribution-ShareAlike license They're also commonly used for the animated portions of web browsers' user interfaces.Ĭhrome 59, Edge 12, Firefox 3, Opera 46, Safari 8Įach pixel consists of a single D-bit value indicating the brightness of the greyscale pixel.Įach pixel is represented by three D-bit values indicating the level of the red, green, and blue color components.Įach pixel is a D-bit value indicating an index into aĬolor palette which is contained within a PLTE chunk in the APNG file Support: Chrome, Edge, Firefox, Opera, SafariĪPNG is a file format first introduced by Mozilla which extends the PNG standard to add support for animated images.Ĭonceptually similar to the animated GIF format which has been in use for decades, APNG is more capable in that it supports a variety of color depths, whereas animated GIF supports only 8-bit indexed color.ĪPNG is ideal for basic animations that do not need to synchronize to other activities or to a sound track, such as progress indicators, activity throbbers, and other animated sequences.įor example, APNG is one of the formats supported when creating animated stickers for Apple's iMessage application (and the Messages application on iOS). 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. WebP/AVIF provide even better compression and reproduction, but browser support is more limited.

Lossless and indexed still images, and consider WebP, AVIF or APNG for animation sequences. Good choice for simple images and animations. Supported: Chrome, Edge, Firefox (still images only: animated images not implemented), Opera, Safari. 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.
