1. AVIF image format

    A modern image format based on the [AV1 video format](/av1). AVIF generally has better compression than [WebP](/webp), JPEG, PNG and GIF and is designed to supersede them. AVIF competes with [JPEG XL](/jpegxl) which has similar compression quality and is generally seen as more feature-rich than AVIF.

  2. CSS3 Background-image options

    New properties to affect background images, including background-clip, background-origin and background-size

  3. CSS3 Border images

    Method of using images for borders

  4. Crisp edges/pixelated images

    Scales images with an algorithm that preserves edges and contrast, without smoothing colors or introducing blur. This is intended for images such as pixel art. Official values that accomplish this for the `image-rendering` property are `crisp-edges` and `pixelated`.

  5. CSS Cross-Fade Function

    Image function to create a "crossfade" between images. This allows one image to transition (fade) into another based on a percentage value.

  6. CSS3 image-orientation

    CSS property used generally to fix the intended orientation of an image. This can be done using 90 degree increments or based on the image's EXIF data using the "from-image" value.

  7. CSS image-set

    Method of letting the browser pick the most appropriate CSS image from a given set.

  8. HEIF/HEIC image format

    A modern image format based on the [HEVC video format](/hevc). HEIC generally has better compression than [WebP](/webp), JPEG, PNG and GIF. It is hard for browsers to support HEIC because it is [complex and expensive to license](https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding#Patent_licensing). [AVIF](/avif) and [JPEG XL](/jpegxl) provide free licenses and are designed to supersede HEIC.

  9. ImageCapture API

    The Image Capture API provides access to the Video Camera for taking photos while configuring picture-specific settings such as e.g. zoom or auto focus metering area.

  10. naturalWidth & naturalHeight image properties

    Properties defining the intrinsic width and height of the image, rather than the displayed width & height.

  11. JPEG 2000 image format

    JPEG 2000 was built to supersede the original JPEG format by having better compression and more features. [WebP](/webp), [AVIF](/avif) and [JPEG XL](/jpegxl) are all designed to supersede JPEG 2000.

  12. JPEG XL image format

    A modern image format optimized for web environments. JPEG XL generally has better compression than [WebP](/webp), JPEG, PNG and GIF and is designed to supersede them. JPEG XL competes with [AVIF](/avif) which has similar compression quality but fewer features overall.

  13. JPEG XR image format

    JPEG XR was built to supersede the original JPEG format by having better compression and more features. [WebP](/webp), [AVIF](/avif) and [JPEG XL](/jpegxl) are all designed to supersede JPEG XR.

  14. Lazy loading via attribute for images & iframes

    The `loading` attribute on images & iframes gives authors control over when the browser should start loading the resource.

  15. WebP image format

    Image format (based on the VP8 video format) that supports lossy and lossless compression, as well as animation and alpha transparency. WebP generally has better compression than JPEG, PNG and GIF and is designed to supersede them. [AVIF](/avif) and [JPEG XL](/jpegxl) are designed to supersede WebP.
