Tables

Abbreviation File format MIME type File extension(s) Summary
APNG Animated Portable Network Graphics image/apng .apng, .png Good choice for lossless animation sequences (GIF is less performant). AVIF and WebP have better performance but less broad browser support.
Support: Chrome, Edge, Firefox, Opera, Safari.
AVIF AV1 Image File Format image/avif .avif

Good choice for both images and animated images due to high performance and royalty free image format. It offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency, etc. Note that when using AVIF, you should include fallbacks to formats with better browser support (i.e. using the <picture> element).
Support: Chrome, Edge, Firefox, Opera, Safari.

GIF Graphics Interchange Format image/gif .gif Good choice for simple images and animations. Prefer PNG for lossless and indexed still images, and consider WebP, AVIF or APNG for animation sequences.
Support: Chrome, Edge, Firefox, IE, Opera, Safari.
JPEG Joint Photographic Expert Group image image/jpeg .jpg, .jpeg, .jfif, .pjpeg, .pjp

Good choice for lossy compression of still images (currently the most popular). Prefer PNG when more precise reproduction of the image is required, or WebP/AVIF if both better reproduction and higher compression are required.
Support: Chrome, Edge, Firefox, IE, Opera, Safari.

PNG Portable Network Graphics image/png .png

PNG is preferred over JPEG for more precise reproduction of source images, or when transparency is needed. WebP/AVIF provide even better compression and reproduction, but browser support is more limited.
Support: Chrome, Edge, Firefox, IE, Opera, Safari.

SVG Scalable Vector Graphics image/svg+xml .svg Vector image format; ideal for user interface elements, icons, diagrams, etc., that must be drawn accurately at different sizes.
Support: Chrome, Edge, Firefox, IE, Opera, Safari.
WebP Web Picture format image/webp .webp Excellent choice for both images and animated images. WebP offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency etc. AVIF offers slightly better compression, but is not quite as well-supported in browsers and does not support progressive rendering.
Support: Chrome, Edge, Firefox, Opera, Safari

Below we got some ultra high-def large images coming from and . You can expect some page jumps; you should be using the width and height attributes to prevent this.

Placeholder

Notice the image above and below are very large but will always be contained within the viewport and maintain their aspect ratio 😊.

Placeholder
The image above is in a figure (and this is a figcaption). This make the image visually centered otherwise the will be aligned to the reading direction.

Below is an svg image that has an intrinsic width and height (of 512px) so it will grow to that dimension even without the width and height attributes being set.

svg with intrinsic size

However the below svg does not have an a set width and height so it will always grow to the size of the screen and needs a width and height.

svg with no intrinsic size

images are still "inline" elements so if space permits they will be displayed side by side

animated svg small jpg wide png small Animated GIF small webp large avif animated png svg with intrinsic size

However if you place an image inside a text tag such as <p> it will float left or right if it's odd or even respectively. The thought process is that image complements the text but shouldn't break the reader's flow. So if you want an image to be sequential to the text you should use <figure> or place the img after the text tag (as which has been done😉).

if you're wondering why there's so much page jumps is because most of the images don't have their dimensions specified, the way it iis for most images in tthe wild 🥲. Don't do that; this is only for illustrative puposes to show caCSScade's effectiiveness with realistic (though bad) HTML: not only on optimal and best practices code like yours, obviously.
