Codex:

Adds `decoding` attribute to an `img` HTML tag.

The decoding attribute allows developers to indicate whether the browser can decode the image off the main thread (async), on the main thread (sync) or as determined by the browser (auto). By default WordPress adds decoding="async" to images but developers can use the {@see 'wp_img_tag_add_decoding_attr'} filter to modify this to remove the attribute or set it to another accepted value.
