Use the original and a downloaded sample to judge the tradeoff. There is no fixed compression saving that applies to every image.
WebP can be useful for web delivery and supports transparency. The WebP format can store animation, but this tool exports one still frame from animated inputs; animation is not preserved. This tool passes a quality value to the browser encoder. A quality setting of 100 does not guarantee lossless WebP output; download and inspect the result.
AVIF can offer efficient compression, depending on the source and encoder. Reading AVIF and writing AVIF are separate browser capabilities. An unavailable output format cannot be exported by this tool.
Try both on a representative image when your workflow supports them. Check decode support for the audience and encode support in this browser separately. Preserve a compatible alternative where necessary.
Inputs must be readable by your browser. PNG, JPEG and WebP are common output choices; AVIF encoding depends on the browser. GIF, BMP and ICO output are not provided by the native encoder used here. Exports over 16,384 pixels per side or 80 million pixels are rejected; device memory can impose lower practical limits. There is no daily conversion quota.
Compare JPEG, PNG, WebP and AVIF by content type, transparency, compatibility and editing needs.

Practical guides for local conversion, image delivery, accessibility and choosing formats for a website.
Compare a WebP export with the PNG original before choosing the delivery format.
Image optimization supports accessibility and loading performance. Ranking gains cannot be promised.
A WordPress library can use several formats. Keep editing originals and choose delivery files for each use.
