Why Convert WebP to AVIF?
WebP works well for fast-loading images on modern websites, but has a real limitation: some older software and email clients still can't open it. Converting trades that for this: noticeably smaller files than PNG or JPG at comparable quality.
The short version: WebP is optimized for fast-loading images on modern websites, AVIF is optimized for high-efficiency images for fast-loading modern websites, and this converter exists for the moment those two needs don't line up.
Our engine reads a file built around fast-loading images on modern websites and rebuilds it aiming to preserve this: noticeably smaller files than PNG or JPG at comparable quality — rather than producing a generic, lowest-common-denominator result.

AVIF is used by modern browsers (Chrome, Firefox, Edge, Safari). If you were working with modern browsers and web-optimization tools (which produces WebP), this conversion is the direct bridge between the two.

Is there a file size limit for this conversion?

Can I convert the file back from AVIF to WEBP afterward?
Only what AVIF actually carries can come back — anything specific to WebP's role in fast-loading images on modern websites that didn't survive the original conversion won't reappear.
Why would I need AVIF instead of just keeping WEBP?
Mainly when your workflow specifically calls for high-efficiency images for fast-loading modern websites — that's AVIF's whole reason for existing, and WebP isn't built to provide it, since it's focused on fast-loading images on modern websites instead.
