About Convert to AVIF and Optimise
From the official readme · v1.0.0Description

- Optional metadata stripping and original files retained beside the AVIF copies to keep your workflow flexible.

Frequently asked questions
Will my original files be preserved?
Yes. The plugin leaves your original upload untouched and saves the AVIF version alongside it, updating WordPress to use the optimised copy. If you ever want to revert, simply change the URL or re-select the original image in your content.
Does the plugin update page builders and theme settings?
The bulk optimiser scans post content, excerpts, post meta and the options table so URLs saved by page builders, featured images, theme customiser settings and similar locations will be kept aligned with the new AVIF file.
How does quality work?
Set your preferred quality level between 10 (smallest files) and 100 (highest fidelity). The default value of 82 matches a balanced preset used by many image optimisation tools.
