I use dynamically created thumbnails, but switching from WP basic pictures management to this left some error in media metadata that I was wondering how to fix (appart from directly modifying the database...).
This plugin just did the job for me.
It already inspires me an other plugin I could write: WP do not reorder the sizes in SRCSET but uses the order in metadata, leading to display problem on some browsers (Chrome for instance) as they get a bigger size than expected.
Maybe that could be something to correct like you did in your plugin.
Thank you very much!

I migrated all the media from an old wordpress site to a new one and forgot to migrate the postmeta table and lost all the media IDs, I was racking my brain with SQL when I found this plugin that solved my problem with a few clicks.
Thank you very much and congratulations to the developer!
Best regards,
Pedro Nascimento
