What the author says it does
Regenerate Thumbnails allows you to regenerate all thumbnail sizes for one or more images that have been uploaded to your Media Library.
This is useful for situations such as:
- A new thumbnail size has been added and you want past uploads to have a thumbnail in that size.
- You’ve changed the dimensions of an existing thumbnail size, for example via Settings â Media.
- You’ve switched to a new WordPress theme that uses featured images of a different size.
It also offers the ability to delete old, unused thumbnails in order to free up server space.
In Memory of Alex Mills
In February 2019 Alex Mills, the author of this plugin, passed away. He leaves behind a number of plugins which will be maintained by Automattic and members of the WordPress community. If this plugin is useful to you please consider donating to the Oregon Health and Science University. You can find more information here.
Alternatives
WP-CLI
If you have command line access to your server, I highly recommend using WP-CLI instead of this plugin as it’s faster (no HTTP requests overhead) and can be run inside of a screen for those with many thumbnails. For details, see the documentation of its media regenerate command.
Jetpack’s Photon Module
The opening of the plugin's own description. The full text, installation notes and changelog are on its WordPress.org page.
Questions the author answers
Is this plugin [GDPR](https://en.wikipedia.org/wiki/General_Data_Protection_Regulation) compliant?
This plugin does not log nor transmit any user data. Infact it doesn’t even do anything on the user-facing part of your website, only in the admin area. This means it should be compliant but I’m not a lawyer.
Latest changelog entry
- Fix: Respect “Skip regenerating existing correctly sized thumbnails” setting.
- Fix: Don’t delete all thumbnails when deleting old unregistered thumbnails size.

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
