AppRanks verdict
Generated from live marketplace data — refreshed daily
Regenerate Thumbnails is a highly rated WordPress app with a growing review traction. It is listed in the Popular category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 395 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
Pros
- +High average rating (4.6★) signals consistent merchant satisfaction
- +Published by Alex Mills — established developer track record
Cons

How Regenerate Thumbnails works
Show full descriptionShow less
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.

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
Jetpack is a plugin by Automattic, makers of WordPress.com. It gives your self-hosted WordPress site some of the functionality that is available to WordPress.com-hosted sites.
The Photon module makes the images on your site be served from WordPress.com’s global content delivery network (CDN) which should speed up the loading of images. Importantly though it can create thumbnails on the fly which means you’ll never need to use this plugin.
I personally use Photon on my own website.
Disclaimer: I work for Automattic but I would recommend Photon even if I didn’t.
