Image Resizer
Shrink every upload before it ever reaches a visitor.
WordPress keeps the 6000-pixel photo somebody dragged in from a phone, and then serves it. Image Resizer caps dimensions on upload, converts to modern formats, and can go back and fix everything already in the library.
The free version is not on WordPress.org yet. Its listing will be at wordpress.org/plugins/subset-image-resizer and goes live with the first release.
What it does
How Image Resizer works
- Caps dimensions on upload
- A max width and height are applied before the original is written to disk, so the oversized file never occupies the uploads directory at all.
- Converts to WebP and AVIF
- Modern formats are generated alongside the original and served by a picture element, with the original kept as the fallback.
- Regenerates the existing library
- The bulk pass runs as a resumable queue that checkpoints after every attachment, so a PHP timeout costs you one image rather than the whole run.
- Leaves the original recoverable
- The untouched upload is retained until you explicitly prune it, because a destructive default on somebody's photo archive is not a default.
Free and Pro
What each version includes
Pro is an add-on plugin that sits alongside the free one. Nothing in the free list moves behind the licence, ever — and if a Pro licence lapses, the free plugin keeps working.

Screens
What it looks like
These are placeholders, not screenshots. Image Resizer is still being built, and a mocked-up admin screen would be a picture of software that does not exist yet. Each frame says what the real image will show.

It is not on WordPress.org yet and there is no date worth printing. Leave an address and you will hear about this one specifically — we record which plugin you asked about, so you are not signed up to news about the other three.
