Image Optimizer v1.0.0

Compress JPEG and PNG uploads, generate WebP copies of every size and serve them locally, with per-image savings in the Media Library.

Start a 14-day free trial → Get the free version

No credit card for the trial. Pro from $4.08/mo, billed annually. 14-day money-back guarantee.

Image Optimizer makes your images smaller on your own server. There is no account to create, no monthly quota and nothing is sent to an outside service: the image library your host already provides (GD or Imagick) does the work.
