Excellent plugin

Image compression is excellent.
Easy to use & affordable.
AI SEO for image fields is brilliant!!! Saved me many hours.
No need for support (so far)… and that’s how you want it… ie. works out of the box and does what it says on the lid. 🙂

I love the ShortPixel interface. So smooth and easy to navigate. The compression features are great and it is economical to use as well.
Been Using ShortPixel for Years. Fantastic Service.

I have been using ShortPixel on all my WordPress websites for years. I really like the image quality they produce for compressed images. Saves so much on file size and yet compromises so little on quality, if any. (you can control the quality)
It is a feature rich plugin. Easy to navigate and understand the settings and options, yet powerful in what you have control over. Recently they have added AI Image SEO alt text generation. It works great saving hours of my time manually generating descriptive alts.
Support team at ShortPixel are great. Just an all round super plugin and service. I highly recommend them.
