VF Image Resizer+

I like and recommend this app, however it lacks some features, like: - integration into Content > Files in the admin panel - conversion to webp format - custom meta tag formatting, just to name a few. And, of course, I used it for the 200 conversion tasks which are free.

Just make a test and it looks fine!

quickly resized my images and Instantly raised my speed score, very nice app, but only limits to 200 a month for free plan

Image Bulk Resize is easy to use and compresses images without losing fidelity. I would give 5 stars except it lacks a function to compress all images. It is limited to Product, Collection, and Featured Images in Blogs. I use other images throughout my site that it doesn't recognize.
