How to correctly reduce the size and weight of the image?

Question

PHP

There is a photo 500x334, 56.4 KB to reduce the size, I use this class
$image->resizeImage(368, 200, "crop");
, I get a photo 368x200, 68.7 KB, the goal was to reduce the size, to reduce weight, I'm sure for images with a higher resolution it will be relevant.
This is fine?
Please advise any other solutions. It is possible to use GD and ImageMagick.
I stumbled upon imagine , what is it good for and will it change things?

Answer 1

In the class used, most likely, it is possible to specify the quality (compression ratio, compression, quality) of the picture. And you, for sure, use 100% by default, try reducing it to 85%.
In general, you need to save the image with more compression.
