EWWW Image VS Caesium Image Compressor

For pictures I recommend using a mix of WordPress image sizes and the ewww image plugin. How this works is you set the sizes for the images in WordPress that you want it to display for desktop, tablet and phone and the ewww plugin takes all the pictures and makes version of each size and delivers the right size picture for the device for you without you having to think about it. You can add your own sizes. This... Source: about 1 year ago

I also use EWWW for optimizing my images on Wordpress and converting images to WEBP. - Source: dev.to / almost 3 years ago

I also use Caesium Image Compressor on my ROMs and Themes folder to reduce their size and improve the RG35XX's responsiveness. Source: 12 months ago

If you want further compression you could check out Caesium Image Compressor which is free (and I'm not affiliated with it incidentally, I just like it). Source: about 1 year ago

Caesium Image Compressor can do the job and it is easy to use. There is also imagemagick which is basically the swiss-knife for image editing, but based on you having looked for websites first, I assume you don't look for a commandline tool (imagemagick is a commandline tool).

I can recommend Caesium , a utility (Windows, MAC version in Alpha test) to remove all EXIF, metadata etc which will reduce your JPG in size quite a lot without using higher JPG-compression (lower quality). Source: almost 3 years ago
