Batch Compress VS Caesium Image Compressor

If you can run the images through a compression site manually, you'll get better results than an automated plugin for sure. Personally, my strategy is to run it through https://batchcompress.com first, then run it through tinypng a few times(tinypng can be run on the same image multiple times.). My images are all under 100 kb and still very high quality. Source: over 2 years ago

If you’re currently creating your Shopify store, keep all of the images in the same place on your PC, and compress them all at once. You can use a tool like batchcompress.com. Source: over 2 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
