Best way to optimize all my picture

Hello bros

I’m using wordpress but I don’t know how to optimize all my pictures that uploaded (about >1000 pics) and delete all the pictures that optimized.
Thank

(as you know, I need the best quality pictures but the minimun size)

Thank for all your help, hope to receive the helping soon

The above link you can use multiple batch programs that will optimize all of your photos in one shot. Just backup your photos first before you do anything.

Or you can use Visual Studio https://www.visualstudio.com/
using a extension from Web Essentials 2017 - Visual Studio Marketplace

Web Essentials 2017 Mads Kristensen

Either way will BATCH shrink all of your photos in your entire server or directory in various formats.

Both work equally well.
