The Fonwork online image processer is a game-changer! I tested it on a few product photos just to try it out, Wow, the files ended up smaller than Photoshop's compression, with barely any quality loss.

I've been using this Fonwork's image online tools forever — it's my go-to since my school's ancient computers can't run Photoshop. No installs, no fuss, and super easy for beginners. 10/10 would recommend to anyone!
