There was a time, I used to crop and resize tonnes of images for a particular product. I had to make all sorts of images into perfect 1024x1024 squares, while keeping the features/faces in the crop.
It was a time consuming task, so I made this simple website which let people do content-aware bulk cropping and resizing for free. All the existing tools I found online, weren't simple and straight forward enough and very often clouded with Ads.
Recently, I have added feature to get all the social media sizes on a click. I am not sure if its helpful for anyone.
Feedback is welcome and if you need some other simple tool, let me know. I am feeling generous these days, I might make it for you! :D
