Picmal - Image converter & compressor for Mac

Picmal makes converting and compressing images a breeze. Convert or compress batches of images, entirely offline on your Mac—fast and private.

• It's fast and local. Picmal works offline too. You don't need an internet connection for anything. It's all on your laptop.
• It's totally private. I don't upload any of your private data anywhere, whether it's from the analytics tool I use or the way your pictures are handled.
• It's designed to be simple. If I add anything else, it'll be because it's absolutely necessary. There's no pointless AI or random features. It's just a basic UI that works well and looks like an app designed by Apple.
• It's designed to save you time. There are lots of options out there for converting images, but Picmal looks for the best way to make your work easier and save you time.
