   TinyFast▲319

   I am a developer. I have been building stuff for the last 13 years. One common challenge in all my projects is compressing assets to make them as small as possible. I used to end up using online compressors, but this has a lot of privacy concerns. So, I finally set down for couple of weeks and built this simple app. I can just drag and drop assets in it and it shrinks them. It currently supports around 25 file types. I built a lot of iOS apps but this is the first time building a macOS app, so any feedback is welcome.
