Made this tutorial video on how to us this tool that I built for myself, Matted.

Matted is a photo formatting tool built for photographers. Drop in your photos, choose your output ratio (4:5 portrait, 1:1 square, or 9:16 story), set your background color, adjust your padding - and export the whole set as a ZIP in seconds.

Everything runs on your device. No uploads. No account. No subscription required to get started.

Try it for free, buy it with bitcoin if you like it. Appreciate the support and user feedback!
