I was tired of jumping between tools. One website for background removal. Another platform for retouching. The Mac's built-in app for cropping. A different service for upscaling. It was exhausting.

I had old family photos that needed cleaning up. Product shots that needed perfect backgrounds. And I was wasting hours switching between apps just to get one image right.

So I built Klumbo. Everything I need in one place. Remove backgrounds, repair, crop, upscale, erase objects, compose subjects on new backgrounds — all without leaving the app.

No more browser tabs. No more uploads to random websites. No more subscriptions to five different services. Just one tool that does exactly what I need, running locally on my Mac.

Klumbo exists because I needed it. Now you can have it too.
