Why I Built This

Hi, I'm Daniel García (cr0hn). I create content for YouTube, and I got tired of the same annoying workflow:

Open CapCut → Wait for it to load → Import video → Add image → Export → Wait 5 minutes for a simple thumbnail.

I thought: "There has to be a better way to do something this simple."

So I built Thumbnail Maker—a lightweight Mac app that does one thing perfectly: add your custom thumbnail to the first frame of any video. No bloat. No subscriptions. No nonsense.

I made it for myself, but I wanted to share it with the world. If it saves you time, I'm happy. 🙂

Your video now has a custom thumbnail
