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. 🙂
Three clicks. That's it.
Drop your MP4, MOV, or M4V file
Pick your thumbnail (PNG, JPG, HEIC)
Your video now has a custom thumbnail
Everything you need, nothing you don't.
Uses Apple's VideoToolbox for hardware-accelerated encoding. Your Mac's GPU does the heavy lifting.
Smaller than a photo. No external dependencies. No bloat. Just pure Swift code.
Your files never leave your Mac. No cloud. No tracking. No internet required.
Built with SwiftUI. Feels like it came with your Mac. Light and dark mode support.
Automatically speaks your language. English and Spanish supported out of the box.
Works on Intel Macs and Apple Silicon (M1, M2, M3, M4). One download for all.
Download Thumbnail Maker and never open a heavy video editor just for thumbnails again.
