Hello PH community!
I’m a YouTube nerd and creator. Like many of you, I spent hours obsessing over thumbnails, only to upload them and realize they looked "meh" next to my competitors.
I built Pro Thumbnail Preview to solve my own workflow struggles. I wanted a way to remove subjectivity and see my "packaging" (thumbnail + title) in the "wild" — on the LIVE YouTube page — before hitting publish.

Why I built this:
Most creators guess if their design works. This tool shows you the truth. It places your idea directly on the YouTube Home and Search pages alongside top-performing videos. If it doesn't "pop" there, it won't get clicks.
What makes it different:
100% Private: Privacy is a priority. All processing happens locally on your computer. Your titles and thumbnails stay yours.
The "Holy Trinity" Check: I’ve integrated specific tests for Blur (recognizability), Composition (Rule of Thirds), and Contrast (visibility).
Mobile Scroll Simulator: Because 70%+ of viewers are on mobile, you need to know if your design holds up on a small screen.
Title Vault: A dedicated space to store and swap title ideas until you find the winner.
The Goal:
Higher CTR → More Views → More Subscribers. Whether you're a beginner or a medium-sized channel, this is about making data-driven design decisions.
I made this public to help the creator community work faster and smarter. I’ll be here all day to answer your questions and hear your feedback!
