Maximize your potential on YouTube byraising your CTR

Thumbnails I design to stop the scroll. You keep the content, I craft the first frame that drives more clicks.

About

Who I am?

I’m Corentin. I’ve been a YouTube thumbnail designer for 5 years, helping creators turn the first frame into a real click lever.

I’ve worked with influential channels and delivered thousands of thumbnails built to stop the scroll, not just decorate the feed.

My approach stays simple: a clear angle, a clean render, and a direct exchange so you can publish fast with an image that feels like you.

Thumbnails that earn clicks, not just decoration.

I design them to stop the scroll, lift your CTR, and fill your channel with views.

Talk about your project

Give me the context, your photos, and I’ll make a banger.

What’s my working method?

A short, clear process built around the click and your channel style.

Brief and exchange

You send photos, the video link, and the message to land. We talk it through so the angle is locked before I start.

Design and layout

I build your thumbnail in Photoshop with a sharp face, readable text, and strong contrast. Every detail is made to stop the scroll and drive the click.

Delivery and tweaks

You get an upload ready file within 24h. Tweaks are included until you’re happy, then you publish on YouTube.

Pick the format that fits

One thumbnail to test, a pack to ship faster, or custom ongoing support.

They say it better than I do

Four client video reviews, straight from their channels.
