Thumbnail Mockup Generator
Drop your thumbnail into a realistic feed-style mockup — desktop home grid, mobile feed, or watch-page sidebar — and export as a PNG. Perfect for portfolio cases, sponsor decks, and design reviews.
Thumbnail
How to use this tool
- 01
Upload your thumbnail
PNG or JPG, 1280×720 recommended. The image stays in your browser.
- 02
Set surface and metadata
Pick desktop, mobile, or sidebar. Type the title, channel, views, age, and duration that match the story you're telling.
- 03
Render and download PNG
The mockup is generated locally on a canvas. Save it and drop it into your brief or pitch deck.
Why this matters
A bare 1280×720 thumbnail in a Slack message looks naked — surrounded by other content in a real feed, the same image lands completely differently.
A feed-style mockup gives clients, sponsors, and collaborators the same context viewers have. It's the fastest way to make design feedback land.
Rendering as a downloadable PNG also makes it portable: drop the same image into Notion docs, Figma frames, and case studies without screenshots.
