CodeKitHubWhat Is This Tool?
YouTube Shorts Generator recreates the vertical, full-screen mobile look of a real YouTube Short — a full-bleed video area, the stacked like/comment/share action rail on the right, a channel handle and caption overlay near the bottom, and the view count.
It must never be used to fabricate fraudulent evidence, harass or defame someone, or impersonate a real channel's actual Shorts — doing so may be illegal depending on your jurisdiction.
Everything is generated locally in your browser using the HTML Canvas API; nothing is ever uploaded to a server.
Why Use It?
- 100% local rendering — your content never touches a server.
- A/B test a caption or thumbnail idea before publishing a real Short.
- Mock up a Short for a pitch deck, tutorial slide or design portfolio piece.
- No account, no upload, no watermark — just fill in the fields and download.
How to Use
- Set the channel name, handle style and subscriber count.
- Pick a background gradient or upload your own video-frame image.
- Type the caption text that overlays the bottom of the video.
- Set the view, like and comment counts, then click "Download PNG" to save the image.

Responsible use
This generator exists to make it easy to create clearly fictional mockup images for humor, storytelling and design work. If you share an image made with this tool, consider adding context so viewers understand it is not a real Short.
Frequently Asked Questions
Is it legal or ethical to use this tool?
The tool itself is legal to use for entertainment, mockups, presentations and design work. What is not legal or ethical is using the generated image to deceive someone. Please only use this for clearly fictional or illustrative purposes.
Does the tool upload my content anywhere?
No. Everything you type or upload stays in your browser's memory and is drawn directly onto a canvas element with JavaScript. The PNG is generated and downloaded on your device — nothing is ever sent to a server.
How is this different from a full YouTube video mockup?
This tool matches the native vertical, full-screen mobile Shorts interface — including the side action rail and overlay caption — rather than the horizontal video-player layout used for regular YouTube videos.
What image size does it export?
The exported PNG is 360×640, matching the vertical 9:16 aspect ratio used by real YouTube Shorts.
Should I use this or one of the other YouTube mockup generators?
If you're mocking up the vertical, full-screen Shorts player with its side action rail, use this Shorts generator. If you need a comment thread under a video instead, use the YouTube Comment Generator; if you need a full channel page with banner and video grid, use the YouTube Channel Generator.
