About this fake youtube comment generator
The fake YouTube comment generator builds a comment card under a video: the video title, thumbnail and channel name at the top, then the commenter's avatar, name, time label, comment text and like count, with replies listed underneath. Upload your own thumbnail and write the comment that steals the show.
Creators use it for video intros and community-post jokes; teachers use it to discuss online comments. Thumbnails and text stay in your browser, and each export has a small Prank watermark so it isn't mistaken for a real comment. Export at 3x if you plan to zoom in on the comment in a video edit.
How to make a fake YouTube Comment (for fun)
- Pick a prank idea. Start from one of 4 ready-made ideas, or keep the default youtube comment.
- Edit the details. Change names, avatar, messages, times, counts and theme in the Content panel — the preview updates as you type.
- Check the preview. On a phone, switch to the Preview tab; the mockup scales to fit your screen.
- Download or share. Save a PNG or JPG at 2x or 3x, copy it, or share it straight from your phone. Then reveal the joke!

Keep it a joke. Mockly makes parody images for fun. Never use a mockup to deceive, defame, harass or defraud anyone, and don't pose as a real person's or brand's official account. Every export carries a small “Prank · altftool.com” watermark. Not affiliated with YouTube or any app shown.
FAQ

Yes. Add replies beneath the main comment, each with its own name, text, time and likes.

Is it legal to make a fake YouTube screenshot?
Making a parody image for a joke is generally fine. Using one to deceive, defame, harass, impersonate or defraud someone can be illegal and breaks every platform's rules — so don't.
