Live previewA practical YouTube comment guide
Turn a YouTube comment idea into a ready-to-use image.
Customize the commenter, message, age, reactions, and creator heart, then download a finished card for videos, presentations, or creative mockups.
Set up the commenter
Enter a username of up to 40 characters. The preview adds one @ prefix automatically, whether you include it in the input or not. A username and comment are required to export. Long names are shortened visually with an ellipsis to leave space for the time label.
Upload an avatar in PNG, JPG, WebP, or GIF format, up to 20 MB. The browser resizes it to a maximum edge of 400 pixels and center-crops it into a circle. Animated GIFs become still images. Remove the image to restore the neutral profile silhouette.
Write your comment
Enter up to 1,000 characters. Your preview updates immediately; there is no separate Generate step. The input expands with your text, manual line breaks are preserved, and long lines wrap automatically. Emoji are supported, though their appearance depends on your device.
Set Time ago and choose seconds, minutes, hours, days, weeks, months, or years. The label uses correct singular or plural wording, such as 1 hour ago or 5 hours ago. A value of zero displays just now. These are fixed display labels and do not advance with the real clock.
Light and Dark change the card background, text, and icon colors in both preview and export. The card uses Inter independently of the website interface font. Reset restores the starting example; Undo reset returns to your previous draft during the current visit.
Choose reactions and a creator heart
| Setting | Effect |
|---|---|
| Likes | Sets the displayed count, such as 5K for 5,000 |
| Neutral | Shows both thumb icons as outlines |
| Like | Fills the thumbs-up icon |
| Dislike | Fills the thumbs-down icon |
| Creator heart | Adds a channel avatar with a red heart beside the actions |
| Creator avatar | Replaces the small profile image beside the creator heart |
Only one reaction can be selected. The reaction and like count are independent settings: switching Like or Dislike does not automatically change your count. This comment layout does not show a public dislike count.
Enable Creator heart to reveal the creator-avatar upload control. Without an uploaded image, a neutral avatar appears. Turning the heart off hides it in the artwork while preserving its uploaded avatar in your draft. All engagement values are decorative and do not affect a real YouTube account.
Download or copy
Choose Download image. The desktop export panel places settings on the left and the finished comment on the right. Select a file format and resolution, then download:
| Format | Good for |
|---|---|
| PNG | Lossless text edges and editing workflows |
| JPG | Compact files for slides and sharing |
| WebP | Efficient images for web content |
JPG and WebP use a high quality setting. All formats include the complete comment card on the selected white or dark background. The avatar, username, time, text, likes, selected reaction, creator heart, and Reply label are exported. The workspace, editor controls, and website branding are excluded. There is no watermark.
| Resolution | Width |
|---|---|
| Standard · 2× | 1,200 pixels |
| High · 3× | 1,800 pixels |
| Ultra · 4× | 2,400 pixels |
Height grows with the comment. Exact pixel dimensions appear in the export panel. Very tall comments may exceed browser canvas limits; shorten the text, remove extra line breaks, or select a lower resolution if an error appears. If your browser cannot encode a selected format, the tool reports that limitation so you can choose PNG instead.
Copy image copies a PNG using your selected resolution, regardless of the download format. Image clipboard access requires browser support, a secure connection, and permission. If copying is unavailable, download the image instead. The exported image is a static mockup, not a live comment or video.
For a comment reply bubble, try the TikTok Comment Generator. For another social layout, use the Instagram Comment Generator or Threads Comment Generator.
Drafts and privacy
Auto-save stores your username, comment, both avatars, time label, likes, reaction, creator-heart setting, theme, format, and resolution in this browser. Save draft writes manually. Turning Auto-save off stops automatic writes but does not erase a previously saved draft. If storage is full or unavailable, the editor reports that the draft remains in memory.
Avatars, previews, and exports are processed locally. Drafts do not sync across devices, and generator content is not sent to an application database. Clear this website's browser storage to delete saved drafts. See our privacy policy for details about hosting and analytics.
Common questions
Is the YouTube Comment Generator free?
Yes. Create and download a comment image without an account, payment, or watermark.
Does this publish a comment on YouTube?
No. It generates fictional artwork. It does not connect to YouTube, post comments, or generate real engagement. Fake Generator is independent and is not affiliated with YouTube or Google.
Can I download a transparent background?
This tool exports a complete comment card with a white or dark background. For transparent captions, use the Text Box Generator.
Why is my creator avatar hidden?
The creator avatar is displayed only when Creator heart is enabled. Your commenter avatar remains visible independently.
How should I share a comment mockup?
Use fictional identities or obtain permission for names and photos. Label mockups when viewers might confuse them with real comments, and follow our responsible use policy.
