## FAQ

**What size is a YouTube thumbnail for Roblox videos?**
1280x720 pixels (16:9) is YouTube's standard. Export at 1920x1080 if you want extra resolution for editing — YouTube accepts both.

**Can I use my Roblox avatar in a YouTube thumbnail?**
Yes. Renderbux loads your real rig by username and exports a high-resolution PNG you can drop into Canva, Photopea or Figma with text and effects.

**How is this different from AI YouTube thumbnail generators?**
AI tools invent a character from a prompt. Renderbux loads your Roblox username and exports your real rig at 1280x720 or 1920x1080. Viewers see the same avatar they know from your channel, not an AI stand-in.

**Do I need Blender for Roblox YouTube thumbnails?**
No. The browser studio handles posing, lighting and export. Add text and overlays in any image editor after export.
