What Is a PNGtuber? Complete Beginner's Guide

If you've watched a stream where the creator's on-screen avatar is a single flat image that just bobs slightly and swaps its mouth open and closed while they talk, you've watched a PNGtuber. It's become one of the most popular ways for streamers to add a visual identity without the cost and complexity of a full VTuber setup.

PNGtuber vs. VTuber: what's the difference?

A VTuber uses a fully rigged avatar — either a 3D model or a Live2D rig — that tracks your face and body movement in real time through a webcam, translating your expressions and head tilts onto the character. It looks impressive, but building or commissioning a properly rigged model is expensive and technically involved.

A PNGtuber strips this down to the essentials: a small set of static PNG images (usually just "mouth closed" and "mouth open," sometimes with a couple of extra expressions like surprised or angry) that swap automatically based on your microphone input. There's no face tracking, no rigging, no 3D model — just artwork and a lightweight piece of software watching your mic level.

Why creators choose PNGtubing

• Cost — a rigged VTuber model can run from a few hundred to several thousand dollars commissioned from an artist. A PNGtuber avatar needs only 2-4 static images.
• Simplicity — no camera, no face tracking calibration, no rigging software to learn.
• Privacy — you never need to be on camera at all, which is a big draw for creators who want a visual presence without showing their face or space.
• Flexibility — swapping to a new look is as simple as swapping the image file, with no re-rigging required.

What you need to get started

1. Avatar images — at minimum a "mouth closed" and "mouth open" PNG of your character, ideally with a transparent background so it layers cleanly over your stream scene.
2. PNGtuber software — free tools like PNGTuber Plus or VTube Studio's simple-avatar mode read your microphone input and switch between your image states automatically.
3. OBS or Streamlabs — add the PNGtuber software's output window as a Window Capture or Game Capture source in your streaming software.

Where to get PNGtuber avatar images

You can commission custom artwork from an illustrator, draw your own, or start with free assets while you figure out your look. SketchValley's PNGtuber category has ready-to-use transparent PNG images you can download instantly — no signup, no watermark — to get a stream up and running today, or to use as reference while commissioning something custom later.

Tips for a good PNGtuber setup

• Use a transparent background PNG so your avatar sits cleanly over your game capture or webcam without a visible box behind it.
• Keep your "mouth open" and "mouth closed" states at the same canvas size and position so the swap doesn't cause the avatar to jump or shift.
• A subtle idle animation (a slow bob or breathing effect) in your PNGtuber software makes a static image feel much more alive, even without face tracking.
• Start simple — you can always add more expression states later once you know which moments in your stream actually call for them.
