PNGTuber MakerFour states, one canvas, test it with your mic.

A PNGTuber is just images that swap: one with the mouth closed, one with it open, and the same two with the eyes shut so you can blink. The trick is that they must line up perfectly, or your head jumps every time you talk. Drawing them separately almost guarantees a jump.

So we draw all four states in one 2×2 sheet with an instruction that only the mouth and eyes change, then slice them with the same alignment math used for animated emotes. They land on the same 1024×1024 canvas in the same spot.

Press “Start talk test” and talk. Your mic level opens the mouth; a random blink fires every few seconds; a little bounce sells the motion. Adjust the threshold slider until normal speech opens the mouth and keyboard clicks don’t. Switch the background to green screen to see it like OBS will.

The test runs only in your tab with the Web Audio API. Nothing is recorded or uploaded. There’s also a free standalone PNGTuber tester for images you already have.

1. 1
   veadotube mini

   Drag idle.png, talking.png, blink-idle.png and blink-talking.png onto the matching states, set the mic threshold, add the window capture in OBS.

2. 2
   PNGTuber Plus

   Create a sprite, set the idle and talking images, enable blinking and add the blink images.

3. 3
   OBS only

   Add idle.png as an Image source for a still avatar; use an app or a plugin for mouth movement.

Mood sets (happy, angry, sad, surprised) export into their own folders with the same four file names, so apps with hotkeys can switch expressions.

• Set the mic threshold just above your room noise, so the mouth stays shut when you’re typing.
• Blink every 2–6 seconds; the talk test does this randomly, and most apps can too.
• A small bounce while talking (most apps have a “bounce” option) does more than extra frames.
• Use a mood set on a hotkey for big moments: surprised for jump scares, angry for losing streaks.
• Keep the avatar in the same corner every stream; viewers learn where to look.

The PNGs use the full 1024×1024 canvas with transparent padding, so you can scale them down in OBS without blurry edges.

Upload a picture of yourself or your existing avatar under “I have a picture”, or design a character from five questions. Either way, the four states are drawn from your locked sheet, so your PNGTuber matches your emotes and badges.

A PNGTuber setup costs nothing but images and a free app, runs on any PC, and doesn’t need face tracking. Viewers still get a face that reacts when you talk, which keeps a stream feeling personal. Many streamers stay PNGTubers for years; others use it as a bridge to a Live2D model. Either way, the four states here match your emotes and badges, so the whole channel looks like one character.

It isn’t a rigged model and it doesn’t track your face. If the mouth change also nudges the head in one of the four cells, redo the set (1 credit). Animated GIF states aren’t made here yet; the PNGs are what every app accepts.
