PNGTuber Plus is a free desktop app for customizing 2D PNG VTuber avatars, with tools aimed at remaining approachable for beginners. Users can add PNG images or sprite sheets for animated sprites. Sprites can move with sine waves, attach to other sprites, trail behind movement, or bounce and jiggle. Individual sprites can appear or disappear when speaking or blinking, and lip sync is supported. Users can change the background color for transparency or green-screen use in OBS, then save and share avatars. Builds are available for Windows, macOS, and Linux. The developer accepts optional support payments, but the software itself is free. The maker links to a public GitHub repository containing the source code and asks users to report bugs, issues, or suggestions through the itch.io community page. Steam lists Windows 10 minimum requirements of a 64-bit processor and operating system, 4 GB RAM, 2 GB graphics, and 100 MB storage.
