Pencil2D is a free, open-source desktop application for creating traditional 2D hand-drawn animations using both bitmap and vector graphics. It features a minimal, lightweight design with tools like onion skinning and a timeline, and runs on Windows, macOS, Linux, and FreeBSD.

Use cases

  • make 2d hand-drawn cartoon animations
  • draw frame-by-frame animation with onion skinning
  • sketch and ink animations in raster and vector
  • free alternative to paid 2d animation software
  • create traditional animation on linux mac or windows
  • teach animation basics to beginners

When to choose

  • you want a lightweight, minimal tool focused on traditional frame-by-frame 2D animation
  • you need free, open-source software usable even commercially
  • you want to switch between bitmap and vector workflows in one app
  • you need a cross-platform tool that runs on Windows, macOS, Linux, and FreeBSD

When to avoid

  • you need advanced cut-out/rigged character animation like dedicated 2D rigging tools
  • you require built-in 3D capabilities or compositing/VFX pipelines
  • you need collaborative or cloud-based animation workflows
