ToonCrafter

ToonCrafter is a browser-based tool that turns static cartoon or illustration keyframes into short animated clips. Users upload two to four keyframe images — each up to 512x512 pixels in WEBP, PNG, or JPG — optionally add a text description of the motion they want, and the tool generates the in-between frames automatically. It exports the result as an MP4, typically around two seconds long at 8 frames per second, in roughly 20 seconds of processing time on the paid tier. Under the hood, the tool uses techniques described as toon rectification learning, a 3D VAE decoder, and sparse sketch guidance to keep the generated motion consistent with the original art style rather than smoothing it into a generic look, preserving fine texture and line detail from the source frames. A free tier allows one animation from two keyframes; paid plans unlock more keyframes, longer clips, faster processing, a priority queue, and portrait-specific tools. ToonCrafter is aimed at hobby artists, illustrators, social media marketers, and content creators who want to animate a static drawing — for stickers, short clips, or presentation graphics — without learning traditional frame-by-frame animation. Because it only interpolates between a small number of user-supplied keyframes, it is suited to short, simple motion rather than full animated scenes or long-form video.
