SpriteFrame

Browser-based preparation of 2D sprite animation assets. SpriteFrame extracts frames from an MP4 video or packs PNG images into sprite sheets. It supports frame selection and reordering, removal of similar neighboring frames, loop preview, and export of PNG sheets or frame sequences with JSON order and timing. Basic conversion and packing do not require an account. Optional AI image-to-animation and AI background removal use an account and credits. Exported assets still require slicing and playback configuration in the destination engine; the service does not create a ready-made engine project.
