RenderPop Spritesheet Editor
What it is
RenderPop Spritesheet Editor is a free browser-based workspace for preparing 2D sprite animations. It imports spritesheets, individual frame images, GIF, PSD, and MP4 files, then provides frame-based controls for rows, columns, frame ranges, playback speed, timeline scrubbing, reordering, and duplication. Cleanup tools include masking and restoring brushes, a magic wand, background masking, halo cleanup, pixel brush, dropper, and paint bucket. Alignment controls cover cage size, pivots, per-frame offsets, scale, rulers, zoom, and pan. Color features reduce colors while preserving transparency, import color tables, and save ACT or PAL palettes. Pixel Font Creator makes bitmap fonts and exports styled text sprites. Sprite Compositor builds layered timeline scenes with text, fades, and audio. The editor runs in the browser without a backend, requires no installation or account, and exports GIFs or repacked spritesheets.
