LibreSprite vs RenderPop Spritesheet Editor

LibreSprite is a free, open-source program for creating and animating sprites. It provides real-time animation previews and onion skinning, with sprites arranged in layers and frames. Users can edit multiple sprites at once, draw in tiled mode, and use pixel-precise tools such as filled contour, polygon, and shading mode. The program includes ready-to-use palettes and supports creating custom ones. Listed export formats include PNG, GIF, JPEG, BMP, PCX, TGA, ICO, FLI/FLC, WebP, and ASE; sprite-sheet export is also listed. Scripting methods cover loading palettes, cropping and resizing sprites, and saving them. LibreSprite is available for Windows, macOS, Linux, and Android. The project developed independently after originating as a fork of an Aseprite commit covered by GPL version 2. Version 1.0 is listed as supported, and the project security page reports no published advisories. The plan is free.

RenderPop Spritesheet Editor is a free browser-based editor for preparing and exporting 2D sprite animations. It accepts spritesheets, individual frames, GIF, PSD, and MP4 sources. Frame-based controls let users set rows and columns, choose ranges and playback speed, scrub a timeline, reorder frames, and duplicate them. Cleanup tools include masking and restore brushes, a magic wand, background masking, halo cleanup, pixel brush, dropper, and paint bucket. Alignment covers cage size, pivots, per-frame offsets, scale, rulers, zoom, and pan. Color tools reduce colors while preserving transparency, import color tables, and save ACT or PAL palettes. Pixel Font Creator handles bitmap fonts, spacing, offsets, previews, and styled text sprites. Sprite Compositor builds scenes with layered clips, text, fades, and audio, then renders animations. Reference layers support transparency and transforms. Exports include GIFs, repacked spritesheets, styled text sprites, and palettes. The maker says it runs without a backend and requires no installation or account.
