Spritesheet slicing
Set rows, columns, start/end frames, and playback speed to quickly preview animation frames from a source sheet.
✦ Browser-based sprite animation prep
Clean, preview, and repack sprite animations.
Spritesheet Editor helps game artists and developers turn raw spritesheets or loose frame PNGs into clean animation sheets with masks, pivots, offsets, pixel edits, indexed colors, and flexible import/export workflows including GIF, PSD, MP4, and spritesheet output.
No install. No backend. Open the tool, upload your sprite, edit, and export.
Feature set
Everything needed to prepare a game-ready spritesheet.
Designed around a practical sprite pipeline: import spritesheets, loose frames, GIF, PSD, or MP4 sources, then slice, inspect timing, clean pixels, align frames, reduce colors, and export as GIF or repacked spritesheet.
Animation preview
Scrub the timeline, play the animation, reorder frames, duplicate frames, and import loose frame images.
Mask cleanup
Use mask brush, restore brush, magic wand, background masking, and halo cleanup to remove unwanted pixels.
Pixel editing
Paint directly on frame pixels with a square pixel-perfect brush, dropper, and paint bucket.
Alignment tools
Adjust cage size, pivots, per-frame offsets, scale, rulers, zoom, and pan for precise frame placement.
Indexed color tools
Preview and apply color reduction, preserve transparency, import color tables, and save ACT or PAL palettes.
Pixel Font Creator
Create bitmap fonts, edit letter spacing and offsets, preview text instantly, and export styled text sprites for UI and HUD workflows.
Sprite Compositor
Build timeline-based scenes with layered sprite clips, text, fades, and audio, then render final animations directly from the compositor workspace.
Reference Layer System
Use multiple reference layers with transparency, transforms, and reload controls to keep proportions and animation staging consistent while editing.
Workflow
From raw frames to exported PNG in four steps.
1
Upload
Drop in a spritesheet or import individual frame images, GIF, PSD, and MP4 sources to build your animation timeline.
2
Preview
Set grid dimensions, playback speed, and scrub through frames to check motion and timing.
3
Clean & align
Mask backgrounds, remove halos, edit pixels, set pivot guides, and nudge each frame into position.
4
Export
Export your result as GIF or repacked spritesheet output using the selected cage size and layout.
