Define grid layout
Set rows, columns, and cell dimensions so each frame maps to a predictable position.
Add padding and spacing
Insert pixels between frames to prevent bleeding in game engines or GPU filtering.
Preview the atlas
Verify frame order matches your animation sequence or CSS coordinate map.
Download sprite sheet
Export one PNG image containing all frames for your engine or stylesheet.

Why use this tool

2D game animation frames in one texture atlas
CSS image sprites for legacy web icon sets
Emoji or sticker packs for chat app prototypes
UI icon bundles for mobile app design handoff

Frequently asked questions

Are my files uploaded to a server?: No. All image processing runs entirely in your browser on your device. Your files are never uploaded, stored, or transmitted to any server.
What is a sprite sheet used for?: A sprite sheet combines many small images into one file. Games and websites load it once, then display regions as individual sprites or animation frames.
Do all frames need the same size?: Uniform cell sizes simplify animation math. Mixed sizes work if you track variable coordinates in your game code or CSS.
PNG or WebP for sprite sheets?: PNG is standard for transparency and broad tool support. WebP can be smaller but verify compatibility with your engine.
Why add padding between sprites?: Padding prevents color bleed from neighboring frames when GPUs sample textures with linear filtering.
Can I generate a JSON map file for the sprites?: This tool exports the combined image. Note cell coordinates manually or use engine-specific tools for metadata export.
How do I use a sprite sheet in CSS?: Set background-image to the sheet and shift background-position to show each icon cell by its x/y offset.
