Use Spritesheet Generator
Choose this tool when you already have multiple frames and need them packed into one atlas PNG with matching metadata.
Tool
Free spritesheet generator online with PNG and JSON export
Upload animation frames, choose your sheet layout, control fit mode and padding, then export a combined spritesheet plus metadata for downstream engine workflows. This free spritesheet generator online is built for quick browser-based atlas creation without a paid desktop workflow.
Quick Answer
How to make a spritesheet online
To make a spritesheet online, upload your frame images, set the layout options such as columns, cell size, and padding, then build the sheet and export both the PNG atlas and JSON metadata. This tool works best when you already have a sequence of frames ready for animation or atlas-based import.
Generator

Sprite Frames
Upload frames for the spritesheet
images will be arranged in a grid and exported as one PNG
You can also paste an image from the clipboard with Ctrl/Cmd + V
Spritesheet
Preview canvas
Add frames and click build spritesheet to preview the result.
Frames
Frame list
No frames in the spritesheet yet.
Overview
What a free spritesheet generator online should do well
A useful free spritesheet generator online should make it easy to combine frames, control layout settings, and export files you can use in real game workflows. This page focuses on those essentials with a simple browser-based flow for PNG sheets and JSON metadata.
How To
Build a spritesheet in four steps
- Upload the frames you want to combine into one sheet.
- Set the columns, cell size, padding, fit mode, and metadata format.
- Build the spritesheet to preview the frame layout on the canvas.
- Download the PNG atlas and JSON file for your engine or asset workflow.
Tool Choice
When to use Spritesheet Generator vs Pixel Art Converter
Use Pixel Art Converter
Choose the Pixel Art Converter when you still need to turn regular images into pixel-style frame assets first.
Use both in sequence
Convert frames into pixel-style outputs first, then assemble those outputs into a spritesheet when the animation or asset pack is ready.
Next Step
What to do after building a spritesheet
- Import the PNG and JSON into your game engine when the next job is animation playback or atlas-based asset loading.
- Open the 2D Tile Map Editor if the sheet is meant for tile placement or tileset testing.
- Go back to the Pixel Art Converter or Image Resizer if the source frames still need visual cleanup or size standardization.
Use Cases
When to use this spritesheet generator
Animation atlases
Combine character or effect frames into one sheet for engines and tools that expect atlas-style animation input.
JSON export workflows
Export frame metadata when you need row, column, size, and frame positioning data for downstream game imports.
Fast browser iteration
Test columns, padding, fit mode, and background settings quickly before committing to a final spritesheet layout.

FAQ
Spritesheet generator questions
Is this a free spritesheet generator online?
Yes. This page is a free browser-based spritesheet generator for combining uploaded frames into a PNG sheet and exporting JSON metadata.
What can I export from the spritesheet generator?
You can export a spritesheet PNG and a JSON metadata file with frame positions, rows, columns, and layout settings.
Can I control columns, padding, and fit mode?
Yes. The generator lets you control columns, cell size, padding, fit mode, background, and JSON output format.
How do I make a spritesheet online?
Upload frame images, set the layout options, build the spritesheet, then download the PNG atlas and JSON metadata. This is the fastest browser workflow when your animation frames are already prepared.
When should I use the Spritesheet Generator after Pixel Art Converter?
Use it after the Pixel Art Converter when your converted images represent frames or animation states that now need to be packed into one atlas.
What should I do after building a spritesheet?
Import the sheet into a game engine, test it in the 2D Tile Map Editor, or refine the source frames further if the layout or visual style still needs work.
