Sprite Sheet Maker
Combine individual frames into one sprite sheet, ready for any game engine. Drop your PNGs, tweak columns and padding, and export the sheet with a matching JSON atlas — free, right in your browser.
Drop your frame images here, paste them, or
Your images never leave your browser — everything runs locally.
How it works
- Drop your frame images onto the tool — they are sorted by file name, so name them frame-01, frame-02 and so on.
- Choose the number of columns or leave it on auto for a near-square sheet.
- Add padding between frames if your engine needs breathing room to avoid texture bleeding.
- Export the sheet as a PNG and download the JSON atlas with every frame's position and size.
- Load the sheet and atlas in Phaser, PixiJS, Godot, Unity or any engine that reads TexturePacker-style JSON.
Frequently asked questions
How do I make a sprite sheet from PNG images?
Drop or paste your PNG frames onto the tool. They are packed into a grid in file-name order, and you can adjust columns and padding before exporting the finished sheet as a PNG — no software to install, no upload.
What is the JSON atlas for?
The atlas maps every frame's name to its exact position and size on the sheet. Engines like Phaser, PixiJS and Godot read it directly, so you don't have to type coordinates by hand.
What order are my frames packed in?
Frames are sorted by file name using natural order, so frame-2 comes before frame-10. Name your files with numbers in sequence to control the animation order.
Can I mix images of different sizes?
Yes. The cell size adapts to the largest frame and smaller frames are centered in their cells. For clean animations, though, keeping every frame the same size works best.
What are the size limits?
Up to 64 frames of 512×512 pixels each, and the final sheet can be up to 4096×4096. That covers everything from tiny pixel-art characters to large effect animations.
Are my images uploaded anywhere?
No. The maker runs entirely in your browser — your sprites never leave your device. Need the reverse? Use our Sprite Sheet Splitter to cut a sheet back into frames.
