SpriteFrame — Turn character images & frames into game-ready sprite sheets

About SpriteFrame

A sprite sheet maker for game developers and pixel artists. Upload a full-body character, describe the motion (idle, walk, run, attack, etc.), and AI generates the animation frames. You can also combine your own PNG frames or extract frames from an MP4 in the browser. Export a PNG sheet or frame sequence with JSON timing for Godot, Unity, or other engines. Freemium.

Who it is for
Game developers and pixel artists who need animation sprite sheets for engines like Godot and Unity.
Problem it solves
Building sprite sheets and animation frames by hand is slow and tedious, and getting frame timing into a game engine takes extra work.
The solution
Upload a full-body character, describe the motion (idle, walk, run, attack, etc.), and AI generates the animation frames. You can also combine your own PNG frames or extract frames from an MP4 in the browser, then export a PNG sheet or frame sequence with JSON timing.
What makes it unique
It turns a single character image into game-ready sprite sheets, and exports JSON timing for Godot, Unity, and other engines.

Features

  • Three ways to make a sprite sheet

    A sprite sheet keeps animation frames together in one image. Choose the SpriteFrame workflow that matches the assets you already have.

  • Animate a character image

    Upload one character image, describe a movement, and create animation frames. This option requires an account and credits.

  • Combine PNG frames

    Bring existing PNG frames, arrange their order, preview the motion, and export a sheet. Basic conversion needs no account.

  • Extract frames from MP4

    Choose a clip and frame count, extract frames in your browser, then turn them into a sprite sheet.
