SpriteFrame creates game-ready sprite sheets and animation frames from character images, PNG sequences, or video clips using AI and browser tools.
What it is
SpriteFrame is a web-based utility designed for game developers and artists to build, preview, and export sprite sheets. It offers multiple workflows to turn static images, existing PNG sequences, or MP4 video clips into organized game assets complete with JSON timing data.
Key features
- Generate AI sprite animations from a single character image and movement description
- Combine existing PNG frames and reorder them into a cohesive sheet
- Extract individual frames from MP4 video clips directly in the browser
- Automatic background removal and edge correction for generated characters
- Built-in motion preview to check loops, playback order, and frame sizes
- Export assets as PNG sprite sheets, numbered frames, GIFs, or ZIP archives with JSON timing reference
Who it's for
This utility suits indie game developers, pixel artists, and designers who need to quickly prepare character animations for engines like Godot and Unity without manual sprite sheet stitching.
Pricing
SpriteFrame offers a free tier with 30 signup credits and free basic PNG and MP4 conversion tools. Paid monthly subscriptions include the Basic plan at $12 per month and the Pro plan at $29 per month, which provide larger monthly credit allowances for AI generation.
