Animator

A native desktop application that converts sprite sheets into CSS animations, HTML code, and GIF exports. Built with Wails for cross-platform performance.

Sprite animation workflows have traditionally been fragmented and time-consuming. Developers manually write CSS keyframes, calculate frame positions, and iterate through trial-and-error processes to achieve smooth animations. Web-based tools often struggle with performance limitations, especially when handling large sprite sheets or providing real-time preview capabilities.

Animator bridges this gap by providing an intuitive desktop environment where sprite sheets transform into production-ready web animations through visual configuration rather than manual coding. The application automatically detects sprite dimensions, suggests optimal grid layouts, and generates multiple export formats including CSS classes, HTML examples, ZIP packages, and high-quality GIF files with transparency support.

Perfect for game developers working with character sprites and UI elements, web designers integrating animated assets into digital experiences, digital artists creating AI-generated sprite sheets, and development teams requiring consistent animation workflows with standardized output formats.

Core Features

Smart Grid Detection

Automatically analyzes uploaded sprite sheets and suggests optimal grid configurations. Adjustable columns, rows, margins, and manual positioning controls ensure precise frame extraction from any sprite layout.

Real-Time Animation Preview

Live CSS-based animation preview with adjustable frame rates, loop modes, and ping-pong playback. See exactly how animations will perform in browsers before exporting any code.

Multi-Format Export

Generate CSS keyframes, HTML usage examples, complete ZIP packages, and high-quality GIF files with transparency support. All exports are production-ready and optimized for web deployment.

Multiple Animation Management

Handle multiple animations within a single sprite sheet. Configure individual frame counts, switch between animations seamlessly, and export each as separate CSS classes or files.

Precise Control Features

Advanced positioning controls support negative offset values and zoom functionality for large sprite sheets. Manual start and end position coordinates ensure pixel-perfect frame extraction. Project auto-save to localStorage with JSON import/export capabilities preserve work sessions and enable team collaboration.
