Pixel Art Sprite Sheet Frame Extractor & GIF Creator
A professional-grade, client-side utility designed for game developers and digital artists. This tool allows users to import sprite sheets, define grid parameters, isolate frames, and compile animations into GIFs entirely within the browser.
Core Features
- Precision Grid Slicing: Define frame width, frame height, and column/row offsets to perfectly slice sprite sheets.
- Real-Time Preview: Instantly view the extracted frame grid or the animated sequence.
- Animation Controls: Reorder frames, delete unwanted frames, and set global or individual frame delays (in ms).
- High-Quality Export: Generate optimized animated GIFs directly in the browser.
- Interactive Canvas: Use a mouse-based interface to visualize slice boundaries on top of the original image.
UI Layout
- Header: Contains the tool name and primary action buttons (Upload, Clear, Export GIF).
- Main Tool Area:
- Left Sidebar: Controls for defining frame width/height, horizontal/vertical padding, and animation speed.
- Center Canvas: The main working area displaying the loaded sprite sheet with a resizable, draggable grid overlay for frame isolation.
- Right Panel: A frame gallery list showing all isolated frames. Includes 'Remove' icons and 'Drag to Reorder' functionality.
- No-Alert Policy: Custom UI modals are used for file processing errors, export confirmations, and instructions.
Design & Aesthetics
- Color Palette: Clean, professional light mode.
- Background: #F8FAFC
- Primary: #4F46E5 (Indigo)
- Secondary: #E2E8F0 (Gray)
- Text: #1E293B (Slate)
- Micro-interactions: Subtle hover states for the frame gallery items, smooth transition animations when the grid updates, and a responsive loading spinner overlay for heavy export tasks.
Technical Directives for Developer
- Architecture: Single HTML file containing CSS and JS.
- Libraries: Use a reliable CDN for a lightweight GIF encoder (e.g., gif.js or similar). Keep dependencies minimal.
- Environment Constraints:
- NO Storage: Do not use
localStorage,sessionStorage, or IndexedDB. State is managed via in-memory objects. - NO External Tracking: The application must be 100% private. No third-party tracking scripts.
- Iframe Ready: The app must function perfectly inside a sandboxed iframe with a
nullorigin. Use standard Blob URLs for image processing. - Responsive Design: Ensure the grid and frame gallery stack vertically on mobile and expand into a flexible three-column layout on desktop.
- NO Storage: Do not use

Frequently Asked Questions
Everything you need to know about using this application.
How does the sprite sheet frame extractor work?
The application allows you to upload your local sprite sheet image and define the frame width and height. It uses the HTML5 Canvas API to mathematically grid your image, isolating each individual frame based on your specific dimensions. Because this process happens entirely client-side, no images are ever sent to a server. You retain full control over your assets, and the tool processes the grid layout instantly to create a previewable sequence of frames.
Can I create an animated GIF from my sprite sheet?
Yes, once your frames are extracted, the tool provides an animation timeline. You can select specific frames, reorder them, and adjust the frame duration (milliseconds) to achieve the desired animation timing. After setting your animation sequence, the app utilizes a local GIF encoding library to generate a downloadable GIF file. This entire compilation process occurs within your browser tab, ensuring fast speeds without network lag.
Does this tool save my pixel art or project data?
This application is built with strict privacy in mind and does not use cookies, local storage, or any database. Your sprite sheets and extracted frame data exist only in the volatile memory of your browser tab. As soon as you refresh the page or close your browser, all temporary data is discarded automatically. We cannot access your files, and no persistent data is stored on our end.
What image formats and sizes are supported?
The tool supports standard PNG and JPEG sprite sheet formats. PNGs are highly recommended to preserve transparency, ensuring your pixel art remains clean and compatible with game development workflows. While there is no hard limit on image size, performance depends on your browser's memory capacity. Most standard game sprite sheets will process quickly, but extremely large high-resolution sheets may require more system resources to slice and animate.
