Create GIF Animation
Create high-quality GIF animations from multiple images with custom size, speed, and effects
Click or drag to upload image files
Supports JPG, PNG, WebP, BMP formats, max 10MB per file
Creation Instructions
- • Image Requirements: Supports JPG, PNG, WebP, BMP formats, recommend same aspect ratio
- • File Size: Max 10MB per image, total size recommended under 50MB
- • Frame Count: 2-100 frames, too many frames may affect performance and file size
- • Quality Settings: Higher quality = larger files, choose appropriate quality for your needs
- • Playback Effects: Supports loop playback and ping-pong effect (back and forth)
- • Privacy Protection: All processing is done locally in your browser, files are not uploaded to servers
🎨 Creation Tips
Quality Animation
- • Use sequential images with good continuity
- • Maintain consistent image dimensions and aspect ratios
- • Appropriate frame delay (300-800ms)
- • Keep total frame count under 50
File Optimization
- • Moderate dimensions (400-600px)
- • Adjust quality settings based on usage
- • Avoid overly complex backgrounds
- • Test different settings to find optimal balance
⚙️ Technical Details
Using gif.js library + Web Workers:
- • Multi-threaded Processing: Uses Web Workers for parallel processing without blocking the page
- • Smart Scheduling: Automatically adjusts worker count based on device performance and frame count
- • Color Quantization: Intelligently reduces color count to optimize file size
- • Dithering Algorithm: Uses dithering techniques to maintain visual quality
- • Progressive Rendering: Real-time processing progress display
- • Memory Optimization: Processes frame data in batches to prevent memory overflow
💡 Performance Advantage:Using local Web Workers files avoids network latency, multi-threaded parallel processing significantly improves GIF generation speed, while maintaining smooth page responsiveness.
