An ultra-fast, privacy-focused image optimizer that runs entirely in your browser.
ChoiConvert is a tool born out of necessity. As a developer/creator, I constantly needed to optimize images for the web, but existing online tools were either slow, ridden with ads, or uploaded my private files to their servers.
I built this tool to solve those problems with a focus on speed, privacy, and aesthetics.
- 🚀 100% Client-Side: No server uploads. Your images never leave your device.
- ⚡ Instant Conversion: Converts PNG and JPEG files to WebP in milliseconds.
- 📂 Batch Processing: Drag & drop multiple images and convert them all at once.
- 🎛️ Smart Optimization:
- Global Quality Slider: Fine-tune compression levels to balance size and quality.
- Smart Resizing: Automatically scale down 4K+ images to web-friendly native resolutions (e.g., 1920px, 1280px).
- 🎨 Premium Design: A modern, glassmorphic UI with smooth animations and dark mode support.
- 📉 Real-Time Savings: Instantly see how much space you're saving before downloading.
- Core: Vanilla HTML5, CSS3, JavaScript (ES6+)
- Styling: Custom CSS variables, Glassmorphism, CSS Animations
- Logic: HTML5 Canvas API, File API, Blob objects
