A modern web application for creating beautiful before/after image comparisons with a draggable diagonal splitter and lossless export.
- Interactive Comparison: Draggable diagonal splitter with adjustable angles (-45° to +45°).
- High-Resolution Export: Download your results in PNG, JPEG, WebP, or AVIF formats at original image resolution.
- Precision Cropping: Fine-tune your images with pixel-perfect top, bottom, left, and right cropping.
- Customizable Splitter: Adjust the divider's color, width, and shadow to match your aesthetic.
- Solid Color Infills: Use solid colors as an alternative to images for either the "Before" or "After" slots.
- Responsive Design: Optimized for both desktop and mobile devices with touch support.
"This tool was born from a lack of high-quality image comparison utilities and a desire to explore the full capabilities of the JetBrains July Agent. It was built using 'vibe-coding' techniques to create a seamless user experience."
