What is Image Compression?
Image compression is the process of reducing the file size of an image while maintaining acceptable visual quality. Compressed images load faster on websites, use less bandwidth, and improve user experience. There are two main types of compression: lossless (no quality loss) and lossy (some quality loss for smaller file sizes).
Our Image Compressor uses lossy compression with adjustable quality settings, allowing you to find the perfect balance between file size and image quality. The tool uses the HTML5 Canvas API to process images entirely in your browser, ensuring your images never leave your device.

Image Formats Explained
JPEG: Best for photographs and images with many colors. Uses lossy compression, so quality decreases as file size decreases. Doesn't support transparency.
PNG: Best for images with transparency, graphics, and images with few colors. Uses lossless compression, so file sizes are typically larger than JPEG. Supports transparency.
WebP: Modern format offering better compression than JPEG and PNG. Supports both lossy and lossless compression, as well as transparency. Limited browser support in older browsers.
GIF: Best for simple animations and images with few colors. Limited to 256 colors. Supports animation and transparency.
