Privacy & Security
All image compression and processing happens entirely in your browser using HTML5 Canvas API. Your images never leave your device - no uploads to any server, no data collection, completely private and secure.
Tips: Lower quality values reduce file size more but may affect image quality. WebP format typically offers the best compression ratio. Keep original aspect ratio by setting only width or height.
