About Image Compressor

A professional-grade batch image optimization suite. Upload up to 50 images and compress them with precision — choose between JPG, PNG, WebP, and AVIF output formats, or use Smart Auto mode which tries every format and picks the smallest file automatically. Fine-tune lossy quality with a slider (1–100) or switch to lossless mode. Set a max dimension to resize large photos, toggle metadata stripping, and preview results with an interactive before/after compare slider with zoom. See exactly how much space you saved with a real-time stats bar. Download individual files or bulk-export everything as a ZIP. Supports drag-and-drop, file browse, and clipboard paste (Ctrl+V). All processing happens 100% in your browser — your images never leave your device.
