Image Optimizer

Compress, convert, and resize images directly in your browser. Drop a batch of PNG / JPEG / WebP files, pick an output format and quality, and download the optimized set as a ZIP. Files never leave your device — everything runs locally via the browser's canvas encoder. EXIF metadata is stripped automatically.
