Store description excerpt
Image Ninja is the fastest way to batch convert and compress images on your Mac. Drop in your photos, pick your format, and let the ninja work its magic. POWERFUL FORMAT CONVERSION Convert between JPEG, PNG, and WebP formats with a single drag-and-drop. Whether you need WebP for web performance, JPEG for compatibility, or PNG for transparency, Image Ninja handles it all. INDUSTRY-LEADING COMPRESSION Unlike basic converters, Image Ninja uses the same encoding technology trusted by major tech companies: - MozJPEG for superior JPEG compression (up to 10% smaller than standard encoders) - Google's libwebp for optimal WebP output - Smart compression presets so you always know what you're getting SMART COMPRESSION PRESETS No confusing quality sliders. Choose from four clearly labeled levels: - None: Maximum quality, original file size - Low: Best visual quality with slight compression - Medium: Balanced quality and file size - High: Maximum compression for smallest files BLAZING FAST BATCH PROCESSING Convert hundreds of images at once. Image Ninja processes 3 images in parallel, dramatically speeding up bulk conversions compared to one-at-a-time tools. PRESERVES YOUR METADATA Your EXIF data matters. Image Ninja automatically preserves camera information, GPS coordinates, timestamps, and other metadata during conversion. 100% LOCAL & PRIVATE Your images never leave your Mac. No cloud uploads, no accounts, no subscriptions. Everything is processed locally on your machine.
