Real Image Compressor

Real Image Compressor does what other apps only pretend to do: it truly compresses your JPEG photos instead of simply resizing them. You stay in full control of quality, metadata, and output. Why "real" compression matters Most photo compression apps just scale down your images. That changes the resolution and often ruins the photo. Real Image Compressor applies actual JPEG compression algorithms that significantly reduce file size while keeping your original resolution intact. You are in control Choose from three quality levels (Low, Medium, High) to find the perfect balance between file size and image quality. Decide whether to strip EXIF metadata like location data, camera info, and timestamps for added privacy, or keep it all. Multiple ways to compress Pick photos directly from your Photo Library or import from Files. You can also select images in the Photos app and share them straight into Real Image Compressor using the Share Sheet. No extra steps needed. See real results After compression, you get a clear overview of every image: original size, compressed size, and the percentage saved. In our tests, photos typically shrink by 60-75%. Save anywhere Export your compressed images back to the Camera Roll or save them to any folder using the Files app. Batch export all images at once with a single tap. Privacy first All compression happens on your device. Your photos are never uploaded anywhere. Optionally remove EXIF data to strip location info and other metadata before sharing your photos with others. Key Features True JPEG compression, not just resizing Three quality levels: Low, Medium, High EXIF metadata removal for privacy Import from Photos or Files Share Sheet integration for quick access Batch compression for multiple images Clear results with size comparison Export to Camera Roll or Files 100% on-device processing Download Real Image Compressor and start saving storage space today.
