Bigger images. Smaller files. Your photos stay on your Mac.
Photo Upscaler combines AI image enlargement and image compression in one native Mac app. Enhance low-resolution photos, enlarge illustrations, or reduce file sizes for sharing and storage—all with local Apple Silicon processing.
Your images are processed entirely on your Mac without uploading to any cloud service. Enlargement and compression work completely offline, keeping your personal photos and work images strictly confidential.
Choose from AI models suited to everyday photos, faster processing, or illustrations. Adjust enlargement scales up to 16×, or utilize two-pass AI processing for a 4× followed by 4× high-detail enlargement.
Lossless optimization for PNG files without changing decoded pixels. Lossless or adjustable lossy compression for JPEG and static WebP. If compression does not reduce size, the original file is preserved.
Batch processing with memory-aware concurrency, interactive slider comparison, and non-destructive output. Made for Macs with Apple Silicon (M1 and later). Requires macOS 14.6 or later.
