Professional AI Upscaling, Right on Your Mac
AI Image Upscaler Pro is a professional-grade desktop application that uses advanced neural networks to enhance, enlarge, and restore your images — all running entirely locally on your Mac. Powered by state-of-the-art Real-ESRGAN technology, it delivers stunning upscaling results without the privacy risks or ongoing subscription costs of cloud-based services.
Whether you are a photographer recovering lost detail in low-resolution shots, a digital artist upscaling textures and game assets, or someone restoring old family photos, AI Image Upscaler Pro handles it all with specialized AI models optimized for each use case — up to 8x resolution, in bulk, entirely offline.

Real-ESRGAN AI Models
Three specialized built-in models — each fine-tuned for a different type of image content for the best possible upscaling results.
Real-ESRGAN Photos
Optimized for real-world photographs. Recovers fine details, textures, and sharpness in portraits, landscapes, and product shots without over-sharpening.
Real-ESRGAN Anime
Specifically trained on anime and illustrated content. Preserves clean lines, flat colour regions, and stylized edges without introducing photographic artifacts.
Real-ESRGAN Digital Art
Tuned for computer-generated imagery, textures, game assets, and concept art. Maintains artistic intent while significantly increasing output resolution.
Flexible Scaling — 2x to 8x Resolution
Choose your exact output scale to match your workflow requirements. From a modest 2x boost for web assets to a full 8x enlargement for large-format print or detailed texture work.
Key Features
100% Local & Private
Your images never leave your Mac. All processing runs entirely on your local hardware — zero cloud uploads, zero server queues, zero privacy risk.
Apple Silicon Accelerated
Automatically detects and uses your Mac’s GPU for maximum processing speed. Includes an optimized CPU fallback to ensure compatibility across supported macOS systems.
Batch Processing
Upscale entire folders of images in one automated batch while you work on other tasks. Ideal for processing large asset libraries, photo archives, or texture sets.
Up to 8x Upscaling
Choose from 2x, 3x, 4x, 6x, or 8x resolution scaling to match your exact output requirements — from web-ready assets to large-format print-ready files.
Background API Service Pro
Run the upscaler as a headless background service exposing a local or network REST API — similar to Ollama. Integrate AI upscaling into your own scripts, workflows, and pipelines without opening the UI.
Custom .pth Model Import Pro
Import your own trained or community .pth model files. Supports RRDBNet and SRVGGNetCompact architectures so you can use any compatible Real-ESRGAN-based model.

Frequently Asked Questions
Are my images sent to the cloud for processing?
No. The developer has confirmed that no data is collected from this app. All upscaling runs entirely on your Mac’s hardware — your images never leave your computer at any point.
Which AI model should I choose?
Use the Photos model for real photographs — portraits, landscapes, product shots. Choose the Anime model for illustrated characters, manga panels, or cel-shaded artwork. Select Digital Art for computer-generated imagery, game textures, and concept art.
Does this work on Intel Macs?
No. The app requires Apple Silicon (M1 or later) to leverage Metal GPU acceleration. It is not compatible with Intel-based Macs.
What does the Background API Service do?
The Pro API Service runs the upscaler as a headless background process and exposes a local or network REST API endpoint — similar in concept to how Ollama works for LLMs. You can send upscaling requests from your own scripts, automation tools, or third-party software without needing to open the app UI.
What custom model formats are supported?
Pro subscribers can import .pth model files compatible with the RRDBNet and SRVGGNetCompact architectures — the two most common Real-ESRGAN model architectures used in the community. This lets you use any publicly available or personally trained upscaling model.
Can I cancel my Pro subscription?
Yes. Pro subscriptions are managed through your Apple Account and can be cancelled at any time via App Store settings. You retain Pro access until the end of your current billing period, then revert to the full base app features.
