UpscaleKit
Upscale photos and illustrations, locally
Enlarge photos and illustrations right on your Mac — private, precise, with no image upload. UpscaleKit pairs local Core ML models with a pixel-accurate preview, so you can see exactly what the model changed.
Requires macOS 15 or later, Apple-silicon native. Your originals are never overwritten.

What it does
Enlarge, compare, export
Local AI upscaling
Core ML models run on Apple silicon. Let UpscaleKit analyse the image and pick a model, or choose one yourself and compare models with coupled zoom.
See the difference
A live preview and a draggable split line put original and result side by side, with pixel rulers and precise zoom.
Frame it
Crop, straighten, and apply pre- and post-filters with a movable crop box before you export.
Batch and export
Drag-and-drop batch processing; export PNG, JPEG, TIFF and HEIC with colour space, bit depth and resolution metadata.
Bring your own model
Import your own compatible Core ML models and run them the same way.
Private by design
Your images stay on your Mac.
Image processing runs on-device. Only model downloads you start yourself need a connection — a one-time purchase, no subscription, no ads, no tracking.
