A few more details

Good questions. Clear answers.

The essentials before you start.

Which method should I choose?

Exact enlarges without AI. Clarity also sharpens existing edges. Enhance (AI) estimates additional detail on-device. Contains AI-estimated detail. Exact and Clarity change nothing: they enlarge only what is already in your photo. Inspect before exporting.

Will it work on my Mac?

One universal app for Intel and Apple silicon; Rosetta is not needed. Support for macOS 12 and later is planned; the current test build has been tested only on macOS 26.6. See System requirements.

Do my images leave my Mac?

No images are uploaded for processing. The app sends no telemetry. Licence activation and a roughly monthly licence recheck connect online; neither is a payment renewal.

Can it turn a thumbnail into a hero image?

Yes, in dimensions: a 275-pixel long edge becomes 2,200 pixels at 8×. Exact and Clarity use no regenerative AI: they enlarge existing information, leaving soft detail soft. Enhance (AI) estimates missing detail so the result can look more like a hero image. Contains AI-estimated detail. Check it at 100 % before you export. For print, ask your printer for pixel dimensions and PPI: a 2,400-pixel image is 8 inches wide at 300 PPI. Dimensions do not guarantee usable detail.

What does US$29 include?
