Topaz Photo — Mac download

Topaz Photo is a desktop image-enhancement app that sharpens, denoises, and upscales photos using AI-based tools.

Sharpening that targets the real culprit

Soft images come from three places: camera shake, motion blur, and missed focus. The sharpening module addresses each directly. It rebuilds edge definition without introducing halos or crunchy artefacts, so a handheld shot at dusk tightens up without looking oversharpened.

Denoising that respects the detail

High-ISO noise and fine texture often sit in the same part of the histogram. The denoising module isolates noise from actual image detail, cleaning up shadows and skies while keeping hair, fabric, and foliage intact. Pair it with the upscaling tool to enlarge a clean file six times—useful for prints and tight crops where resolution falls short.

Drag a folder to queue, preview only what you click

Drag a folder straight onto the app window to queue its contents. No import dialog, no browsing. The preview pane updates only the region you click—press Space to re-render the full frame after a parameter change. That skips unnecessary processing while you tweak sliders.

Hold Option while dragging the comparison slider to snap it to preset splits: 50/50, 25/75, and 75/25. Helpful when you want a consistent before/after view across multiple images. The auto-upscale toggle remembers your last multiplier per session, so a batch of crops inherits the same output size without reconfiguring.

If you work with raw files, double-click a thumbnail to open the masking brush. Paint over the areas you want the model to prioritize—useful when the subject is sharp but the background is the problem, or vice versa.

Wonder 3.5 cleans up fur and weathered text at high enlargement

The Wonder 3.5 model replaced the default upscaling engine. In practice, it handles low-contrast edges—think fur against dirt, or text on weathered paper—with fewer artefacts than earlier models. You notice it most at 4× and 6× enlargements where older versions sometimes introduced a painterly smoothness.

Removing the Neuroserver output-size restriction means batch jobs no longer cap large exports. A 24-megapixel file upscaled to 4× runs locally without stalling at an artificial ceiling. That change alone shortens multi-image sessions for print work.

New camera profiles for the Sony A7RV, A7RVI, and Alpha 9 III mean the app reads their raw noise signatures more accurately. Files from those bodies require less manual slider work on import. Bug fixes tidied up occasional preview freezes when switching models mid-session.

Version 1.7.1 ships with the developer's latest fixes and improvements. Full details are in the release notes on the Topaz Labs site.
