PhotoZoom Pro

The software enlarges and downsizes digital photos and graphics using a patented S‑Spline Max AI interpolation algorithm, which claims to produce higher‑quality enlargements and smoother reductions. Users can specify any target dimension up to one million pixels on a side, and the tool automatically reduces JPEG compression artifacts and noise during processing.

It offers a range of presets for different image types, as well as fine‑tuning options that let users create custom resize profiles. A split‑screen preview lets users compare results side‑by‑side, and a crop tool assists in creating close‑ups. Batch processing enables resizing of multiple files in a single operation.

The application runs as a stand‑alone program on macOS and is also available as a plug‑in for Photoshop, Photoshop Elements, Corel PHOTO‑PAINT, Corel PaintShop Pro, and as an integration with Lightroom Classic, supporting both print and on‑screen workflows.
