PTGui Pro 12.9 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This software for Mac OS X is a product of New House Internet Services B.V.
The software lies within Design & Photo Tools, more precisely Viewers & Editors. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software.
From the developer:
PTGui is panoramic image stitching software for Windows and macOS. Originally started as a Graphical User Interface for Panorama Tools (hence the name), PTGui has evolved into a full featured, industry leading photo stitching application.
PTGui is blazing fast! Thanks to OpenCL GPU acceleration PTGui is able to stitch a 1 Gigapixel panorama in about 25 seconds on modest hardware.
