PTGui is a panorama photo stitching program for Windows and macOS developed by New House Internet Services BV. PTGui was created as a GUI frontend to Helmut Dersch's Panorama Tools. It features its own stitching and blending engine^[2] along with compatibility to Panorama Tools. PTGui supports telephoto, normal, wide angle and fisheye lenses^[3] to create partial cylindrical up to full spherical panoramas. PTGui can handle multiple rows of images.^[4]

Originally released for Windows, version 6.0.3 introduced support for Mac OS X.^[5]

The 'free trial version' of PTGui is fully functional but creates panoramas with embedded visible watermarks.^[6]

PTGui Pro also includes HDR and tone mapping support.^[7]
