Questions about Photo Collage

Does Photo Collage upload my files?

No. Photo Collage runs entirely on your Mac, so your files never leave it and it works offline.

Will Photo Collage change my original files?

No. Results are saved as new files in a dated folder in Downloads › OneMacTools, and your originals are left exactly as they were unless you turn on an option that says otherwise.

What does Photo Collage need?

Just a Mac with macOS 26 or later. There's nothing else to install.
