How many photos can I process at once on the website?

It depends on your computer’s memory: between 150 and 1,000 files and between 0.5 and 3 GB per batch. For bigger folders, the desktop app has no limits.

Is the subfolder structure kept?

Yes. The result mirrors the same subfolders, and your originals are never touched.
