Ashampoo is selling Zoom 2 for $15, Zoom 3 for $20 [$15 upgrade], and Zoom 3 Pro for $40 [$30 upgrade]. Franzis is selling Zoom 2 Pro for $19 [includes Photoshop compatible plugins], but wants $99.99 for Zoom 3 Pro. The giveaway uses the Ashampoo app, and it looks like the two Zoom 3 apps from Ashampoo use it too, which may be a big downside, depending on how you feel about adding a bit of unnecessary bloat. I was able to get Ashampoo Zoom 2 working without the app after installing it in a VM, but I don't want to publish a how-to since it involves copying registry entries & files with the license activation or registration data, and *to me* that's over the line of what's permissible.
Zoom, as the name implies, is software to enlarge photos/images. It says Zoom 2 uses AI, but I think it's more along the lines of pre-AI machine learning, which as a plus keeps the size to a manageable 78MB -- AI software tends to start at ~1GB & go up from there. Zoom 2 is also fast -- quite a bit faster than Aiarty Image Enhancer for example. That said, I didn't see any signs of alterations, with the photo looking just like the original, with no degradation or improvement. It does allow you to save files in other formats besides .jpg -- not all of these apps do.
The Ashampoo app uses .NET & Webview 2, which means a Lot of smaller files. Zoom 2 OTOH follows Franzis standard format, though I believe it was written by a subcontractor, with the program's folder, a couple of folders in Users\ [UserName]\, and a folder in Users\ [UserName]\ AppData\ Local\. Like most all Franzis apps it installs Microsoft C/C++ runtime files, but itself only adds a couple of keys to the registry.
