Resizer
A Windows batch image resizer that actually does what you need — point it at folders, walk through subfolders, and resize everything in one go.

Microsoft's PowerToys Image Resizer is great, but it always bugged me that you had to manually select individual files, there was no way to just say "go through this entire folder and all its subfolders and sort it out." So I built one that does exactly that.
You drop your folders in, pick a size preset (or set your own), choose how you want the output organised, and hit go. It'll walk through everything recursively, resize in parallel, and leave your originals untouched if that's what you want. It also, like PowerToys ImageResizer, preserves the original file timestamps and image metadata like EXIF data by default.
Built with .NET 8 and WPF, using ImageSharp under the hood for the actual resizing. Nothing ground-breaking, just a tool that was missing and needed to exist.
