Code-Parth/image-optimization ? reverse-engineered prompt

Build me a small Python tool that can take the images in my project and turn them into WebP files.

It should work on single files or whole folders, go through subfolders when I ask, and keep the same relative folder structure in the output. Please skip SVGs, already optimized WebP files, and anything unknown by default. I want it to be safe too, so don’t overwrite anything unless I explicitly say so.

Use ffmpeg with libwebp, and if that is missing, show me a clear message telling me what I need instead of trying to install things on its own. Add a dry run option, a lossless mode for logos and screenshots, and a quality setting for photos. It would also be great if it could print a simple before and after report with file sizes and total savings, and optionally write that report to JSON.
