How to find broken pictures in a folder (Gif, Png, Jpeg), as well as PDF?

Question

System administration

After formatting the disk, we performed the file recovery procedure. We received tens of gigabytes of pictures and documents, most of which are broken files.
How and how can you sort files into valid and not (at least pictures)?
Any operating system.
