What are the differences and advantages of using .h5 files over .npy files or vice versa?

I have a huge collection of images and I converted them into '.npy' and '.h5' format but the resulting size of folders of h5 and npy files are way more than that of the size of original images. What's the reason behind this? I also want to know the advantages of using both the file formats and differences between them.

Robert Schaefer

h5 and npy add structure (useful for adding metadata to images), the usefulness (or not) depends on your intent and purpose.
