How to randomly pad files before encryption to prevent file fingerprinting? (lemmy.world)

Hi, I was planning to encrypt my files with GPG for safety before uploading them to the cloud. However, from what I understand GPG doesn't pad files/do much to prevent file fingerprinting. I was looking around for a way to reliably pad files and encrypt metadata for them but couldn't find anything. Haven't found any recommendations on the privacyguides website either. Any help would be appreciated!

Thanks

Yes. Security has trade offs. But cloud backup storage is cheap.

Is there no way to encrypt the metadata of files using GPG? And how do people pad their files to prevent fingerprinting? Surely I'm not the first person to be asking about this? I haven't had much luck searching online

GPG/PGP turns takes the file and turns it into random bits that only someone with the private key can unrandomize. There is no file metadata left. There is no nothing left. I believe the sizes are even consistent (0-1024kB files will be the same output size.)

The files metadata is encrypted with GPG. Except for GPG metadata, which is minimal
