@keirFox in addition to the other suggestions below, silent data corruption like this could also be a byproduct of bad RAM. memtest86+ is the go-to tool here, you can likely do sudo apt install memtest86+ and then it will show up in your GRUB boot menu next time you reboot; letting it run for 24H is the ideal but usually seriously misbehaving RAM reveals itself in just one run
what filesystem are you using? what kind of hard drive is all this happening on? (e.g. ssd, nvme ssd, spinning rust)
do all the affected files exist in one specific directory (e.g. a photo library) and do you know if you have any kind of indexing scanner thing running on them? is it affecting any non-image files?

@qualia @keirFox Seconding this - my motherboard had incompatibility with the RAM modules and it would silently corrupt RAM on standby/resume. This meant that any files which had been loaded from disk into memory cache could wind up "corrupted"… And memtest86+ didn't report issues because it was only on standby/resume. That drove me nuts, and is why I switched to BTRFS on my next install (nowadays ZFS is an option too).
