APKmirror only hosts APKs that matches the vendor digital signature, you won’t find modified stuff there. So in terms of safety it’s as safe as the Play Store itself.

We make sure that the cryptographic signatures for new versions of all previously published apps match the original ones, which means we know if uploaded APKs were signed by the real devs or someone pretending to be them.
