Will it damage my amp to plug in from the output of a headphone amp?

Might be a dumb question:

I have a Mooer Audiofile on the end of my amp-less board, but would find it convenient sometimes to go straight from its 1/4 inch output out to my amp (Boss Katana).

I know nothing about electronics and I'm just wondering whether or not the extra voltage(?) that can drive headphones will harm the amp or not.

Thanks.
