How they compare
Pornhub is the best-known free tube, with a huge library, verified models and polished apps, but heavy ads and blocks in many US states and some countries. Pornhub Premium is the paid version: no ads on Pornhub, HD and 4K streaming, exclusive originals and VR, and downloads.
Premium costs from about $9.99 a month, less on a yearly plan, and prices vary by country. Much of the catalogue is free on Pornhub anyway, so you're mostly paying for no ads, better quality and the exclusives.
