WebHandBrake exposes 3 profiles for H.264 Encodes. You can think of the profile as the level of complexity required in encode / decode. The higher the complexity, the more CPU power is needed to encode/decode. Setting a profile, constrains the encode to using settings that are allowed for that profile level.
