Properties of the Higgs boson with mass near 125
are measured in proton-proton collisions with the CMS experiment at the LHC. Comprehensive sets of production and decay measurements are combined. The decay channels include 
, 
, 
, 
, 
, and 
pairs. The data samples were collected in 2011 and 2012 and correspond to integrated luminosities of up to 5.1
at 7 and up to 19.7 at 8. From the high-resolution and channels, the mass of the Higgs boson is determined to be 
. For this mass value, the event yields obtained in the different analyses tagging specific decay channels and production mechanisms are consistent with those expected for the standard model Higgs boson. The combined best-fit signal relative to the standard model expectation is 
at the measured mass. The couplings of the Higgs boson are probed for deviations in magnitude from the standard model predictions in multiple ways, including searches for invisible and undetected decays. No significant deviations are found.
