The study of multiwavelength emission properties of blazar jets has the potential to shed light on the particle acceleration and emission mechanisms taking place in them. The emission of PKS 2155-304 (z = 0.116) and S5 0716+71 (z = 0.31) bright blazars in the optical/UV, X-ray and γ -ray bands is investigated by analyzing data from Fermi-LAT, Swift XRT and Swift UVOT telescopes. The multiwavelength light curves of both sources in these bands show multiple peaks when the flux increased substantially. In the optical/UV bands, the flux of both sources increased above 2∙10-10 erg cm-2 s-1. The X-ray emission from PKS 2155-304 was characterized by a harder-when-brighter trend, whereas the γ-ray emission from S5 0716+71 showed a moderated trend of softer-when-brighter. The correlation analysis shows a strong correlation between the UV and γ-ray emission of PKS 2155-304, while there is a correlation between the optical/UV and X-ray emission of S5 0716+71. The observed broadband spectral energy distribution of both sources as well as the observed variability and correlations can be accounted for within one-zone synchrotron/synchrotron-self-Compton models.
