We present a detailed analysis of the best-quality multi-wavelength data gathered for the large-scale jet in the core-dominated quasar 3C 273. We analyze all the archival observations of the target with the Chandra X-ray Observatory, the far-ultraviolet observations with the Hubble Space Telescope, and a 8.4 GHz maps obtained with the Very Large Array. In our study we focus on investigating the morphology of the outflow at different frequencies, and therefore we apply various techniques for the image deconvolution, paying particular attention to a precise modeling of the Chandra and Hubble point spread functions. We find that the prominent brightness enhancements in the X-ray and far-ultraviolet jet of 3C 273 - the "knots" - are not point-like, and can be resolved transversely as extended features with sizes of about $\simeq 0.5$ kpc. Also, the radio outflow is wider than the deconvolved X-ray/ultraviolet jet. Finally, the intensity peaks of the X-ray knots are located systematically upstream of the corresponding radio intensity peaks; the distribution of the projected spatial offsets along the jet, ranging from $\lesssim 0.2$ kpc up to $\simeq 1$ kpc, seems to reflect to some extent a wiggling/curved appearance of the outflow. We discuss our findings in the wider context of multi-component models for the emission and structure of large-scale quasar jets, and speculate on the physical processes enabling an efficient acceleration of the emitting ultra-relativistic electrons along the entire jet length that exceeds 100 kpc.
