Systems and methods are disclosed for a format agnostic document viewer with document translation that provide the ability for a user to either select a portion of the viewed document text in the format agnostic viewer and have it translated into a selected language, or for the user to have the entire document presented in the format agnostic viewer in translated form. The translated text may be shown side-by-side with the original document text in the format agnostic viewer, or can replace the original text on the visible page in the format agnostic viewer. The translated text may be formatted according to, or displayed with, some enhancements to account for differences in the original text and translated text or other differences.
