A paper, thesis or problem set written in LaTeX has to be produced as a PDF without installing a full TeX distribution.
The source is compiled, not converted. Macros expand, floats are placed, references resolve and the typesetter produces the fixed pages LaTeX is famous for.
A .tex file is rarely self-contained. It usually needs its bibliography, its class file, its figures and sometimes multiple compilation passes before cross-references and citations resolve. A single file converted alone will compile with question marks where every reference should be.
BibTeX has not run, or the second compilation pass has not happened. Reference resolution needs at least two passes.
Common CTAN packages are available. An exotic or locally modified class file has to travel with the source.

Portable Document Format is lossy, so the quality control decides the trade between size and fidelity.
Converted and deleted the moment it finishes. Never written to permanent storage.
