TIL: arXiV-ready LaTeX files from Overleaf

One persistent problem I often come across is how the LaTeX files from Overleaf that I upload to arXiv have source or compatibility errors. Today, I learned that instead of downloading the zip archive to get the LaTeX source, I should use the “Submit” button.

Don’t click the archive button:

Instead, go to your Overleaf project > Submit > Submit Your Papers to ArXiV:

This creates an optimized zip file that is 100% compatible with arXiv!
