Q&A

Why Not arxiv-latex-cleaner?

arxiv-latex-cleaner statically analyzes LaTeX source code, which has some limitations:

1. It does not reliably track dependencies in all scenarios—e.g., when images are included via complex macros that obscure their filenames in the source code.
2. It only supports fixed-size image rescaling, without considering how large an image appears in the final compiled PDF.

How Does arxivit Work?

arxivit takes a different approach:

• It uses latexmk to compile the LaTeX source code.
• It analyzes the compilation log to determine which .tex files and images are included, as well as their sizes in the final PDF.
• It rescales images to the desired DPI based on their actual dimensions in the final document, ensuring uniform sharpness while minimizing file size.
• It uses latexpand to strip comments from .tex files.
