Overleaf Compile Timeout Fix: Researcher Triage Guide

First move: Compress raster images, export plots as PDF or SVG, and compile once in draft mode.

First move: Externalize diagrams or include generated PDF/SVG outputs while writing.

First move: Check bibliography logs, reduce unnecessary style work, and compile a minimal reference test.

First move: Use includeonly or chapter-level compiles, then run full compiles at checkpoints.

First move: Keep the LaTeX source as fallback and test a Typst migration on one section first.

% Use lower resolution images
\includegraphics[width=0.8\textwidth]{image.jpg}
% Instead of large PNGs

% Remove unused packages like:
% \usepackage{tikz}  % if not using diagrams
% \usepackage{minted} % if not using code highlighting

\documentclass[draft]{article}
% Images show as boxes, but compiles fast

% main.tex
\includeonly{chapter1} % Only compile chapter1
\include{chapter1}
\include{chapter2}

% Add to preamble:
\usepackage{mylatexformat}
\endofdump
% Then compile once, subsequent compilations are faster

Cloud LaTeX editors use compile time limits to manage shared compute. Large figures, TikZ diagrams, custom fonts, heavy bibliographies, and full-thesis compiles are common causes.

Sometimes a different plan or local compile environment gives more headroom, but the safer first step is still to isolate the slow document component and reduce unnecessary compile work.

TikZ (especially with complex diagrams), minted (syntax highlighting), fontspec (custom fonts), and large bibliographies are the main culprits.

TypeTeX supports a browser-first Typst editing path for fast preview loops, plus LaTeX import paths for researchers who need to keep a migration fallback.

Paid plans don't make compilation faster, they just allow more time before timeout. The same document takes the same time to compile.
