Overleaf Compile Timeout Fix: 10 Solutions That Actually Work

Frustrated by "Compilation timed out" errors? Here's how to get your LaTeX documents compiling again—plus a permanent solution.

Last updated: March 19, 2026

The Problem: Overleaf's 10-Second Limit

If you're seeing Compilation timed out errors, you've hit Overleaf's free tier limit. Since 2024, free accounts are restricted to 10 seconds of compilation time per document.

Error: Compilation timed out

Your compile has been cancelled because it reached the time limit for your plan

This affects: thesis chapters, papers with figures, documents with TikZ diagrams, large bibliographies, and anything using custom fonts.

Quick Fixes (Try These First)

1. Optimize Images
Compress images before uploading. Use JPG instead of PNG for photos.
% Use lower resolution images
\includegraphics[width=0.8\textwidth]{image.jpg}
% Instead of large PNGs
2. Remove Unused Packages
Each package adds compilation time. Remove packages you don't actually use.
% Remove unused packages like:
% \usepackage{tikz}  % if not using diagrams
% \usepackage{minted} % if not using code highlighting
3. Use Draft Mode
Draft mode skips image rendering, dramatically speeding up compilation.
\documentclass[draft]{article}
% Images show as boxes, but compiles fast
4. Split Large Documents
Use \input or \include to compile chapters separately.
% main.tex
\includeonly{chapter1} % Only compile chapter1
\include{chapter1}
\include{chapter2}
5. Precompile Preamble
Use mylatexformat to create a precompiled format file.
% Add to preamble:
\usepackage{mylatexformat}
\endofdump
% Then compile once, subsequent compilations are faster

Advanced Optimizations

Externalize TikZ Graphics
TikZ diagrams are a major cause of timeouts. Externalize them to compile once and cache.
\usetikzlibrary{external}
\tikzexternalize[prefix=figures/]
% TikZ figures are now cached as PDFs
Use Simpler Bibliography
Large bibliographies slow compilation. Use biber with restricted processing.
% In your preamble:
\usepackage[backend=biber,maxbibnames=3]{biblatex}
% Limit names shown to reduce processing
Reduce Font Loading
Custom fonts add significant compilation time.
% Use standard fonts instead of:
% \usepackage{fontspec}
% \setmainfont{CustomFont}
% Use Computer Modern (default) or Times
Optimize Tables
Complex tables with many cells slow down compilation.
% Use simpler table packages
\usepackage{booktabs}
% Instead of complex tabularx or longtable when not needed

The Permanent Solution

Switch to TypeTeX (No Timeout Limits)

Instead of fighting Overleaf's limits, consider TypeTeX—a modern LaTeX editor with no compile timeout restrictions, even on the free tier.

Overleaf Free

  • • 10-second compile limit
  • • Complex documents fail
  • • Must pay $21/month for more
  • • Same slow compilation speed

TypeTeX Free

  • • No timeout limits
  • • Any complexity works
  • • Free forever
  • • Typst: sub-second compilation

TypeTeX supports both Typst (recommended—compiles in milliseconds) and LaTeX (for compatibility). Import your Overleaf projects directly.

Frequently Asked Questions

Why does Overleaf have a 10-second timeout?

Overleaf limits free tier compilation to 10 seconds to manage server resources. This was increased from 20 seconds in 2024. Premium plans ($21/month) get 4-minute timeouts.

Can I increase the timeout without paying?

No, the only way to increase timeout limits is to upgrade to a paid plan or optimize your document to compile faster.

Which packages cause the most timeout issues?

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

Is there an Overleaf alternative without timeout limits?

Yes! TypeTeX offers unlimited compilation time on the free tier, plus uses Typst by default which compiles in milliseconds instead of seconds.

Will my document compile faster on a paid Overleaf plan?

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