Overleaf extension

Fix LaTeX errors without leaving Overleaf.

One click compiles your project, finds the figure overflow, broken floats, wide tables and compile errors, and writes the fix back into your editor.

Using a custom or university class? Upload a .zip that includes your .cls file alongside your .tex - that's how we detect your document class correctly.

No .cls file? We'll auto-detect the class from your \documentclass and the document type you pick below.

Conference or journal submission - strict float & layout rules.

We'll explain whether the tool caught what you described.

You review before anything is written. Every fix shows a diff, and Overleaf keeps full history, so you can undo anytime.

!Compile errors

Undefined commands, missing packages, mis-nested environments

[]Figure overflow

Scales images to fit your column, no distortion

#Table overflow

Resizes or spans to full width automatically

@Reference check

Verifies every DOI via CrossRef, flags bad citations

<Direct write-back

Changes appear in your open editor, no download

// real example

Exactly what it changes

A two-column IEEE paper. Two lines changed: the figure stops overflowing and stops pinning itself in place.

Before - what you uploaded

1\begin{figure}[H]
2 \centering
3 \includegraphics[width=\textwidth]{robot_arm.png}
4 \caption{Forward kinematics diagram.}
5 \label{fig:fk}
6\end{figure}

After - what you download

1\begin{figure}[t]
2 \centering
3 \includegraphics[width=\columnwidth]{robot_arm.png}
4 \caption{Forward kinematics diagram.}
5 \label{fig:fk}
6\end{figure}

figure_width

\textwidth β†’ \columnwidth

In a two-column layout, \textwidth is the full page width - your figure overflows into the margin. \columnwidth is the correct column width.

float_placement

[H] β†’ [t]

[H] forces the figure exactly here, causing huge whitespace gaps when the figure doesn't fit. [t] lets LaTeX place it at the top of the next suitable column.

Everything it catches

Deterministic layout fixes, plus compile errors and dead citations.

Figure overflow

width=1.3\linewidth -> 0.95\linewidth

Bad float placement

[H] -> [t]

Table overflow

auto \resizebox to \columnwidth

Missing labels

adds \label{fig:results}

Unreferenced figures

flags figures with no \ref

Wrong figure order

fixes float drift

Who it is for

Researchers who know LaTeX but do not have time to debug it.

Conference authors

NeurIPS, ICML, CVPR, ICLR, ACL

Strict page limits and figure placement rules, hours before the deadline.

Journal authors

IEEE, Springer, Nature, Elsevier

Column-width constraints and a different template for every journal.

Thesis writers

PhD and Master's theses

Hundreds of pages with dozens of figures to keep consistent.

Grant writers

NSF, NIH, DOE, ERC

Hard page limits and reviewer-friendly layout, fast.

What researchers are saying

From PhD students racing deadlines to professional thesis editors.

β€œFixed all 6 figure overflow issues in my NeurIPS submission in 30 seconds.”

Priya S.

PhD student, Machine Learning

NeurIPS
β€œSaved me an hour before the ACM deadline. The two-column table fix alone was worth it.”

James K.

Postdoc, Systems Research

ACM
β€œI format 20+ theses a year. The batch feature cut my turnaround from 2 hours to 15 minutes.”

Frequently asked questions

What researchers ask before their first pre-submission check.

How can I check my paper before submission?+

Upload your .tex project to LaTeX Formatter. It scans for figure overflow, wide tables, float-placement problems, equation overflow, and reference issues, then returns a corrected file and a plain-English changelog - usually in under 60 seconds.

Can invalid DOIs cause problems during review?+

Yes. A dead or mistyped DOI sends reviewers to a broken link and signals a rushed submission. Include your .bib and LaTeX Formatter verifies every DOI against CrossRef, flagging dead DOIs and titles that do not resolve to a real record.

Will it change my writing or content?+

No. Every fix is rule-based and scoped to formatting only: figure width, table sizing, float placement, equation formatting. Your text, math, and citations are never touched. Every change is listed in the changelog so you can review it before applying.
