Tips for Accurate PDF to LaTeX Conversion

Follow these best practices to get the most accurate results from our AI-powered converter.

Use High-Resolution PDFs

For scanned documents, aim for at least 300 DPI resolution. Higher resolution gives the OCR engine more detail to work with, significantly improving recognition accuracy for small subscripts and complex symbols.

Ensure Clear Contrast

Dark text on a light background produces the best results. Avoid faded photocopies or low-contrast scans. If your PDF has a colored background, converting to grayscale first can help.

Check Complex Layouts

While we support multi-column formats and floating elements (figures, tables), very dense layouts may occasionally need manual review. The tool provides a side-by-side preview for easy verification.

Verify Output Before Publishing

Always review generated LaTeX code before using it in publications. Our AI achieves high accuracy, but mathematical notation can be ambiguous — a quick human check ensures correctness for formal documents.

Use With Our LaTeX Editor

After conversion, paste the extracted LaTeX into our free online LaTeX Editor for instant preview, editing, and formatting adjustments. It's the perfect workflow: extract → preview → edit → export.

Frequently Asked Questions

Common questions about PDF to LaTeX conversion.

What types of PDFs work best?

High-resolution PDFs (300 DPI or higher) with clear contrast work best — both native text-based and scanned documents are fully supported. AI-powered OCR handles printed mathematical formulas with over 95% accuracy.

How accurate is the formula recognition?

Our AI-powered math OCR achieves over 95% accuracy on well-printed mathematical formulas, including complex equations, fractions, matrices, integrals, and Greek letters. Dense layouts may benefit from manual review.

Can I edit the generated LaTeX?

Yes! Download as a complete .tex file ready for Overleaf, TeXShop, or any LaTeX editor, or copy the source code directly. We recommend using our free LaTeX Editor for instant preview and editing after conversion.

Is my PDF data sent to external servers?

No. All processing runs entirely in your browser. No PDF files or content are uploaded to external servers.

What is the maximum file size?

Supports PDF files up to 200 MB, suitable for entire research papers, textbooks, and lecture notes with multiple pages and complex layouts.

Can I convert scanned PDFs?

Yes! Our AI OCR engine fully supports scanned and image-based PDFs. For best results with scanned documents, use at least 300 DPI resolution and ensure clear contrast between text and background.

What document classes are supported?

The tool generates LaTeX using the article class by default. The code can be adapted for report, book, or beamer classes.

Is this service free?

Completely free with unlimited conversions — no signup, no credit card, no trial limits. Unlike paid alternatives that require subscriptions and impose usage caps, there are no hidden fees or usage restrictions.

Why should I keep the tab in the foreground during conversion?

Due to browser limitations, switching tabs may interrupt or slow down the conversion process. Please keep this tab active until conversion completes.

Does the tool use GPU acceleration?

When your browser supports WebGPU, GPU acceleration is automatically used for faster conversion. Check WebGPU browser support to see if your browser is compatible.

How long does model loading take on first use?

On first visit, the AI recognition model (approximately 400 MB) needs to be downloaded. The exact time depends on your network conditions — typically between a few seconds and a couple of minutes. The good news: the model only needs to load once. On subsequent visits, it will be read directly from your browser cache with no re-download needed. We've optimized model delivery via a global CDN to minimize your wait time as much as possible.
