Free LaTeX Tools
The complete guide to FormaTeX's free online LaTeX tools. Convert documents to six different formats, render equations and diagrams to images, format source code, and generate tables — all from your browser, no account required.
This page covers every tool available on the platform: what it does, when to use it, and how to get started. Whether you need a quick DOCX export for a collaborator or a high-resolution PNG of a TikZ diagram for a presentation, there is a tool for that.
\section{Why online tools}
Why use online LaTeX tools?
A full LaTeX installation can weigh several gigabytes, and setting up Pandoc, Inkscape, or ImageMagick for document conversion adds more complexity. Online tools eliminate all of that. You paste or upload your LaTeX source, pick a target format, and get the result in seconds. There is nothing to install, no dependencies to manage, and no command-line flags to remember.
This matters most when you need to share your work with people who do not use LaTeX. A thesis supervisor may want a Word document. A conference website may accept only HTML. A slide deck may need a high-resolution equation image. Instead of wrestling with local toolchains every time, you can convert directly from the browser.
FormaTeX offers 11 free tools organized into three categories: document conversion, rendering, and formatting. Every tool runs server-side with a full TeX Live installation, so the output quality matches what you would get from a local build. The tools are also available through the REST API for programmatic access.
\section{Conversion tools}
Document conversion
Convert your LaTeX source into six widely used document formats. Each converter compiles your document server-side, then transforms the output using Pandoc and other conversion engines. Upload companion files like images and .bib bibliographies alongside your main .tex file for accurate results.
LaTeX to DOCX
Convert LaTeX documents to Microsoft Word format. This is the most popular conversion tool on the platform — ideal for sharing papers with collaborators who use Word, or for submitting to journals that require DOCX uploads. Tables, equations, figures, and citations are preserved in the conversion.
LaTeX to HTML
Transform LaTeX source into clean, semantic HTML. Use this when you need to publish a paper or thesis on the web. The converter produces valid HTML5 with MathML or MathJax-compatible equation markup, so formulas render correctly in any modern browser.
LaTeX to EPUB
Generate EPUB e-books from LaTeX source. The EPUB format is supported by every major e-reader including Kindle, Kobo, and Apple Books. This converter is useful for turning long-form documents like textbooks, lecture notes, or dissertations into reflowable e-book format.
LaTeX to Markdown
Convert LaTeX to Markdown for use in GitHub READMEs, wikis, static site generators, or note-taking apps like Obsidian and Notion. The converter handles section headings, lists, emphasis, code blocks, and inline math notation.
LaTeX to Plain Text
Strip all LaTeX markup and produce clean plain text. This is useful for word counts, plagiarism checks, accessibility reviews, or feeding document content into NLP pipelines and language models that do not understand LaTeX syntax.
LaTeX to ODT
Convert to OpenDocument Text format for LibreOffice, Google Docs, and other office suites that support the ODF standard. ODT is the ISO-standardized alternative to DOCX, and some European institutions require it for official submissions.
\section{Rendering tools}
Rendering and visualization
Render LaTeX fragments — equations, diagrams, and chemical structures — to high-resolution images. These tools are designed for situations where you need a standalone image rather than a full document: embedding a formula in a slide deck, adding a TikZ diagram to a web page, or generating molecular structures for a chemistry paper.
Equation to Image
Paste a LaTeX math expression and get a transparent PNG or SVG. Supports display math, aligned environments, matrices, and every symbol from the AMS math packages. Choose your resolution, font size, and foreground color. Perfect for presentations, blog posts, and social media.
Equations guideTikZ to Image
Render TikZ and PGF diagrams to PNG or SVG without compiling a full document. This tool supports all standard TikZ libraries — arrows, automata, positioning, calc, decorations — and compiles with pdfLaTeX or LuaLaTeX. Ideal for flowcharts, graphs, neural network diagrams, and geometric constructions.
TikZ guideChemistry Diagrams
Render chemical structures, reaction schemes, and molecular diagrams using the chemfig and mhchem LaTeX packages. Input your structure code and get a publication-quality image. Supports Lewis structures, skeletal formulas, reaction arrows, and orbital diagrams.
\section{Formatting tools}
Formatting and generation
Two tools that help you write cleaner LaTeX faster. The formatter tidies up messy source code, and the table generator creates LaTeX table markup from a visual spreadsheet-style interface — no syntax required.
LaTeX Formatter
Paste messy LaTeX source and get cleanly indented, consistently formatted output. The formatter normalizes whitespace, aligns environment delimiters, and applies consistent brace style. Useful for cleaning up code before submission, enforcing a house style across co-authored documents, or simply making your source easier to read and maintain.
Table Generator
Build LaTeX tables visually. Enter your data in a spreadsheet-like grid, configure column alignment, borders, and header styles, then copy the generated LaTeX code. Supports booktabs formatting for publication-quality tables. Much faster than writing tabular markup by hand, especially for large data tables.

\section{API access}
Using the API
Every tool on this page is also available through the FormaTeX REST API. This means you can integrate LaTeX compilation and conversion directly into your own applications, CI/CD pipelines, or automation scripts. Generate API keys from your dashboard and start making requests immediately.
The API accepts LaTeX source as a string or file upload and returns the converted output. All endpoints follow the same pattern: send your LaTeX, specify the target format, and receive the result. Rate limits and compilation quotas depend on your plan.
