What quality should I expect from the HTML output?

Our converter preserves as much fidelity as HTML Document allows. Where LaTeX Document carries information that HTML Document cannot represent, that information is mapped to the closest equivalent (for example, color spaces, codec parameters, or metadata fields). For most everyday uses the result is indistinguishable from the source.

Are styles, images, and tables preserved when converting TEX to HTML?

Most styling is preserved: headings, paragraphs, lists, basic tables, and inline images. Complex elements like advanced table formatting, footnotes, or custom theming may shift slightly because LaTeX Document and HTML Document use different document models. Always review the HTML output before sending it on, especially for documents that depend on precise layout.

What file size should I expect for the HTML output?

The output size depends on the content and the compression characteristics of HTML Document. In most cases the HTML file will be in the same ballpark as your TEX input, with differences driven by how each format encodes data. There is no fixed ratio — the converter does not change quality settings unless you ask it to.

When should I convert TEX to HTML instead of staying with TEX?

Convert when the application, device, or workflow you are targeting prefers HTML Document over LaTeX Document. If your current TEX file already opens and behaves correctly everywhere you need it to, there is no benefit to converting — keep the original. The most common reasons to switch are compatibility (a tool only accepts HTML), distribution (recipients expect HTML), or feature requirements specific to HTML Document.

What is the maximum TEX file size I can convert?

MegaConvert accepts TEX files up to 100 MB on the free service, which is enough for the vast majority of real-world LaTeX Document files. If you have a larger file (typical for high-resolution video or uncompressed audio), please contact us — we can sometimes accommodate larger uploads for legitimate use cases.

Is my TEX file safe and private when I upload it?

Yes. Your TEX file is uploaded over HTTPS, processed in an isolated job environment, and deleted from our servers within one hour. We do not read, index, store, or share the contents of your file. No account is required, so the upload is not associated with a personal identity. See our privacy policy for the full details.

Why Convert TEX to HTML?

Understand when and why this conversion makes sense for your workflow.

Converting LaTeX Document to HTML Document addresses one of the most practical challenges in modern work: sharing and editing documents across different platforms and applications. Document formats vary widely in how they store text, images, fonts, and layout — meaning a file that looks perfect in one program may render incorrectly in another. Converting to the right format ensures that your content is either fully editable or perfectly preserved for distribution, depending on what you need.

LaTeX Document has a known limitation: steep learning curve with complex markup syntax. In contrast, HTML Document offers a key advantage: universal rendering in all web browsers on every platform. While LaTeX Document is commonly used for academic papers, theses, and dissertations, HTML Document is better suited for web pages and web application interfaces.

MegaConvert handles the TEX-to-HTML conversion automatically, preserving your document's structure and content as faithfully as the formats allow — no software installation required.

How to Convert TEX to HTML

Follow these simple steps to convert your file in seconds.

Upload your TEX document
Select your .tex file from your computer. LaTeX Document documents — including those with embedded images, tables, footnotes, and complex layouts — are supported. Larger documents may take a moment longer to parse before conversion begins.
Click "Convert to HTML"
Press the convert button. We parse the structure of the LaTeX Document document — text, headings, lists, tables, images — and rebuild it in HTML Document format. Fonts are embedded where the target supports it. The conversion typically completes in a few seconds.
Wait for the document to render
Most document conversions finish in under five seconds. Complex documents with many embedded images, tables, or footnotes may take a little longer to render — the converter takes the time it needs to preserve formatting accurately.
Download your .html file
When the conversion finishes, click the download link to save the new HTML Document file to your computer. The file is yours — no watermarks, no expiration on the file itself, and no MegaConvert account is required to download it.

Tips for Converting TEX to HTML

Practical advice to get the best results from this conversion.

Why this conversion is worth doing

LaTeX Document has a known limitation: steep learning curve with complex markup syntax. HTML Document addresses this with a key advantage: universal rendering in all web browsers on every platform. Converting from TEX to HTML is most worthwhile when this specific trade-off matters for the way you intend to use the file.

Match the format to the actual workflow

LaTeX Document is most commonly used for academic papers, theses, and dissertations, while HTML Document is the standard for web pages and web application interfaces. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where TEX is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.

Watch for this limitation in the HTML output

HTML Document has its own limitation worth understanding before you commit: appearance varies across different browsers and screen sizes. After the conversion completes, open the HTML file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.

Understand the editing vs. viewing trade-off

Some document formats are designed for editing (DOCX, ODT), while others are intended for final distribution (PDF). Converting to PDF locks in your formatting and makes it difficult to edit the content later. If you plan to revise the document further, keep an editable source copy before converting.

Understanding TEX and HTML Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

LaTeX Document

application/x-tex

TeX/LaTeX is a typesetting system and document preparation language developed by Donald Knuth (TeX) and Leslie Lamport (LaTeX), widely used in academia for producing high-quality scientific and mathematical documents. LaTeX uses markup commands to define document structure and formatting, excelling at complex mathematical notation, bibliographies, and cross-references. It produces publication-quality output, typically compiled to PDF.

Advantages

Superior typesetting quality, especially for mathematical formulas and equations
Automated handling of references, citations, cross-references, and bibliographies
Consistent, professional output suitable for academic publication

Limitations

Steep learning curve with complex markup syntax
Not WYSIWYG; requires compilation to see the final output
Difficult to collaborate on with non-technical users

Common Uses

Academic papers, theses, and dissertations
Scientific and mathematical publication typesetting
Technical books and research documents

Target Format

HTML Document

text/html

HTML (HyperText Markup Language) is the standard markup language for creating web pages and web applications. It defines the structure and content of documents using tags, and can incorporate CSS for styling and JavaScript for interactivity. HTML documents are rendered by web browsers and serve as the foundation of the World Wide Web.

Advantages

Universal rendering in all web browsers on every platform
Supports rich content including text, images, links, and multimedia
Can be styled with CSS and enhanced with JavaScript for interactivity

Limitations

Appearance varies across different browsers and screen sizes
Not suitable for precise print layout without additional CSS
Raw HTML is verbose and not easy to read as a document format

Common Uses

Web pages and web application interfaces
Email newsletters and HTML-formatted messages
Online documentation and help systems
