Opening note — TEX is a LaTeX source document, a programmable typesetting format for mathematical and technical writing. The HTML you want is two clicks away. Converting TEX to HTML keeps the document's content but changes how it is distributed. LaTeX Document may be the right editing format; HTML Document may be the right delivery format (or vice-versa). KaijuConverter renders the document through a LibreOffice + pandoc pipeline so headings, paragraphs, lists, tables, images and hyperlinks survive the round-trip intact. Context: TEX is a LaTeX source document, a programmable typesetting format for mathematical and technical writing. HTML is the web's HyperText Markup Language, the universal document format for browsers.
LaTeX Document
Source formatLaTeX is a document preparation system for high-quality typesetting of scientific papers.
HTML Document
Target formatHTML is the standard markup language for web pages. As a conversion target or source, it carries text content with structural and formatting information that can be extracted or repurposed.
Why convert TEX to HTML
TEX and HTML both describe paginated text, but they target different parts of the document life cycle. TEX is usually editable; HTML is usually final. Converting is about moving from editing to distribution (or the other way round) without losing headings, styles, tables or embedded images along the way.
HOW TO CONVERT
TEX → HTML
Upload your TEX
Drop the document onto the uploader. We transfer over HTTPS and keep the file in an isolated processing container.
Render with LibreOffice
LibreOffice opens the TEX headlessly and writes it as HTML with styles, tables and images mapped across.
Download the HTML
The HTML is ready to download; typography, pagination and embedded assets match what you saw in the source.
Common Use Cases
Corporate collaboration
Most enterprise pipelines expect HTML; arriving with TEX triggers "what format is this?" conversations and conversion delays.
Cloud co-editing
Google Docs and Office Online open HTML with formatting intact; TEX often triggers a conversion step that drops styles.
Legal and regulatory filing
Courts, government portals and compliance systems accept HTML as the canonical format — TEX may be rejected outright.
Academic submission
Journals, universities and grant portals specify HTML for manuscripts, theses and proposals in their submission guidelines.
Quality & Compatibility
LibreOffice handles the heavy lifting and maps the overwhelming majority of TEX features to their HTML equivalents. Standard system fonts (Arial, Calibri, Times, Helvetica) transfer exactly; corporate or custom fonts are substituted with the closest available match, which can shift line breaks by a character or two. Inline images embed at original resolution.
Tips for Best Results
- Embed fonts in the TEX before uploading if you use non-system fonts — it guarantees the HTML renders identically on any viewer.
- Check tables, figure captions and page headers after conversion; complex layouts occasionally need a minor nudge in the target application.
- For documents with a table of contents, refresh the TOC field after opening the HTML so page numbers reflect the new pagination.
Frequently Asked Questions
Frequently Asked Questions
Yes, as long as the fonts are standard (system fonts or common office fonts like Arial, Calibri, Times, Helvetica). Custom corporate fonts survive if they are embedded in the source document; otherwise the conversion substitutes the closest available match, which can shift line breaks by a character or two.
Yes. Inline images are embedded into the HTML at full resolution, editable tables become native HTML tables, and hyperlinks keep their URLs. Complex features unique to TEX — macros, form fields, track-changes — are mapped where an equivalent exists in HTML and flattened into static content otherwise.
All uploads go over TLS, files are processed in isolated containers and both the source and the output are deleted within two hours. No account is required, file contents are never indexed or used for training, and the paid plan adds a signable data-processing agreement for regulated workflows.
