The Case for HTML as the Global Standard for Contracts
June 2026 · 8 min read · By Evans Selasi Adika
HTML has been the backbone of the internet since 1991. It is structured, searchable, browser-native, and open. We make the case that it should be the default format for every contract written from this point forward.
A Brief History of Contract Formats
1990s: Contracts were typed on word processors and printed. The paper copy was the original. The digital file was a convenience.
2000s: Word became the drafting standard. Contracts were emailed as .doc attachments. Track changes became the collaboration tool. But the format was proprietary, and the files were not searchable across portfolios.
2010s: PDF became the storage standard. Signed contracts were scanned and saved as PDFs. Organisations accumulated thousands of PDFs that no system could search, parse, or extract from.
2020s: AI arrived. It could draft contracts in seconds — but the output was still .docx or PDF. The format problem was not solved. It was accelerated.
Why HTML
Structured by design. HTML uses tags to define structure. A heading is a heading. A paragraph is a paragraph. A clause can be tagged as a clause. This is not possible in PDF or Word without external annotation.
Searchable natively. Every browser on earth can search HTML. No plugins. No special software. Full-text search across thousands of documents is trivial.
Machine-readable. AI models understand HTML structure natively. They can distinguish between a heading and body text, between a clause and a schedule, between a defined term and its definition.
Browser-native. No software required. Open a browser. Open the contract. Edit, collaborate, sign. No installation. No licensing. No compatibility issues.
Open standard. HTML is maintained by the W3C. It is not owned by any company. It cannot be deprecated, discontinued, or paywalled. A contract written in HTML today will be readable in 2050.
Extensible. HTML can be extended with custom attributes and data fields. An obligation can carry metadata — bearer, deadline, consequence, risk level — directly in the document markup.
The Objections
“But we need Word for track changes.” HTML supports track changes natively through semantic redlining. Pactum’s engine provides word-level visual diffs.
“But counterparties expect .docx.” Pactum exports to .docx with one click. Draft in HTML, export in any format.
“But our CLM uses PDF.” That is the problem Pactum solves. Convert your CLM’s output to HTML. Make it searchable. Make it machine-readable.
The Standard
HTML has existed since 1991. It powers every website on earth. It is the most widely supported document format in history.
There is no reason the most important document in business should be in any other format.
