About

A startup-minded effort to rebuild documents for the web.

Lean Document Format is a format effort focused on compactness, editability, portability, and AI-native document behavior.

LDF is being shaped by what a modern document product actually needs to import, edit, present, share, and export.

The format is public, inspectable, and designed to be debated in the open instead of hidden behind vendors and viewers.

Accessibility, portability, collaboration, and compactness are baseline requirements, not nice-to-have extras.

What the project is trying to prove

Documents should not have to choose between compact distribution and real software ergonomics. LDF is an attempt to keep both.
