DRAWIO File Format

Overview

DRAWIO files, with their .drawio extension, are digital diagrams created using diagrams.net , a powerful open-source tool for crafting visual content. These files encapsulate the essence of your diagram projects—layout, shapes, text, and images—all in one neat package. Whether you’re mapping out complex processes or organizing project flows, DRAWIO is designed to make your work visually appealing and easy to manage. The format supports a wide array of diagrams including flowcharts, organizational charts, maps, engineering schematics, process diagrams, and more.

DRAWIO files are particularly useful for teams looking to collaborate on visual content in real-time. They can be easily shared and edited across various platforms, making them an ideal choice for modern work environments where remote collaboration is the norm. With DRAWIO, you’re not just creating a static image; you’re building a dynamic tool that enhances communication and understanding within your team.

Technical Specifications

Format Structure

DRAWIO files are XML-based vector image files. They store diagram data in an XML format that can be easily parsed and manipulated programmatically. This makes DRAWIO files highly compatible with various tools and platforms that support XML parsing.

Core Components

Headers: Contains metadata about the file, such as version information and document properties.
Body: The main content of the file where diagram elements like shapes, text, images, and connections are defined.
Chunks: Individual components within the body section, each representing a specific element in the diagram.

Standards & Compatibility

DRAWIO files adhere to XML standards for data representation. They support multiple export formats such as JPG, PNG, BMP, PDF, HTML, and VSDX, ensuring broad compatibility across different applications and platforms.

History & Evolution

DRAWIO was first introduced by diagrams.net (formerly draw.io) in 2015 as a web-based diagramming tool. Initially designed to provide an easy-to-use interface for creating flowcharts and other types of diagrams, it quickly gained popularity due to its flexibility and real-time collaboration features.

Over the years, DRAWIO has evolved significantly:

2017: Introduced support for more complex diagrams like organization charts and process maps.
2019: Enhanced real-time editing capabilities, allowing multiple users to work on a single diagram simultaneously.
2021: Launched as an open-source project, making it accessible to developers who want to customize or extend its functionality.
