If you’ve ever worked with Atlassian products like Jira or Confluence Cloud, you’ve likely come across the mysterious Atlassian Document Format (ADF) — a JSON-based schema that powers how rich text and structured content are stored and rendered.

At first glance, ADF looks nothing like HTML. Instead of <p>, <strong>, and <ul>, you’ll find nested objects like "type": "paragraph" or "marks": [{"type": "strong"}]. But ADF isn’t just another markup language — it’s a purpose-built, structured representation of content designed for modern collaborative editing.

We’re excited to announce the launch of AdfKit, our comprehensive NuGet package that brings the full power of Atlassian Document Format (ADF) conversion directly to your .NET applications. While our API service has been serving thousands of developers worldwide, we recognized that many teams need the flexibility, performance, and security benefits that come with a local solution.

Why Choose AdfKit Over the API?

Enhanced Security & Privacy

With AdfKit, your sensitive documents never leave your infrastructure. Process confidential content, proprietary documentation, and sensitive data without worrying about external API calls or data transmission. Perfect for:

Introducing RTF to ADF Conversion: Expanding Document Format Support

We’re excited to announce a powerful new addition to the ADFAPI.dev platform: RTF (Rich Text Format) to ADF conversion. This latest endpoint expands our document conversion capabilities, making it easier than ever to migrate RTF documents into Atlassian’s ecosystem.

What is RTF and Why Convert to ADF?

Rich Text Format (RTF) is a widely-used document format that preserves text formatting across different applications and platforms. Developed by Microsoft, RTF files contain formatted text, images, and other document elements that can be opened by most word processors.

We’re excited to announce a new feature on adfapi.dev: you can now automatically render Atlassian Document Format (ADF) JSON into HTML, right in your browser.

For a while, adfapi.dev has been the go-to resource for developers working with the Atlassian Document Format — whether you’re building Jira or Confluence apps, integrating with the REST APIs, or just trying to understand how ADF works. Until now, the platform primarily focused on parsing, validating, and converting ADF through our API.

Working with Jira or Confluence often means dealing with Atlassian Document Format (ADF) — the structured JSON schema behind rich text content.

Manually writing ADF is tedious and error-prone. That’s where ADFAPI comes in: a hosted API that converts HTML or Markdown into clean, valid ADF.

In this post, we’ll show you how to use PowerShell to convert HTML to ADF JSON, both from a file and directly from a raw HTML string — and how to preview the results visually in your browser.

If you’ve ever needed to get your HTML into Jira or Confluence, you know the process isn’t exactly straightforward. Atlassian uses its own JSON-based document model called Atlassian Document Format (ADF). While ADF is flexible and powerful, generating it from HTML can be a hassle.

Fortunately, there are a few NPM libraries that attempt to bridge the gap and convert HTML into ADF. In this post, we’ll walk through what’s out there today, and also show you an alternative if you’d rather not spend time running and maintaining these libraries yourself.

Word to ADF Conversion Is Now Live on adfapi.dev!

We’re excited to announce a major new milestone for adfapi.dev: you can now convert Word documents (.docx) to Atlassian Document Format (ADF) — directly in your browser, with no signup required.

Just head to the Try It page, upload a Word file, and see the ADF JSON instantly. It’s never been easier to bring your existing content into Confluence, Jira, or any other Atlassian product that uses ADF.

Since launching adfapi.dev, our mission has been simple: provide a fast, reliable way to convert documents into the Atlassian Document Format (ADF) — with zero setup and no friction. We’ve been thrilled by the response and the wide adoption of the API across tools, workflows, and platforms.

To keep the service sustainable and continue improving it, we’re making a small change that takes effect starting August 1st.

What’s Changing?

Starting in August, any API requests without an API key will result in converted documents that include a short line of text:

If you’ve ever tried to programmatically create rich content in Confluence or Jira, you’ve likely come across a mysterious acronym: ADF — short for Atlassian Document Format. But what is ADF really, and why should it matter to your team, your documentation strategy, or your development workflow?

In this post, we’ll break down what ADF is, why it exists, and why understanding it can unlock powerful automation, migration, and integration capabilities across the Atlassian ecosystem.

Hello world! This is our first post!

Welcome to adfapi.dev If you’re looking for an easy way to convert documents to and from the Atlassian Document Format, then we can help you!

adfapi.dev was built to scratch an itch. Our team needed to migrate from Pivotal Tracker and Azure DevOps to JIRA. We looked for an API to do this, but couldn’t find one. We found some libraries, but the conversion was not complete and sometimes looked really weird. It also required a lot of manual work to fix the formatting issues.
