How to use Convert JSON to a Data URI
- 1. Paste your JSON. Drop the JSON object or array you want to embed into the input pane. It converts as soon as it lands, so you can watch the data: URL take shape on the right while you edit.
- 2. Choose an encoding. Pick Base64 for a compact string that works anywhere a URL is accepted, or Percent-encoded to keep the JSON mostly readable inside the URL itself, which helps when debugging by eye.
- 3. Decide whether to minify first. Turn on Minify JSON first to strip whitespace before encoding, producing the shortest possible URL. Leave it off if you want the original formatting preserved inside the decoded string.
- 4. Copy the data: URL. Copy the finished data:application/json string and paste it wherever a URL is expected, such as an href, an import statement or a config value that points at inline data.
When to use Convert JSON to a Data URI
Convert JSON to a Data URI turns a JSON payload into a self-contained data: URL, so the data travels as a string instead of a separate file or network request. It is for the moments a JSON blob needs to live inside a URL, an attribute or a single config field.
- Embedding config in a script tag. You want a small JSON config available to a page without an extra fetch. Encode it as a data: URL and reference it from a script src or an import() call.
- Mocking an API without a server. A prototype needs a fake endpoint response but there is no backend yet. A data: URL of the JSON can stand in as the fetch target during local development or a demo.
- Passing structured data through a URL field. Some tools only accept a single URL string, like an iframe src or a bookmarklet. Encoding a small JSON structure as a data: URL lets you smuggle it through that one field.
- Sharing a JSON fixture as one copyable line. Instead of attaching a file to a ticket, paste a single data: URL that a teammate can open directly in a browser tab to see the decoded JSON content.

About the Convert JSON to a Data URI tool
Convert JSON to a Data URI is a free online tool that works entirely inside your web browser. Convert a JSON data structure to a data: URL. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 90 JSON utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Encoding and Minify JSON first, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Convert JSON to a Data URI free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
