How to use Decode Data URI to Unicode
- 1. Paste the full data URI. Paste the full data URI you want decoded, including the data: scheme, MIME type, and either the percent-encoded or base64 payload.
- 2. See the MIME type and encoding parsed. The tool parses the MIME type and encoding declared in the URI header, then decodes the payload accordingly, whether it is percent-encoded or base64, back into plain Unicode text.
- 3. Copy the decoded text. Copy the decoded text and read the actual content the data URI was carrying, whether it came from a stylesheet, an inline script, or a browser's saved page source.
When to use Decode Data URI to Unicode
Decode Data URI to Unicode extracts the plain text hiding inside a data: URL, handling either its percent-encoded or base64 payload automatically. It is for whenever a data URI shows up in code or markup and you want to read what it actually contains.
- Reading an inline data URI in HTML source. A web page's source embeds a data:text/plain URI as a placeholder or comment, and decoding it here reveals the actual message without manually stripping the encoding by hand.
- Debugging a generated data URI from a script. A script you wrote generates a data URI, and decoding the output here confirms it encodes the exact text you intended before shipping the code.
- Inspecting a browser bookmarklet. A bookmarklet or shared snippet uses a data URI to store its source, and decoding it here lets you read what the script actually does before running it.
- Verifying a data URI copied from documentation. A tutorial or API doc shows a data URI as an example, and decoding it confirms it demonstrates the value the documentation claims before you copy the pattern into your own project.

About the Decode Data URI to Unicode tool
Decode Data URI to Unicode runs as plain JavaScript in your browser tab, with no server behind it. Convert a valid data URL to Unicode text. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Unicode Tools section, 98 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Decode Data URI to Unicode 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.
