How to use Convert Data URI to ASCII
- 1. Paste your data URI. Paste the full data: URI string, including the data: prefix and MIME type, into the input pane. Both base64 and percent encoded payloads are recognized.
- 2. See the payload unpacked. The tool strips the scheme and MIME type prefix, then decodes the payload, base64 or percent encoded, to recover the original text hidden inside the URI.
- 3. Copy the decoded text. Copy the plain text result once the URI has been unpacked. Paste a different data URI to decode another payload right away.
When to use Convert Data URI to ASCII
Convert Data URI to ASCII unpacks a data: URI, the inline format browsers and email clients use to embed small text or binary payloads directly in a document, back into readable text. Instead of manually stripping the MIME type prefix and running the payload through a base64 decoder, paste the whole URI and get the content immediately.
- Inspecting an embedded resource in HTML. A web page or email embeds a small text file directly as a data: URI inside a src or href attribute. Pasting the URI here shows exactly what content is embedded without opening dev tools.
- Debugging a base64 encoded config value. A configuration file or environment variable stores a small snippet as a data URI for portability. Decoding it confirms the actual text before you trust it in a deployment.
- Checking a QR code or share link payload. Some tools generate data: URIs to pass short text through a QR code or URL. Decoding the URI verifies the message matches what you intended to share.
- Auditing a suspicious link. A data: URI appears in a phishing email or suspicious script and you want to see its contents before clicking anything. Pasting it here reveals the plain text safely, without loading it in a browser.

Hi
About the Convert Data URI to ASCII tool
Convert Data URI to ASCII is a free online tool that works entirely inside your web browser. Decode a data: URI back into plain ASCII text. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 81 ASCII utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
There is nothing to configure. Provide the input and the result appears on its own. 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
Does Convert Data URI to ASCII cost anything?
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?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
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?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
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.
