How to use Uudecode a String
- 1. Paste the uuencoded block. Enter a full uuencoded block, starting with a begin line and ending with an end line, into the input pane, exactly as it appeared in the original file or email.
- 2. Read what the tool computes. Uudecode a String parses the begin header, decodes each encoded line back into raw bytes using the classic Unix-to-Unix character mapping, and stops at the end marker.
- 3. Copy the decoded text. Copy the recovered plain text out of the output pane, restoring the original content that had been encoded into the uuencoded block.
When to use Uudecode a String
Uudecode a String reverses uuencoding, a decades-old scheme once used to attach binary data to plain-text email and Usenet posts. Use it whenever you find an old begin and end block and need to recover the text it represents.
- Recovering an attachment from an old email archive. You are digging through an archived Unix mailbox and found a uuencoded block that an old client used to attach a file to a plain-text email.
- Decoding a Usenet post fragment. An archived Usenet newsgroup post contains a uuencoded block, a common way binary files were shared before MIME attachments became standard.
- Studying a legacy encoding format. You are learning about pre-MIME encoding schemes and want to see exactly how a uuencoded block decodes back into the original bytes.
- Verifying a script's uuencode output. You wrote or found a script that produces uuencoded output and want to confirm it round-trips correctly by decoding its result back to the original text.

About the Uudecode a String tool
Uudecode a String runs as plain JavaScript in your browser tab, with no server behind it. Convert Unix-to-Unix data to a string. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's String Tools section, 159 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. A worked example further down the page shows exactly what the tool produces for a real input.
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 Uudecode a String 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.
