How to use Convert UTF7 to UTF8
- 1. Paste the UTF-7 text. Enter the UTF-7 encoded string, such as Hi +Jjo- where the plus sign opens a shifted, modified base64 run for the smiley character it wraps.
- 2. Let the tool unwind the shifted runs. There are no settings here; the tool detects each plus-sign shift sequence, decodes the modified base64 inside it, and leaves plain ASCII characters untouched as it rebuilds UTF-8 text.
- 3. Copy the decoded UTF-8 string. The output pane shows the readable result, for example Hi followed by a smiley face. Copy it into your editor or mail client.
When to use Convert UTF7 to UTF8
Convert UTF7 to UTF8 decodes the mail-safe encoding defined in RFC 2152, designed so Unicode text could travel through systems that only trusted 7-bit ASCII. It is rare today but still turns up in old email headers and legacy IMAP servers, and this tool unwinds the shifted base64 runs back into normal characters.
- Reading an old email header field. An email header from a legacy mail server encodes a subject or folder name in UTF-7 instead of the more common quoted-printable or base64 MIME encoding. Decoding it here reveals the actual text.
- Debugging an IMAP mailbox name. IMAP historically encodes non-ASCII folder names using a UTF-7 variant, and a mail client shows the raw encoded string. Pasting it here turns it back into the readable folder name.
- Investigating a security scanner flag. A web security tool flags UTF-7 encoded input as a potential XSS bypass technique from older Internet Explorer versions. Decoding the sample here shows exactly what payload it was hiding.

About the Convert UTF7 to UTF8 tool
Convert UTF7 to UTF8 runs as plain JavaScript in your browser tab, with no server behind it. Convert UTF7 data to UTF8 data. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's UTF-8 Tools section, 69 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 Convert UTF7 to UTF8 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.
