Quoted-Printable Decoder

Summary

Paste quoted-printable encoded text and instantly decode it back to plain, human-readable text.

How it works

1. Paste your quoted-printable encoded text into the input field.
2. Select the character encoding (UTF-8 is correct for most modern emails).
3. Click "Decode" — the tool strips soft line breaks (trailing =) and converts =XX hex pairs to their byte values.
4. The decoded plain text appears in the output panel.
5. Use "Copy Output" to copy the result to your clipboard.

Use cases

• Recovering readable text from malformed or partially encoded messages.
• Verifying that an email client is encoding special characters correctly.
• Converting QP-encoded multilingual content to Unicode for further processing.
• Inspecting encoded attachments or inline content in MIME messages.
