About Quoted-Printable
Quoted-Printable (RFC 2045) is an email transfer encoding that keeps ASCII text easy to read, while encoding non-ASCII or special bytes as "=" followed by two hex digits.
How it works: printable ASCII characters are left as-is; other characters (e.g. é, or "=") are written as =HH. This makes the result far more readable than Base64 for mostly-ASCII text.
Quoted-Printable is used in email headers and bodies (MIME) for text with few non-ASCII characters. It is ideal when readability matters more than compactness.
FAQ
Can this Quoted-Printable tool both encode and decode?
Yes. This is a single page with a toggle — use Encode mode to transform text, and Decode mode to reverse it. No need for two separate pages.
Is my data sent to a server?
No. Quoted-Printable is processed entirely in your browser. The text you enter never leaves your device.
