How to use it
- Enter text.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
The text becomes UTF-8; every byte outside printable 33 to 126, or equal to =, is written =XX in hex. A space at the end of a line is encoded, and lines longer than 76 characters are split with a trailing = soft break.
Example
Result: Quoted-printable: =D9=85=D8=B1=D8=AD=D8=A8=D8=A7 =D8=A8=D9=83=D9=85; Lines: 1.
مرحبا بكم
=D9=85=D8=B1=D8=AD=D8=A8=D8=A7 =D8=A8=D9=83=D9=85
Limits and caveats
- Lines are shown with LF; mail software turns them into CRLF when sending.
- Text is always encoded as UTF-8, so declare charset=utf-8 in the message header.
Questions about this tool
Why does each Arabic letter become six characters like =D9=85?
An Arabic letter takes 2 bytes in UTF-8 and each byte is written =XX, which is why Base64 suits long Arabic emails better.
What does = at the end of a line mean?
It is a soft line break: the line was split only for length, and the break is removed when decoding.
Why is = itself encoded?
It starts every =XX code, so a literal = is written =3D to avoid confusion.
