>> frequently asked questions
What is Quoted-Printable encoding?
Quoted-Printable is a MIME content transfer encoding that allows 8-bit data to be transmitted over 7-bit email systems while keeping ASCII text human-readable.
When should I use Quoted-Printable?
Use Quoted-Printable for email messages containing mostly ASCII text with occasional special characters or international text. It's ideal when readability is important.
How does it differ from Base64?
Unlike Base64 which makes all content unreadable, Quoted-Printable keeps ASCII text readable and only encodes special characters, making it better for text-heavy content.
What does the '=' character mean?
The '=' character is an escape character in Quoted-Printable. It's followed by two hex digits to represent a byte, or used at line ends for soft line breaks.
