About Quoted Printable Encoder
Quoted-Printable, or QP encoding, is an encoding using printable ASCII characters (alphanumeric and the equals sign '=') to transmit 8-bit data over a 7-bit data path or, generally, over a medium which is not 8-bit clean. It is defined as a MIME content transfer encoding for use in email. QP works by using the equals sign '=' as an escape character. It also limits line length to 76, as some software has limits on line length.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: text.

Input
café
Result
caf=C3=A9

Before interpreting the result
Choose a decoder for an encoded payload, an encoder for transport, or a converter for structured data. Hex and Base64 represent bytes; converting formats does not encrypt or authenticate them.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
