MIME Decoder
How MIME Decoding Works
MIME encoded-words are parsed and decoded using the specified encoding.
- 1
Identify encoded-words
The pattern =?charset?encoding?text?= is identified in the input string.
- 2
Decode using specified encoding
B encoding uses Base64 decoding, Q encoding uses Quoted-Printable decoding.
- 3
Return decoded text
The decoded text replaces the encoded-word in the original string.
FAQ
What is MIME encoding?
MIME encoded-word format is used in email headers to represent non-ASCII text. It uses the format =?charset?encoding?text?= where encoding is B (Base64) or Q (Quoted-Printable).
When would I need MIME decoding?
You need MIME decoding when you see encoded email subjects or From/To addresses that look like =?UTF-8?B?...?= or =?UTF-8?Q?...?=.
