RFC - The Base16, Base32, and Base64 Data Encodings
Use the super simple online form below to decode or encode your data. Other tools Encode to Base64 format Simply use the form below To encode binaries like images, documents, etc.
Split lines into 76 character wide chunks useful for MIME. Live mode OFF Base64 pdf html in real-time when you type or paste supports only unicode charsets.
Encode files into Base64 format Click base64 pdf html tap here to select a file to encode You have to select exactly one file to encode maximum MB in size. Newline separator for split lines into chunks.
Please note that the encoded file is removed from our system right after the first download attempt or 15 minutes of inactivity.

Base64 encode your data in a hassle-free way, or decode it base64 pdf html human-readable format. Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data.
Interpretation of non-alphabet characters in encoded data Base encodings use a specific, reduced, alphabet to encode binary data. Non alphabet characters could exist within base encoded base64 pdf html, caused by data corruption or by design. Non alphabet characters may be exploited as a "covert channel", where non-protocol data can be sent for nefarious purposes.
Non alphabet characters might also be sent in order to exploit implementation errors leading to, e.
Implementations MUST reject the encoding if it contains characters outside the base alphabet when interpreting base encoded data, unless the specification referring to this document explicitly states otherwise.
Such specifications may, as MIME does, instead state that characters outside the base encoding alphabet base64 pdf html simply be ignored when interpreting data "be liberal in what you accept".

Note that this means that any CRLF constitute "non alphabet characters" and are ignored. If more than the allowed number of pad characters are found at the end of the string, e.
Choosing the base64 pdf html Different applications have different requirements on the characters in the alphabet.
Here are a few requirements that determine which alphabet should be used: Characters "0", base64 pdf html are easily interchanged, as well "1", "l" and "I". In the base32 alphabet below, where 0 base64 pdf html and 1 one is not present, a decoder may interpret 0 as O, and 1 as I or L depending on case.
However, by default it should not, see previous section. For base 16 and base 32, this determines the use of upper- or lowercase alphabets. There is no universally accepted alphabet that fulfills all the requirements. Base64 pdf html this document, we document and name some currently used alphabets.
Base 64 Encoding The following description of base 64 is due to [ 2 base64 pdf html, [ 3 ], [ 4 ] and [ 5 ].

The Base 64 encoding is designed to represent arbitrary sequences of octets in a form that requires case sensitivity but need not be humanly readable. The encoding process represents bit groups of input bits as output strings of 4 encoded characters.
Proceeding from left to right, a bit input group is formed by concatenating 3 8-bit input groups. These 24 bits are then treated as 4 concatenated 6-bit groups, each of which is translated into a single digit in the base 64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable characters. Base64 pdf html character referenced by the index is placed in the output string. A full encoding quantum is always completed at the end of a quantity. When fewer than 24 input bits are available in an input group, base64 pdf html bits are added on the right to form an integral number of 6-bit groups.
