![]() In mathematics, the base of a number system refers to how many different characters represent numbers. What is Base64 Encoding?īase64 encoding is a type of conversion of bytes into ASCII characters. We will then use Python to Base64 encode and decode both text and binary data. In this tutorial, we would learn how Base64 encoding and decoding works, and how it can be used. By encoding our data, we improve the chances of it being processed correctly by various systems. Files with binary data, bytes that represent non-text information like images, can be easily corrupted when being transferred and processed to text-only systems.īase64 encoding allows us to convert bytes containing binary or text data to ASCII characters. Yu can easily turn off this feature by enabling the “Strict Decoding” option.Have you ever received a PDF or an image file from someone via email, only to see strange characters when you open it? This can happen if your email server was only designed to handle text data. For example, this avoids errors if the Base64 string was copied with extra spaces or punctuation marks. ![]() Moreover, it can decode strings encoded using the following character encodings: xsd:Name (provides safe strings to be used as valid XML Identifiers)Ĭharacter encodings supported by Base64 decoder.xsd:NMTOKEN (provides safe strings to be used as valid XML Name Tokens).PEM (a deprecated standard originally used by the Privacy-Enhanced Mail protocol).IMAP (used by Internet Message Access Protocol as mailbox international naming convention).Base64URL (unlike other standards, the output of this standard can be safely used as a filename or URL).ASCII Armor (used by OpenPGP, is identical to the Base64 for MIME, but appends a checksum of input).MIME (the output is splitted into fixed 76 line-length and is used to encode email content, such as files, or non-latin letters).Main (used by default by everyone and everywhere).To claim the title of “best Base64 decoder”, it supports the following standards: Standards accepted by online Base64 decode tool Download or copy the result from the “Text” field.If you know what encoding the original data was in, select it in the “Character Encoding” list. ![]()
