The Base64 Image Viewer is an online program that allows users to decode and display photos encoded with the Base64 technique. These characters are then mapped back to their 8-bit binary representations, and the resulting binary data is the decoded form of the original input. These 24 bits are then split into four groups of 6 bits, which correspond to specific characters in the Base64 character set. The encoded data is divided into groups of four characters, each representing 24 bits. How Does Base64 Decoding Work?īase64 decoding works by taking a Base64-encoded string and converting it back to its original binary representation. The resulting decoded data can then be used in its original form, such as an image or file. This involves reversing the encoding algorithm, which maps each group of 6 bits in the Base64 encoded data to a corresponding 8-bit byte in the original binary data. What is Base64 Decoding?īase64 decoding is the process of converting data encoded in Base64 back to its original binary format. It is commonly used for encoding binary data, such as images or files, into a format that can be easily transmitted over text-based channels like email or HTML. Yu can easily turn off this feature by enabling the “Strict Decoding” option.Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format by converting it into a set of 64 characters, consisting of letters, numbers, and symbols. 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. Enable the strict decoding mode if you want to make sure that your Base64 string contains only valid characters.Select the algorithm standard (if you do not know, leave it as it is, as the decoder will automatically detect it).Paste your string in the “Base64” field.How to decode Base64 online using this decoder tool Guru A virtual teacher who reveals to you the great secrets of Base64
