![]() These six bits form a number corresponding to the index in the character set supported by the Base64 encoding scheme. These three bytes (24 bits) are further broken down into four packs of six bits each. Now the next question is, how Base64 encryption works?īytes formed the data, are broken down into 24 bits. ![]() As these 64 characters are present in almost all encoding schemes, so these are not controlled characters. Therefore, when you use Base64 encoding, there is less chance of data loss, and you are much certain that your data will reach the final destination without interruption. For example, when embedding an image into HTML, CSS file, or database.Ī Base64 encoded string looks like this aHR0cHM6Ly9pcGxvY2F0aW9uLmlvL2Jhc2U2NC10by1pbWFnZQ=īase64 encoding scheme uses the same 64 characters that are present in almost all encoding schemes. That encoding scheme transfers the binary data over the medium supporting textual data transfer, but not binary data transfer. There is another encoding scheme called Base 64 Encode.īase64 is a Binary to ASCII encoding scheme. Therefore, it will not be able to interpret the data correctly. Because application Y uses the encoding scheme, that is a subset of an application's A encoding scheme. Because if you involve application Y in the process, there is a high chance of data loss. If you have to send the data from application X to application Z, the best solution is to send it from X to Z directly. An application Z is using the same encoding scheme as application A.More specifically, using the ASCII encoding scheme, that can encode up to 128 characters. An application Y uses a B encoding scheme, a subset of the A encoding scheme.More specifically, using the UTF-8 encoding scheme, that can encode up to 2,164,864 characters. An application X is using A encoding scheme.Suppose you have three applications, X, Y, and Z. Other Base64 variations share the same property but they use different symbols in the last two values.Encoding is the process of converting a piece of information or instruction into a particular form. The Base64 implementation in MIME uses a-z, A-Z and 0-9 for the first 62 values. This mixture leaves the data impossible to be altered in transportation thru information systems, such as electronic mail, that were typically not 8-bit clean. The common concept is to select a set of 64 characters that is both part of a subset typical to most encodings. The specific set of characters chosen for the 64 characters needed for the base can vary among implementations. Base64 is generally used in a number of applications including electronic mail via MIME, and keeping complex information in XML. This guarantees that the data stays unchanged without modification during transfer. Types of URI charactersīase64 encoding schemes are generally used when there is a need to encode binary information that needs to be stored and transferred over media that are developed to deal with textual information. Basically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation. ![]() After you paste your encoded string and click the 'decode' button, you will see the decoded image and a button to download the image as a file. For instance, you can convert Base64 to PNG image. The term Base64 is coming from a certain MIME content transfer encoding. Base64 image decoder is a tool that converts Base64 string to image. Note: if you have large Base64 string (above 1mb) use the Base64 to file tool to upload the data as a file and decode it.Example: Enter the following encoded string 'YmFzZTY0IGRlY29kZXI=', hit the decode button and you will get 'base64 decoder' as output.The output will appear in a new field below the button.Input your Base64 encoded data into the input field.This tool is useful for debugging and testing the decoding process, as well as for gaining a better understanding of how Base64 decoding works. Our online Base64 decode tool helps you to convert encoded data that has been encoded using the Base64 encoding scheme into its original form. ![]()
