Binary is Base2 - each character can be either a '0' or a '1'. BasesĬonsider binary, decimal, and hexadecimal numbers. There are standard ways to represent these larger alphabets using ASCII characters.
Other standards, like Unicode, exist to more fully represent all characters. Consider also times when you want to include characters from multiple languages in a single document. Extended ASCII encodings can add on support for characters of other languages, but 128 additional characters isn't enough to represent an alphabet in every language.Ĭonsider the number of variations in writing systems with heavy diacritic use, like Vietnamese's tonal marks or logographic characters in systems like Chinese or the number of Emojis available on your phone. The ASCII standard most easily supports English words and punctuation. The most prevalent system is called ' Latin-1'. There are several distinct encoding patterns for EASCII, so systems encoding or decoding characters to numbers need to agree on which numbers represent which characters. This extra room gives space for more characters, and is referred to as EASCII, or 'Extended ASCII'
NET DECODE BASE64 HOW TO
Any system that uses this standard knows how to make this translation, and so these characters can be encoded to numeric representations and processed by computers, and shared between systems that all understand this way of representing supported characters.īecause computers today typically work in multiples of 8 bits at a time, there is room for 256 characters. For example, 'A' is always '65', and 'h' is always '150'.
This means that each of these supported characters can also be represented as a number. The URI is of the format data:$ is the Base64 encoded contents of the file you're embedding.ĪSCII is a standard for representing 128 different characters: capital and lowercase letters, numbers, common punctuation, spaces, and some control instructions used by computers to understand documents. This can be useful for removing dependencies on external files, to reduce the number of network requests or to allow a document to exist on its own. Use For Web Developmentīase64-encoded copies of images, CSS, fonts, and JavaScript can be used in places where you would otherwise reference a URL.
NET DECODE BASE64 PORTABLE
Encoded URI components will be decoded.īase64 encoding is a convenient, portable way of representing data. URL shortcuts: You can link to this site to encode or decode a specific input, like world or.Auto-detection: Just paste! If your input looks like it's Base64-encoded already it will be decoded, otherwise it'll be encoded.Drag and Drop: Drag a file to quickly convert it.
