Listed here are a few examples on how to embed Base64 resources within different web documents.ĭata:image/jpeg base64,/9j/4AAQSkZJRgABAQEAWgBaAAD/4gxYSUNDX1BST0ZJTEUAAQEAAAxITGlubwIQAAB.īackground-image: url('data:image/jpeg base64,/9j/4AAQSkZJRgABAQEAWgBaAAD/4gxYSUNDX1BST0ZJTEUAAQEAAAxITGlubwIQAAB. How can I embed Base64 encoded resource directly into HTML, XML and CSS files? Solution 1 escaping the string before encoding it Solution 2 rewrite the DOMs atob()and btoa()using JavaScript's TypedArrays and UTF-8 Base64is a group of similar binary-to-text encodingschemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. Just paste your textual data in the form below, press the Base64 Encode button. Encode each line separately (useful for when you have multiple entries). This means that the Base64 version of a string or file will be at least 133 the size of its source (a 33 increase). So, three 8-bits bytes of the input string/binary file (3×8 bits 24 bits) can be represented by four 6-bit Base64 digits (4×6 24 bits). Mainly used in email to transfer 8-bit data over a 7-bit data path.
To encode binaries (like images, documents, etc.) use the file upload form a little further down on this page. Encoded size increase Each Base64 digit represents exactly 6 bits of data. Base64 is an encoding method that uses 7-bit printable ASCII characters. If the number of bytes are not in numbers of three, then padding is used = for 1 byte and = for 2 bytes.Ĭonsult wikipedia for more information. Worlds simplest online base64 encoder for web developers and programmers. Encode to Base64 format Simply enter your data then push the encode button. Those 6 bits form a number corresponding to the index in the character set supported by Base64 (A-Z, a-z, 0-9, + and /). Worlds simplest online base64 encoder for web developers and programmers. Use this free tool to turn binary data into text (encode) or text into binary (decode). The resulting buffer of 3 bytes is then broken in 4 packs of 6 bits each.
How does Base64 encoding work?īytes forming the data are broken into buffers of 24 bits (3 bytes at a time). Concrete examples would be sending images in an XML file or in an email attachment. This is useful when binary data needs to be sent over media that are usually designed to handle textual data. Message Digester (MD5, SHA-256, SHA-512)īase64 is an encoding scheme used to represent binary data in an ASCII format.
