Encode text or a file to a base64 string. Base64 Encoding - Go by Example Go supports both standard and URL-compatible base64. But what i really think you wanna do is to turn a base64 into a blob (binary container) and then upload it to a api as binary (not as base64) if that is true then this is just a duplicate of Creating a Blob from a base64 string in JavaScript and then it's just a mather of sending it with ajax to a server. This is to ensure that the data remains intact without modification during transport. Here is a short introduction of this new API (apparently it has a little more than the regular encode/decode API). Converting between Blobs and ArrayBuffers ; Creating a TypedArray from a Base64 string. BSON’s binary structure encodes type and length information, which allows it to be parsed much more quickly. You need to encode this data into a string so that it can be sent over a binary-unfriendly transport such as email. Many programming languages, such as PHP and Javascript, include Base64 encoding and decoding functions in order to interpret data.
