File to Base64
Select a file to convert to base64 or read as base64.
When you have some binary data that you want to ship across a network, you generally don't do it by just streaming the bits and bytes. Because some media are made for streaming text. You never know -- some protocols may interpret your binary data as control characters (like a modem), or your binary data could be screwed up.
So to get around this, people encode the binary data into characters. Base64 is one of these types of encodings.
