How to use the Base64 Encode tool?
- Copy your text to the clipboard first
- Paste into the text editing area
- Click the "Encode" button, the converted Base64 encoding will be displayed immediately below
- Click the "Copy" button, the converted Base64 code will be successfully copied to your clipboard
- Click the "Clear" button to quickly clear the text
What is the Base64 encoding format?
In computer programming, Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in sequences of 24 bits that can be represented by four 6-bit Base64 digits.
Common to all binary-to-text encoding schemes, Base64 is designed to carry data stored in binary formats across channels that only reliably support text content. Base64 is particularly prevalent on the World Wide Web where one of its uses is the ability to embed image files or other binary assets inside textual assets such as HTML and CSS files.
Base64 is also widely used for sending e-mail attachments. This is required because SMTP – in its original form – was designed to transport 7-bit ASCII characters only. This encoding causes an overhead of 33–37% (33% by the encoding itself; up to 4% more by the inserted line breaks).
Why do I need to convert the Text to Base64?
- Base64 is suitable for fast data transfer under HTTP and MIME protocols
- Only ASCII characters can be used in some systems, and Base64 can convert data of non-ASCII characters into ASCII characters
- After encoding the string, it is not easy to read, and has a certain encryption effect
