Description
Convert text to Base64 format using different output options. Ideal for encoding data as plain text, data URIs, or HTML hyperlinks. For decode use Base64 Decoder.
How to Use
- Enter Your Text: Type or paste the text you want to encode into the editor.
- Choose Output Format: Select 'Plain text', 'Data URI', or 'HTML Hyperlink' to define how the encoded text should be formatted.
- Set Line Separator: Opt for 'LF (Unix)' or 'CRLF (Windows)' to specify how new lines should be handled.
- Multiple Entries Option: Toggle 'Multiple entries' if you want to encode each line of your input text separately.
More details
The TextEncoder interface accepts a sequence of code points as input and produces a stream of UTF-8 bytes as output.
