text → Base64
This tool encodes plain text into Base64, a text-safe encoding scheme commonly used to embed binary-like data in places that only accept plain text, such as JSON fields, URLs, or email attachments.
Encoding a string to safely include in a URL, config file, or API payload.
Preparing a small piece of data to embed inline in HTML or CSS as a data URI.
Encoding credentials or tokens for use in a Basic Auth header during development.

Yes, typically by around 33%, since it represents binary data using a limited set of readable characters.
