## What it is
A pure-JavaScript Base64 encoder/decoder library supporting UTF-8 strings, Uint8Array, and URI-safe encoding. It works in browsers, Node.js, and as an ES6 module with a long-maintained, widely-used codebase.

## Use cases
- encode strings to base64 in javascript
- decode base64 to utf-8 text
- convert Uint8Array to base64
- url-safe base64 encoding
- base64 encode unicode strings
- replace btoa with utf8-safe base64

## When to choose
- you need consistent base64 encoding across browser and Node.js
- you must handle UTF-8/unicode strings safely
- you need URI-safe base64 or Uint8Array conversion

## When to avoid
- modern runtimes with btoa/atob or Buffer suffice
- you need general binary data encoding beyond base64

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: developer-tools, web-development, files
- platform: browser, cross-platform, bun
- tags: base64, encoding, decoding, utf8, uri-safe, pure-javascript, nodejs, deno
