## When this is useful

Base64 represents bytes using a limited text alphabet, which is useful when a channel expects printable text. It is often seen in small data payloads and protocol examples. Encoding increases the size and provides no confidentiality: anyone with the value can decode it.

## A reliable workflow

The encoder converts your text to UTF-8 bytes before Base64 encoding, allowing accented characters and non-Latin text to round-trip. Decode expects standard Base64 representing valid UTF-8. Binary file contents or URL-safe Base64 variants may require a different workflow.

Example input: Hello, دنیا

## What to check before you finish

Check the decoded text against the source, including line endings. Never treat an encoded API key as protected. If a value contains a password, avoid copying it on shared computers, because clipboard managers can retain it after the page closes.

## Keep the next step simple
