Base64 decode

POST /api/base64-decode

Decode standard or URL-safe base64 to bytes. Whitespace and base64url variants are accepted; padding is optional.

Decodes a base64 string back to the original bytes. Handles: - Standard base64 (RFC 4648 §4, with `+` and `/`). - URL-safe base64 (RFC 4648 §5, with `-` and `_`). - Embedded whitespace and newlines (silently stripped). - Optional or missing padding (the `=` characters at the end). Use cases: decoding inline data URIs, decoding base64-encoded API payloads, recovering binary content from base64 logs.
