Text encoding

Base64 represents binary data as text. This tool handles UTF-8 text so emoji, accented characters, and non-Latin scripts can be encoded and decoded safely.

URL-safe Base64

URL-safe mode replaces characters that often need escaping in URLs. Use it for tokens, identifiers, or payloads that must travel through query strings or path segments.
