Base64 Converter

Base64 encoding converts text or binary data into a portable ASCII string that can be placed in JSON, XML, HTML, CSS, email, and API payloads. The reverse operation decodes a Base64 string back to its original readable value. Base64 is an encoding format rather than encryption, so it must not be used to hide passwords or confidential information.

Use the online Base64 converter to encode Unicode text, including Cyrillic and accented characters, or decode an existing value without installing additional software. The result can be copied immediately, which is useful when debugging integrations, preparing data URIs, checking tokens, or transferring content through systems that accept text only.
