Encode text as Base64 or inspect a Base64 string as decoded text.
The Base64 Encoder and Decoder converts between text and Base64 strings. Use the paired fields to inspect encoded text from an API payload or prepare a text value for a system that expects Base64.
The interface does not show a file upload, download button, swap button, or URL-safe alphabet toggle. Do not use it as a binary-file converter without checking that the result suits your file workflow.
Standard Base64 uses +, /, and = for padding. URL-safe Base64 uses - and _ in place of the first two characters. Padding requirements depend on the receiving format; some formats omit it. Check the variant your application expects rather than assuming the two are interchangeable.
Base64 does not protect a secret. Anyone who has the encoded value can decode it. For non-ASCII text, confirm that the character encoding matches the application that will read the value. A decoded binary payload may not be readable text.

Enter your source text in Text to encode (decoded), then inspect the corresponding Base64 value.
Enter Base64 in Base64 string to decode (encoded), then check the decoded text and expected character encoding.
