How to use Base64 Encode Decode

Paste the plain text or Base64 value you want to inspect into the input field.
Choose encode when you need a text-safe representation, or decode when you need to read the original content.
Review the output carefully before using it in an API, email template, token sample, or embedded data URI.

Example workflow

If an API response contains a Base64-looking string, you can decode it immediately to confirm whether it is plain text, JSON, or an expected data fragment before debugging deeper.

Privacy note

Encoding and decoding happen in the browser, which is useful when you want to inspect small values without sending them to a server.
