Base64 Encoder & Decoder
Encode UTF-8 text to standard or URL-safe Base64 and decode it locally.
Encode UTF-8 text or decode Base64 locally in your browser.
Standard Base64 uses +, /, and = padding. URL-safe Base64 uses - and _ without padding.
How to use this tool
Choose standard or URL-safe Base64 to match the receiving protocol, then test with non-sensitive UTF-8 text.
When not to use it
Base64 is encoding, not encryption; never use it to conceal a secret.
