Does Base64 encoding make data secure?

No. Base64 is trivially reversible by anyone and is not encryption. Never use it to hide passwords or personal data.

Why do non-Latin characters break?

In UTF-8 a single non-Latin character spans several bytes. Implementations that work per character rather than per byte corrupt them, so this tool converts to UTF-8 bytes before encoding.

When to use Base64

Base64 represents arbitrary binary data using 64 safe ASCII characters. It is a transport encoding rather than encryption, which is why it is used to carry images or files through text-only channels such as JSON fields, email attachments, data URIs and HTTP headers.

How to use it

Paste the text or Base64 string into the input box.
Choose the encode or decode direction.
Copy the result.
