Is Base64 encryption?

No. Base64 is a reversible encoding, not encryption — anyone can decode it back to the original text. Use it for compatibility, not for hiding sensitive data.

Is my text sent to a server?

No. Encoding runs entirely in your browser, so your text stays private.

When do I need Base64 encoding?

Common cases include embedding binary data in JSON, building data URIs for images, and passing values through systems that only accept plain text.

About Base64 Encode

Encode strings to Base64 for development, testing, and data embedding. Base64 is widely used to safely pass binary or special-character data through text-only systems like JSON, URLs, and email headers.
