FAQ

What is Base64?

Base64 is a way of representing binary or text data using 64 safe ASCII characters. It's used to embed data in URLs, JSON, emails and data URIs where raw bytes would break.

Is Base64 encryption?

No. Base64 is encoding, not encryption — anyone can decode it. It hides nothing; it just makes data transport-safe.

Is my text uploaded anywhere?

No. Encoding and decoding happen entirely in your browser, so your text never leaves your device.
