Base64 represents binary or text data using a restricted set of printable characters. It is an encoding format, not encryption, and should not be used to protect secrets.

WispData puts the interactive tool first and performs the calculation or transformation in your browser whenever possible. No account is required.

Frequently Asked Questions

Is Base64 encryption?

No. Base64 is reversible encoding and provides no confidentiality.

Does Base64 make data smaller?

Usually not. Base64 typically increases the size of the original data by roughly one third.

Is my text uploaded?

No. Encoding and decoding are performed in the browser.

Does WispData store what I enter?

No. This tool is designed to process the values you enter locally in your browser unless a page explicitly says otherwise.
