Questions

Is Base64 encryption?

No. Base64 only changes how data is written; anyone can decode it. Never use it to hide passwords.

Is my data private?

Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.

Is it free?

Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
