Frequently asked questions
Can this decode invalid Base64?
No. Invalid Base64 input shows a readable error instead of producing unreliable output.
Does this work with Unicode text?
Yes. The encoder and decoder handle regular Unicode text in the browser.
Is Base64 encryption?
No. Base64 is an encoding format, not encryption, and should not be used to protect secrets.
