Base64 provides no confidentiality.
Frequently asked questions
Can I encode Korean or other Unicode text?
Yes. Text is encoded as UTF-8 bytes first. Decoded bytes must also be valid UTF-8 text. Choose Base64URL for URL-oriented values; use encryption when confidentiality is needed.
Is my file or input sent to a server?
No. Processing stays in your current browser session.
