Frequently asked questions

Is text uploaded?

No. Every encode and decode operation runs locally in your browser.

Which formats are supported?

Base64, URL component, HTML entities, JSON string escapes, hex bytes, and binary bytes are supported.

Can it handle Unicode text?

Yes. Base64, hex, and binary use UTF-8 so emoji and non-Latin text round-trip correctly.
