FAQ
Frequently Asked Questions
What is Base64 used for?
Base64 represents binary or text as ASCII so it can travel safely in JSON, emails, URLs and config files. Ercc encodes UTF-8 text correctly.
Does it support Chinese / emoji?
Yes. Encoding uses UTF-8 first, so Chinese characters and emoji are preserved and decode back exactly.
Is it private?
Yes — all encoding/decoding happens in your browser with no upload.
