Questions people ask
What is Base64 used for?
Base64 turns binary or text data into plain ASCII text so it can travel safely in JSON, URLs, or emails. It is encoding, not encryption — anyone can decode it.
Does it handle Unicode and emoji?
Yes — the tool uses UTF-8 aware encoding, so emoji and non-Latin scripts round-trip correctly.
Is my data sent anywhere?
No. Everything runs locally in your browser. Nothing is uploaded or stored.
