FAQ
Frequently asked questions
What is Base64 used for?
Base64 turns binary data or text into plain ASCII characters, so it can travel safely in JSON, HTML, email and URLs — for example data: URIs, API tokens and email attachments.
Is Base64 encryption?
No. Base64 is an encoding, not encryption — anyone can decode it. Never use it to hide passwords or secrets.
Does it support emoji and non-English text?
Yes. Text is converted to UTF-8 before encoding, so accents, Hindi, Chinese and emoji all round-trip correctly.
