Base64 Encode/Decode FAQ
How do I decode a Base64 string?
Paste the Base64 string into the input box and click Decode from Base64. The original text appears on the right. If the string is not valid Base64, you will see an error.
What is Base64 used for?
Base64 encodes binary or text data into a plain text format that is safe to send in places that only handle text, like inside JSON, data URLs, email attachments, or API tokens.
Does it support emoji and other languages?
Yes. Craftora uses full UTF-8 encoding, so emoji, accented characters, and non-Latin scripts encode and decode correctly.
Is my data safe?
Yes. Encoding and decoding run entirely in your browser on your own device. Your text is never sent to any server.
Do I need to sign up?
No. The Base64 tool is free with no account and no limits.
