Frequently Asked Questions
What is Base64 used for?
Base64 encodes binary or text data into a safe ASCII format, commonly used for data URIs, email attachments, and passing data in URLs.
Does it support emoji and non-English text?
Yes. The tool converts to and from UTF-8 first, so Unicode characters are handled correctly.
Is my data uploaded?
No. Encode and decode happen locally in your browser using native functions. Nothing leaves your device.
