Frequently Asked Questions
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data as ASCII characters. It is commonly used for embedding images in HTML/CSS, data URIs, and API authentication tokens.
Does it support non-ASCII text?
Yes — the tool uses UTF-8 encoding, so Chinese, Arabic, and other non-Latin characters are handled correctly.
