Frequently asked questions
What is Base64 used for?
Base64 encodes binary data as ASCII text. It is common in data URLs, JWT tokens, email attachments and API payloads.
Does this tool support Unicode?
Yes. Text is encoded with UTF-8 before Base64 conversion, so accented characters and emoji round-trip correctly.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it, so do not use it to protect secrets.
