What Base64 does
Base64 represents bytes using printable ASCII characters. Text is converted to UTF-8 before encoding, so non-Latin characters and emoji work correctly.
Where Base64 is used
Base64 appears in data URLs, MIME messages, API payloads, and text configuration. It is encoding, not encryption.
Local processing
Text is encoded and decoded on your device and is never sent to the server.
Frequently asked questions
Does Base64 protect secret data?
No. Base64 is easily reversible and provides no confidentiality.
Does it support Unicode text?
Yes. The tool explicitly uses UTF-8 before and after Base64 conversion.
