SGVsbG8sIHdvcmxkIQ==Hello, world!Frequently asked questions.
Is Base64 encryption?
No. Base64 is an encoding, not encryption. It is fully reversible and provides no confidentiality.
Does it support UTF-8?
Yes. Text is encoded as UTF-8 bytes before base64 conversion, so emoji and accented characters work correctly.
Is my data uploaded?
No. Encoding and decoding happen entirely in your browser.
