Frequently Asked Questions
What is Base64?
Base64 is an encoding scheme that converts binary data into ASCII text. It is widely used for embedding images, files, or data in JSON, HTML, and email.
Does Base64 encryption secure my data?
No. Base64 is encoding, not encryption. Anyone can decode it. Do not use it to hide sensitive information.
Does this handle Unicode and emoji?
Yes. The encoder uses TextEncoder (UTF-8) before Base64 encoding, so all Unicode characters including emoji are handled correctly.
