Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into a set of 64 printable ASCII characters. It is commonly used to embed binary data in text-based formats like JSON, XML, HTML and email.
Does this support Unicode and special characters?
Yes. This encoder handles full UTF-8 text including emojis, accented characters and non-Latin scripts.
Is Base64 encoding the same as encryption?
No. Base64 is an encoding scheme, not encryption. Anyone can decode a Base64 string. Do not use it to protect sensitive data — use proper encryption instead.
