Frequently Asked Questions

QWhat is Base64 encoding?

Base64 is an encoding scheme that converts binary or text data into a set of 64 ASCII characters. It's commonly used for embedding data in URLs, HTML, CSS, email, and JWT tokens.

QIs Base64 the same as encryption?

No. Base64 is encoding, not encryption. It can be decoded by anyone without a key. Never use it to protect sensitive or confidential data.

QDoes it support Unicode and emojis?

Yes, this encoder handles the full Unicode range including emojis, CJK characters, Arabic, and all other non-Latin scripts.

QWhere is Base64 commonly used?

Base64 is used in data URLs (images in CSS/HTML), JWT tokens, SMTP email attachments, HTTP Basic Authentication headers, and storing binary data in JSON.

QWhat is the size overhead of Base64?

Base64 encoding increases data size by approximately 33%, since every 3 bytes of input becomes 4 ASCII characters.
