Frequently Asked Questions
Common questions about this tool
Base64 converts binary data to text, making it safe to transmit over systems designed for text. Common uses include embedding images in HTML/CSS, encoding email attachments, and storing binary data in JSON.
No, Base64 is encoding, not encryption. It transforms data format but doesn't provide security. Anyone can decode Base64. For sensitive data, use proper encryption before Base64 encoding.
