Frequently Asked Questions
What is Base64 encoding?▼
Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It's commonly used to embed images in HTML/CSS, encode email attachments, and transmit data in URLs.
Is Base64 encryption?▼
No — Base64 is encoding, not encryption. It does not provide security. Anyone can decode Base64 data. Use proper encryption (AES, RSA) for sensitive data.
