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 encode data for transmission over media designed to handle text, such as email or JSON.
Is Base64 encryption?
No! Base64 is encoding, not encryption. It provides no security. Anyone can decode Base64 — it's meant for data formatting, not protection.
When should I use Base64?
Common uses include: embedding images in HTML/CSS (data URLs), sending binary data in JSON APIs, encoding email attachments (MIME), and storing complex data in cookies.
