What is Base64 encoding?

Base64 is an encoding scheme that converts binary data into ASCII text format. It uses 64 characters (A-Z, a-z, 0-9, +, and /) to represent binary data as text. It's commonly used to encode data for transmission over text-based protocols like email or HTTP.

Is Base64 encoding secure?

Base64 is not encryption — it's merely encoding and can be decoded easily. Do not use it to secure sensitive data like passwords. For security, use proper encryption methods instead.

Is my data sent to any server?

No. All encoding and decoding happens locally in your browser using JavaScript. Your data is never sent to any server.

What can I use Base64 encoding for?

Common uses include: encoding binary data (images, files) for text storage or transmission, URL-safe encoding of special characters, encoding credentials for API authentication, and simple data encoding for web development.
