What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data.

Common Use Cases:

  • Embedding Images: Convert small icons into strings to include directly in HTML/CSS.
  • Data URIs: Sending complex data through URL parameters securely.
  • Authorization Headers: Used in Basic Auth to transmit credentials.
  • Email Attachments: Converting binary files for MIME protocol compatibility.

Frequently Asked Questions

Is Base64 a form of encryption?

No. Base64 is an encoding format, not encryption. It can be easily reversed by anyone without a key.

Does it support non-English characters?

Yes, our tool uses a UTF-8 compatible approach to ensure Hindi, Emojis, and other characters are encoded correctly.

Why does the size increase after encoding?

Base64 encoding increases the data size by approximately 33% because it represents 3 bytes of data using 4 characters.
