Tips & Best Practices

  • Base64 encoding is commonly used for encoding binary data in text format.
  • Useful for embedding images in HTML/CSS, encoding email attachments, and API data transfer.
  • Base64 strings are about 33% larger than the original text.
  • The 'Swap' button quickly switches between encode and decode modes.
  • Base64 encoding is not encryption - it's encoding and can be easily decoded.

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 to encode data that needs to be stored and transferred over media that are designed to deal with textual data. This ensures that the data remains intact without modification during transport.

When to Use Base64?

Base64 is often used in web development for embedding image data directly into HTML or CSS files, encoding email attachments, and transmitting complex data structures via URLs. It allows binary data (like images or files) to be handled as simple text.

Secure and Private

Our Base64 Encoder/Decoder works entirely within your browser. The data you encode or decode is processed locally and is never sent to our servers. This ensures your sensitive information remains private and secure.

Frequently Asked Questions

No, Base64 is an encoding scheme, not encryption. It is not designed to keep data secret but rather to ensure data integrity when transmitted. Anyone can decode a Base64 string back to its original form.
