About Base64 Encoding

About Base64 Encoding

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

This encoding helps to ensure that the data remains intact without modification during transport. Base64 is used commonly in a number of applications including email via MIME, storing complex data in XML or JSON, and encoding credentials in HTTP Basic authentication.

Our Base64 encoder and decoder tool supports standard Base64, URL-safe Base64, and MIME encoding formats, making it versatile for various development needs.

How to Use

  1. Encoding: Enter text in the input field or upload a file, then click "Encode to Base64" to convert it to Base64 format.
  2. Decoding: Paste a Base64 string in the input field or upload a Base64 file, then click "Decode from Base64" to convert it back to original text.
  3. File Support: Upload files for encoding or download decoded files when working with binary data.
  4. Format Options: Choose between standard, URL-safe, or MIME encoding formats based on your requirements.
  5. Copy Results: Use the copy buttons to quickly copy encoded or decoded results to your clipboard.
  6. Quick Actions: Use sample data to test the tool or clear inputs with single click.

Pro Tip: Use URL-safe Base64 when encoding data for URLs to avoid issues with special characters.
