Base64 Tool

About Base64

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 text.

Common Uses

• Embedding images in HTML/CSS/JavaScript
• Email attachments (MIME)
• Storing complex data in JSON
• Transferring binary data in web APIs
• Creating data URLs for small files

Benefits of Base64

• Ensures safe transport of data across environments that only support text
• Reduces HTTP requests when embedding images in web pages
• Avoids special character issues when transferring data
• Simplifies inclusion of binary data in plain text formats

Limitations

Base64 encoding increases the size of the data by approximately 33% (4/3 of the original size), so it is not efficient for large files or when bandwidth is a concern.
