Base64 Encoder

What is Base64 Encoding?

Base64 converts any data into a text format using only 64 safe ASCII characters. This makes it possible to include binary data in places that only support text, like HTML, JSON, or email.

Common Applications

• Data URIs: Embed small images directly in HTML or CSS
• API Authentication: HTTP Basic Auth uses Base64 credentials
• Data Transfer: Send binary files through text-only channels
• Storage: Store binary data in text-based databases

How to Use

Enter any text and get the Base64 encoded version instantly. The output is safe to use in URLs, HTML attributes, and most programming contexts.

Size Consideration

Base64 encoding increases size by about 33%. This is the tradeoff for compatibility with text-only systems.
