What this does

Encodes an image file as a Base64 text string, ready to drop into HTML (<img src="data:image/png;base64,…">), CSS or JSON. The image then travels inside the file instead of as a separate request.

When to use it

  • Tiny icons and logos in an email template or a single-file HTML page.
  • Embedding an image in a JSON API response.
  • Avoiding an extra HTTP request for a very small asset.

Good to know

Base64 is about 33% larger than the binary file and cannot be cached separately. Keep it for images under roughly 10 KB.

Enjoy the little things in life. For one day, you may look back and realize they were the big things. Many of life's failures are people who did not realize how close they were to success when they gave up.
