What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data (like images) as a string of ASCII characters. This allows you to embed images directly into HTML, CSS, or JavaScript without needing a separate image file or hosting.

Common Uses

  • Embed small icons and logos directly in HTML to avoid extra HTTP requests
  • Store images in JSON APIs or databases as strings
  • Send images in emails or over APIs that only support text
  • CSS background images embedded directly in stylesheets

📖 How to Use

  1. Drag & drop your image or click to select
  2. Choose an output format
  3. Copy the Base64 output
  4. Paste it into your HTML, CSS, or JSON

💡 Tip

Base64 encoding increases file size by ~33%. It's best for small images (icons, logos) under 10KB. For large images, use a standard URL reference instead.
