About This Tool

The Image to Base64 Converter allows you to transform image files into Base64-encoded text. This is commonly used in web development to embed images directly inside HTML, CSS, or JSON responses.

What Is Base64?

Base64 is a binary-to-text encoding scheme that represents image data using ASCII characters. It enables images to be transmitted safely over text-based formats without corruption.

How It Works

  • Upload or drag an image into the tool
  • The image is read locally in your browser
  • It is converted into a Base64 data string
  • You can download the result as a .txt file

Best Practices & Advice

  • Use Base64 for small images (icons, logos)
  • Avoid Base64 for large images—it increases file size
  • Ideal for emails, inline CSS, and API payloads

FAQs
