Base64 to Image Converter - Encode and decode images

What is Base64 Image Encoding?

Base64 is an encoding scheme that converts binary data (like images) into ASCII text. This allows images to be embedded directly in text-based formats like HTML, CSS, JSON, or XML without needing separate image files.

Common use cases for Base64 images:

  • Embed in HTML/CSS - Include small images directly in stylesheets or HTML
  • API responses - Send images as part of JSON payloads
  • Email templates - Embed images that display without external requests
  • Database storage - Store images as text in databases

  2. Upload your image - Drag and drop or click to upload PNG, JPG, GIF, WebP, or SVG
  3. Copy the result - The Base64 string is generated instantly with data URI prefix
  4. Use in your code - Paste directly into HTML img src, CSS url(), or JSON
