What is Base64 image encoding?

Base64 encoding converts binary image data into a string of ASCII characters, making it safe to embed in text-based formats like HTML, CSS, or JSON. A base64-encoded image can be used directly as an img src via a data URI: data:image/png;base64,…

Accepted input formats

  • Raw base64 — just the base64 string with no prefix (the tool auto-detects the image format)
  • Data URI — full data:image/…;base64,… string
  • HTML img tag — paste an entire <img src="data:image/…;base64,…"> tag and the base64 is extracted automatically

Supported image types: PNG, JPEG, GIF, WebP, BMP, SVG, and more — any format your browser can display.
