What is a Base64 to image converter?

A Base64 to image converter decodes an image payload back into a previewable and downloadable file. It supports full data:image/...;base64,... URLs and raw Base64 strings.

How to use it

  1. Paste a Base64 image string or data URL.
  2. Use auto-detect for common image formats, or choose the MIME type manually.
  3. Preview and download the decoded image.

Example

Input: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA...

Output: a downloadable PNG image.

Common mistakes

  • Raw Base64 does not tell the browser the image type.
  • SVG may need the SVG option if auto-detection cannot identify it.
  • Huge Base64 images are slower and larger than normal image files.
