Comment utiliser

Decoding Base64 images

Paste a data URL that starts with data:image/ or a raw Base64 string. The tool detects the format from the decoded bytes and shows a preview.

  1. Paste the Base64 string or data URL.
  2. Check the preview.
  3. Download the image if needed.

Questions fréquentes

How do I know the image type?

The converter checks the magic bytes of the decoded data, so a raw Base64 string is detected without a data URL prefix.

Why does the preview fail?

The string is not valid Base64 image data. Check that no characters were lost when copying.
