Tips

  • To convert your own image instead, click Choose Files... in the empty workbench.

  • Keep Raw Base64 selected when your destination expects only Base64-encoded image data, without a data URI prefix.

  • Watch outBase64 is an encoding, not encryption. It does not conceal or protect confidential image content.
