    It would be helpful if this handy tool would also show the before/after size of the image, in bytes, perhaps also with "% size increase"
    • Administrator,
      Hello! Thank you for your idea. Are you sure this is useful given that the output size is always 33% larger than input?

      Hello Rajesh,
      There is no magic. It just downloads the file from remote server and encodes it to Base64.

  • Adam,
    Could you add a "Download Base64 Encoded file of URL" (or something similar) button that directly downloads a "<filename.ext>.b64" file without having to write it into the Base64 result UI textbox?

    [UPDATED: ]
    Sometimes for large files, the result box takes a long time to get populated, and is truncated.
