How to use Image to Base64 Data URI

data:<mime>;base64,… of the exact file bytes — no re-encoding.

  1. Prepare your input

    Choose an image.

  2. Use the workspace

    Generate a data URI from its original bytes.

  3. Check your result

    Test the result where you intend to embed it.

Know the limits

Base64 increases text size and does not compress the image; some applications reject large inline data.
