Hi
Thanks for your request. Do you mean storing images as base 64 in HTML produced by Aspose.Words? if so you can achieve this by setting the option in HtmlSaveOptions:

Hope this helps.
Best regards,
Thank you for additional information. Aspose.Words does not work with stand alone images. Of course, you can insert your image into a Document and save the document to HTML and then extract base64 representation of the image from this HTML. However, I suppose you can use the approach like suggested will be better:
