Hi Everyone,

To reduce the total file size of my HTML outputs (which have to be downloaded over 2G networks in the developing world) I am exploring the use of the WebP image file format. Everything is working well for the HTML output, but the images are not being processed by DITA-OT when building PDFs. 

I can print an HTML file to PDF and the images show up, so the problem is not a constraint of the PDF format. Does anyone know whether DITA-OT can support (or be made to support) WebP images for PDF outputs?

Hi Mark,
I have not experienced to use WebP format until now. But AH Formatter do supports this format:

If it is not usable in your DITA-OT, it may be the problem of DITA-OT itself.
