Flatten PDFs on app on iPad troubles

I use fillable templates on my ipad while out on sites with customers. I want to then email them this pdf, but remove all of the fillable boxes. I get complaints when they are sent this way that they can't read what I wrote in the boxes, and I also don't want them to be able to edit my document. I've seen the terms I want to change from a fillable pdf to a flat pdf. I can do this on my desktop. However, when I am remote I can not find a way to do that through the Adobe Acrobat Reader App that I have on my iPad. Anyone have any insight to this?
