Export antialiased images

We regularly export large presentations from PDFs into image sequences for further processing. The slides are composed of text, photos and graphics. Acrobat DC can export pages into separate images, but does not give option to antialias them. This results in jagged typography at any screen-friendly resolution. Exporting the slides in higher resolution than neccessary and then shrinking them with Photoshop adds unneccessary steps and disk space requirements to workflow. So why not offer antialiasing option for export straight from Acrobat Pro?
