Can hide and print without background laters

Many pdfs these days have background layers which obscure the text.

This can hide and print un-selected layers, which is useful. It can't make an exception if the source pfg groups some mportant images with the background layers.

This, however, does not work with some scrolling tools, and translates attempts to scroll into zooming. I don't have the coordination to use Mac scrollbars, and rely on page up and page down in this app.

Developer Response ,

Hi Marja, we appreciate your comments and feedback. Could you please reach out to us at and provide us with more information on the "Scrolling tools" you use. We would like to look into this further so we can resolve the issue.

Just downloaded and was able to add text and save

This is what I;ve been looking for. A simple to use PDF annotator/editor for filling out form-like PDF docs. The only thing it's missing is the abilty to insert an image (jpg or gif) so I can paste in my scanned signature.
