I've used before PDF Expert by Readdle. But I really dislike seeing the gray spaces where the PDF ends and doesn't fit the entire screen. Now, I know that this is not "possible" per se, since PDF files are not meant to adapt to screen size, but I was wondering, is there any app for iPad with an option to "blur" that PDF ending and makes it seem like it fits the entire screen (even if it doesn't rearrange the content)?
I've looked everywhere on the AppStore, but haven't found anything similar to what I'm looking for. Any pointers would be appreciated, thanks.
EDIT: I'm aware that PDF Expert has a CROP option, that removes the PDF empty spaces to better fit the content on the screen, but in my experience it looks terrible because it zooms on the content.
