Page is larger than what is shown

[Fico5C6C]

So I downloaded a PDF of an old article that has on every page bottom cropped out. What is weird is that Adobe detects the whole page, and when I export a selection as PNG I get a full page.

I tried to go Export as PDF for the whole document, but it exports in the same view that this "damaged" PDF has.

Is there any way for me to export whole pages for the whole document (or edit PDF to see them without exporting as an image) without going page-by-page?

NB: This is not an Adobe problem, but a PDF problem for sure - I opened document in other PDF-viewing programs I have and there is the same problem in all of them.

Someone cropped the pages,  normal process that doesn't crop the contents. Acrobat can change the crop back.

But how is my question? 

[Test Screen Name]

In Acrobat Pro DC, go to Edit, and Crop is one of the options in the toolbar.

I know where the crop is, and how to use the crop. What I'm asking is how to revert crop to get full page again. All settings I tried yielded no result.

Ok, you might have mentioned that and we'd have saved you time. There is no guaranteed recipe to get the crop you want, you may need to experiment with the numbers. However, here's the first step

- Go to Edit PDF

- Clip Crop

- Drag out a box, any size and press RETURN

- The crop choices now appear

- For the first try, use SET TO ZERO

- Select ALL PAGES

WARNING: Work with a copy, be sure to keep the original

Nothing changed, tried to change values, still nothing sadly.

If changing values has no effect, then it isn't cropping that made the page smaller, sadly. Cropping is the only tool we have.

In addition to the good information above, go to Tools> Print Production> Set page boxes, click the button Set to zero (applied to the crop box, all pages), If that doesn't work, go to Tools> Print Production> Preflight> Fixups (blue wrench icon)> Set CropBox to TrimBox (Fix), if that doesn't work, my last suggestion is to try and place the PDF into a new InDesign document, using the bounding box option when placing the PDF, then export to a new PDF.

Still doesn't work, but I think I found something that could help with troubleshooting. 

It seems like the author did not crop the whole page but actually cropped the image on-page. So no matter what margin I set I always get the same result because it is not a page that is cropped, but the image on the page.

When I go to "Remove crop" I can move images and see parts that are cropped out. Is there any way I can remove crop for all images in the whole document and resize the page to fit the new height of images correctly, or will I need to manually export all images?

I don't think Acrobat is able to change the cropping on an image (as opposed to cropping on a page). You are left with what the designer intended. It's sheer luck that you have the original uncropped images, often the cropped part is removed when the PDF is made.

In the Set Page Boxes dialog at the bottom of the panel there is an option to increase the page size, try that.

If that doesn't work, you can go to Tools> Export PDF> Image> Export all images, this should extract all of the images from all pages, hopefully not cropped.
