What version are you using? This is not happening to me on 2015.4.
I am using InDesign 2015.4 and Acrobat Pro DC 2015.017.
When I export to an Interactive pdf I am using the default setting in Export Interactive PDF.
All the same for me, plus Mac OS. I set up a button to bleed off the page, and it was trimmed at the page edge with the default Interactive PDF export. Maybe someone else can shed light on this, but in the meantime, you can crop the PDF in Acrobat.
- View > Tools > Edit PDF
- Crop Pages on the top bar
- Draw an initial crop boundary, then double click to refine. Note that you can crop multiple pages in the lower right corner.
Why are you bleeding buttons off the page?
I am using the buttons as a slide show. I have 7 small thumbnail buttons on the left side of the page and when you click on each button one the corresponding large images that bleeds appears on the right side of the page.
It is happening for me as well.
This is from InDesign
Here is the interactive PDF
The answer, I suspect, is that the engineers at Adobe did not imagine that folks would put a bleed on a button when they redesigned the new improved Export to Interactive PDF. It does not have controls for Bleed and Slug as the Print PDF does.
You could file a feature request:
In the meantime, you will need to use a work-around, such as Barb suggested with cropping. You can crop all the pages at once in Acrobat, and it is non-destructive.
