How to keep the big picture of pdf

Hi there!
I have a pdf file, image size there 2481px width 3509 height in pdf.
I need to save images from pdf 1200px width for the site.
There is text, so it still needs to be able to take the text from the image.
How can I do and what program?
I tried to do it in coral, but maintaining defects appear.

you can using photoshop to catch it.

If you don’t have the original file that was used to create the PDF, you could use Acrobat to export the images. Or you could open the PDF in Illustrator and possible grab the text that way—depending on how it’s all been created.

Are you talking about text that is part of the image itself, or text from the PDF?
