Usually only slightly. Cropping changes the visible page area (the CropBox), but the underlying text and images outside the crop are still stored in the file. If your goal is a smaller file, crop first and then run the result through our Compress PDF tool for a meaningful size reduction.
You crop by dragging the box to the exact area you want to keep, so you can trim a page down to a target proportion by eye. Apply the same crop box to all pages to keep every page a consistent size - handy for standardizing a scanned document before printing.
