Frequently Asked Questions about Crop PDF Pages
Does cropping reduce PDF resolution or text clarity?
No. Cropping modifies the page bounding box (MediaBox / CropBox) without rasterizing or recompressing vector text or images.
Can I crop all pages or specific pages?
You can apply uniform margin trimming across all pages or specify target page ranges.
Can cropped areas be undone in the original file?
Your original file on your computer is never touched. DocxLab produces a new, separate cropped PDF file for download.
