How to Crop All Pages of a PDF at Once on iPhone

TL;DR

With PDFCrop Pro you can edit one page's crop and apply it uniformly to every page of a multi-page PDF in one tap — turning a hundred-page cleanup into a single action.

Steps

Open a multi-page PDF in PDFCrop.
Crop one page — auto or manual — the way you want them all.
One-tap apply to all pages.
Skim the pages to confirm the crop fits throughout.
Export the whole cropped document.

Why it works this way

Most multi-page PDFs share one layout, so cropping each page by hand is pure repetition. PDFCrop lets you perfect one page and propagate that crop across the whole document in a tap — the difference between minutes and seconds on a long scan. It’s a Pro feature because batch is where the real time savings live.

Tips & edge cases

Pick a representative page to set the crop before applying to all.
Consistent scans batch cleanest; mixed layouts may need spot fixes.
Pro unlocks batch plus unlimited exports.

FAQ

Can I crop every page the same way at once? Yes. Edit one page, then one-tap apply the crop to all pages. This is a Pro feature.

What if pages vary slightly? Batch works best on consistent layouts; you can still tweak individual pages afterward.

Is batch crop free? No. Batch apply-to-all-pages is part of PDFCrop Pro; the free tier crops a single page.
