Crop PDF Pages to Custom Margins & Dimensions — Live Preview
Trim unwanted white space from any PDF with a visual cropper. Drag the crop rectangle directly on a live page preview, pull its handles to resize it, or type exact margins in points — the same crop is applied to every page of the document, scaled to each page size. Use it to tighten up scans, cut out sidebars and ads, or remove excess whitespace before printing. Everything runs locally in your browser: your file is never uploaded, and text inside the selection stays fully selectable.
Frequently Asked Questions About Cropping PDFs
What units does the crop use?
Margins and dimensions are shown in PDF points (1 pt = 1/72 of an inch). The live rectangle and the numeric fields always show the same values, so you can draw a crop by hand or type exact margins.
Will cropping remove the content or just hide it?
The cropped PDF's page size is set to your selection, so everything outside it is clipped from display, printing, and export. The underlying content outside the box is not rewritten — only the visible page area changes.
Can I crop each page differently?
This tool applies one crop to every page for a consistent result — ideal for trimming white margins from scans and screenshots. For per-page control, split or remove pages first, crop, then merge them back together.
Is there a file size limit?
No hard limit — the only constraint is your device memory. Cropping rewrites page boxes without re-encoding content, so it is fast even for large documents and the file rarely grows.
What if my pages are already rotated?
The preview shows pages without their stored rotation so the crop rectangle lines up with the page geometry. Cropping still works on rotated pages — the crop is applied to the page box before the stored rotation, so use the Rotate PDF tool first if you want the crop to match the orientation you see on screen.
