Does cropping delete content?

No. Cropping adjusts the PDF's crop box, which hides content outside the defined area but does not remove it from the file. The hidden content remains present and can be revealed by adjusting the crop again.

Will the crop apply to all pages?

By default, yes — the same crop dimensions are applied uniformly to every page. You can also target specific pages if different sections need different margins.

Can I set exact millimetre margins?

Yes — use the numeric input fields to enter precise margin values in millimetres or points, useful when you need to hit a specific page size standard.

How do I remove white space from a PDF for free?

Upload your PDF to PDFToolsNow, drag the crop handles to trim the white margins, then click 'Crop PDF'. The trimmed file downloads immediately — no account or software required.

Can I crop a PDF to a specific page size like A4?

Yes. Use the numeric margin fields to enter precise values that result in a standard page size. Measure the current page dimensions from the preview and calculate the margins needed to reach A4 (210 × 297 mm) or your target size.

Will cropping change the file size?

Cropping typically does not significantly reduce the file size because the page content remains in the file — only the visible boundary changes. To reduce file size, use a PDF compression tool after cropping.

What is crop pdf?

PDF cropping adjusts the visible area of each page by setting a crop box — a rectangular boundary that defines which portion of the page is displayed and printed. Any content outside the crop box is hidden from view but remains in the file, which means the crop is reversible if needed. Cropping is commonly used to: remove the oversized white margins that scanners add around a scanned document, trim the publisher-imposed margins from academic papers and ebooks to better fit an e-reader screen, strip repeating headers and footers added by a print-to-PDF driver, focus attention on a specific region of a technical drawing or map, and reduce the visual padding on presentation slides converted to PDF. PDFToolsNow provides two ways to define the crop area: a visual drag-handle selector overlaid on a live page preview for intuitive placement, and numeric margin fields for situations where you need a precise dimension in millimetres or points. The same crop dimensions are applied uniformly to every page by default, ensuring consistent margins throughout the document. Because cropping only adjusts the crop box and does not re-encode or delete page content, there is no quality loss and the hidden area can be recovered by re-opening the PDF and adjusting the crop.
