What if I need to crop different amounts from different pages?

The crop operation applies uniformly to all pages. If you need different crops for different pages, you have two options: first, extract the pages that need different crops into separate files, crop each file individually, and then merge them back together. Or, specify a crop amount that works for all pages (like removing a consistent scanner border). For documents with mixed content, the consistent crop is usually the cleanest approach.

What units can I use to specify the crop amount?

You can specify the crop in several units: inches (e.g., 'crop 0.5 inches'), centimeters (e.g., 'crop 1 cm'), millimeters (e.g., 'crop 10 mm'), or as a percentage of the page size (e.g., 'crop 10% from each side'). FlowPDF converts these to the correct pixel coordinates based on your PDF's page dimensions. If you don't specify units, FlowPDF assumes the values are in points (1/72 inch) by default.

Does cropping affect the document's text layer or file quality?

Cropping removes the edge portions of each page — including any text, images, or content in the cropped area. The remaining content stays exactly as it was, with no quality loss or re-encoding. If you crop a page that has form fields or annotations near the edge, those elements are removed if they fall into the cropped area. The text layer for the remaining content stays intact and searchable.

Can I crop only a specific range of pages instead of the whole document?

Yes — you can specify a page range for the crop. For example, 'crop 1 inch from pages 3-8' or 'crop the first 5 pages by 0.5 inches.' This is useful when only certain pages have scanner artifacts or inconsistent margins, while the rest of the document is already correctly formatted.

Does cropping reduce file size?

Yes — cropping can significantly reduce file size, especially if you're removing large borders from scanned documents. The cropped areas contain content that is removed from the PDF, so those pixels or objects no longer contribute to the file size. For image-heavy scanned PDFs with wide scanner borders, the reduction can be substantial — sometimes 10-20% of the total file size, depending on how much you're cutting away.

Crop PDF Pages Online — Trim Margins, Remove White Space, Free

Scanned documents almost always come with extra baggage. The scanner bed captures more than the page — you get a dark border, a skewed edge, or an uneven white margin that makes the document look unprofessional. Digital documents from different sources have inconsistent margins, making them awkward to print or read. FlowPDF crops a uniform margin off every page of your PDF, trimming away the excess and giving you clean, consistent pages. You specify how much to remove — say 'crop 0.5 inches from all sides' or 'remove the top 1 inch and bottom 0.5 inches' — and FlowPDF applies it to every page equally. This is not a manual rectangle selection per page; it's a consistent crop across the entire document, which is exactly what you need for printed materials, binding preparation, or simply making a document look polished. For PDFs with varying content positions on each page, you can also describe the crop area as a percentage of the page size.

Frequently asked questions

crop-pdf removes content from the edges of each page — it's a trim operation that makes the page smaller by cutting off parts of the existing content. resize-pages changes the entire page size while scaling the content to fit the new dimensions. Use crop-pdf when you have unwanted margins or scanner borders that need to be removed. Use resize-pages when you need to standardize page sizes (like converting Letter to A4) while keeping all content visible.
