Complete Guide to Crop PDF
Crop PDF Pages to Any Size Online
Our free Crop PDF tool lets you define the exact visible area of any PDF page, trimming away margins, whitespace, or unwanted content with pixel-level precision. Use the interactive drag handles in the visual editor to set your crop region, preview the result on any page, and apply the crop to a single page, a range, or all pages at once. All processing happens in the browser — files are never stored beyond 60 minutes, and no watermark is added to your output.
What You Can Achieve with PDF Cropping
PDF cropping is more versatile than it sounds. Remove oversized margins from scanned documents where the scanner captured too much white border around the page content. Focus on a region of a technical diagram, blueprint, or map by cropping away everything outside the area of interest. Standardize page sizes across a mixed document where different pages have different content boundaries. Prepare slides for screen sharing by cropping PowerPoint-converted PDFs to remove empty space at the top and bottom. Create visual excerpts by cropping to show only the relevant chart or table from a data-heavy page.
How Cropping Works in PDFs
PDF cropping sets the "crop box" within the PDF structure — this defines the visible area when viewing or printing the document. The original content outside the crop box is preserved (not deleted), meaning you can always re-open the PDF in another tool and recover the full page if needed. For a permanent, irreversible crop, use our tool to crop and then re-save the PDF. After cropping, you may want to use our Rotate PDF tool if any pages need orientation correction, or compress the final PDF to reduce file size for sharing.
