Browse All ToolsWhat Is PDF Cropping?
PDF cropping adjusts the visible area of PDF pages by trimming margins, removing whitespace, or focusing on a specific region of each page. This changes what viewers see when they open the document, hiding the areas outside the crop boundary without permanently deleting content.
Cropping is commonly used to remove excess margins from scanned documents, trim whitespace around content for tighter layouts, focus on specific regions of technical drawings, or standardize page dimensions across documents from different sources.
One23PDF's cropping tool lets you set precise crop boundaries using visual controls or exact measurements. Apply the same crop to all pages or customize individual pages. All processing happens locally in your browser with no file uploads, no account required, and no restrictions on file size or page count.

One23PDF vs. Other PDF Cropping Tools
PDF cropping is a feature typically found only in premium tools like Adobe Acrobat Pro or Foxit Editor, both of which require paid licenses and desktop installation. Free online cropping tools are rare, and those that exist usually upload your files to remote servers with significant limitations.
One23PDF offers precise PDF cropping entirely in your browser — no file uploads, no software installation, and no cost. Set exact crop dimensions, preview the result, and download your optimized PDF in seconds. Your documents never leave your device.
Whether you're standardizing scanned document margins, preparing print-ready layouts, or trimming content for specific presentations, One23PDF gives you the control of desktop software with the convenience and privacy of browser-based processing.
