Crop PDF

This tool runs entirely in your browser: your PDF is never uploaded to a server. PDF.js renders each page so you can see exactly what you're working with, and you define the crop by entering margin values (in points, inches, or millimeters) for each side of the page, or by adjusting a visual crop overlay.

On export, PDF-lib sets each page's CropBox — a standard PDF property that defines the visible viewing/printing area — to your specified boundaries. Crucially, the underlying page content itself is not deleted or redrawn.

Because cropping only adjusts the CropBox rather than deleting content, the crop is non-destructive: opening the cropped file in another tool and clearing or expanding the CropBox would reveal the original full page again.

Your files are uploaded over an encrypted (SSL) connection. We don't store, read, or share the contents of your files — they're processed to generate your result and are not retained on our servers afterward.

• Removing excess white margin from a scanned page before printing or sharing.
• Cutting a PDF page down to just the relevant content area (e.g., isolating a chart from a full report page).
• Standardizing inconsistent page margins across a document assembled from multiple sources.

• Cropping too aggressively and cutting off content near the edge — preview the crop area carefully before applying it, especially on pages with content close to the margin.
• Applying one crop setting uniformly to pages with different layouts — check whether your document needs per-page or uniform cropping.

• Crop conservatively first — you can always crop further, but you can't restore content that's been cropped away without starting from the original file.

We respect your privacy. All files are processed securely and are never sold, shared, or used for anything beyond generating your result.
