How to crop or resize a PDF
Trim visible edges precisely, or give mixed pages one consistent canvas.
Apply settings to the current page when layouts differ, or to all pages for a consistent document. Rotated and mixed-size pages are measured in the orientation shown in the preview.

3
Set scope and preview
Apply the change to the current page or all pages, then review clipping, space, and optional scaling.
4
Validate before download
The saved file is reopened to verify its header, page count, boxes, dimensions, and rotations.
Aspect-preserving content scaling
Scale-to-fit uses one proportional transform, centers the page content, and avoids stretching. Supported annotation geometry follows the same transform so links and comments remain aligned.
Review specialized PDF features
Complex forms, digital signatures, portfolios, scripts, and viewer-specific features can react differently to page transforms. Review important documents after downloading.
Ready after the app loads
Once this page and its PDF engine are loaded, cropping, resizing, previewing, validation, and download do not require a document upload. Keep the tab open while processing larger files.
