Complete PDF Manipulation Tool: Rotate, Crop, and Resize PDFs
Our PDF Rotate/Crop/Resize tool provides comprehensive PDF manipulation capabilities entirely in your browser. Unlike other online tools that require file uploads to external servers, this tool processes your documents locally, ensuring complete privacy and security.
Key Features
Page Rotation
Rotate PDF pages by 90°, 180°, or 270° to correct orientation issues or adjust document layout. Perfect for scanned documents that need reorientation.
Smart Cropping
Three cropping modes: manual crop with interactive overlay, automatic margin detection, or no cropping. Remove unwanted borders and focus on important content.
Document Resizing
Scale pages from 50% to 200% of original size or convert to standard page sizes including A4, Letter, and Legal formats.
