The Technical Details
The Rotation utility runs locally by updating page descriptors inside the document stream. Using pdf-lib, the tool loads the PDF buffer, parses page collections, and isolates target indexes.
Rather than re-encoding or scaling image rasters (which damages quality), the library simply updates the page’s /Rotate dictionary key value with the specified angle. This absolute metadata update runs instantly, maintaining visual fidelity and file sizes.
Frequently Asked Questions
Can I rotate only specific pages?
Yes. You can rotate all pages, only odd pages, only even pages, or enter a custom list of page numbers and ranges.
Are rotation angles cumulative?
No. Each page's rotation is set absolutely. Applying 90° will set the page to exactly 90° regardless of its current orientation.
Does rotation change the original file?
No. The tool creates a new PDF with the specified rotations applied. Your original file is not modified.
Is my PDF processed on a server?
No. Rotation is performed entirely in your browser using pdf-lib. Your file stays on your device at all times.
