Frequently Asked Questions
Common queries regarding client-side PDF page resizing.
Q.How does the PDF resizing work?
The tool modifies the media box and crop box geometry dimensions of each page, then scales or centers the existing page content overlay to fit the new page size.
Q.Will my PDF page content get cut off?
No. Our engine calculates the optimal scale factor and automatically centers the original content to fit within the new boundaries, maintaining the original aspect ratio.
Q.Can I resize multiple PDFs at once?
Yes. You can upload multiple files in batch, select the desired page size, and download the resized documents compiled inside a zip archive instantly.
Q.Is it safe to resize confidential documents?
Absolutely. All resizing computations occur 100% client-side in your browser cache. No document content is uploaded to any server or third-party storage.
