Why do my PDF pages have different sizes?

PDFs assembled from multiple sources, scanned documents, or files created across different systems often contain mixed page sizes. For example, a merged report might have A4 pages from one source and Letter-size pages from another. This causes printing issues and looks unprofessional.

What happens to content that doesn't fit the new size?

You can choose to scale content proportionally to fit the new page size (content is resized) or keep content at original size and adjust the page box (content may be cropped or have extra margins). Scaling preserves all content while changing its size; adjusting the page box preserves exact content dimensions.

Will this fix printing problems?

Yes. Printers handle uniform page sizes much more reliably than mixed sizes. After standardizing, your PDF will print correctly without scaling surprises, misaligned content, or paper tray switching issues.

Can I handle mixed portrait and landscape pages?

Yes. The tool can optionally rotate landscape pages to portrait (or vice versa), or maintain the original orientation while standardizing the dimensions. This flexibility handles documents with mixed orientations.
