Resizing PDF pages to A4 ensures consistent printing and professional appearance for documents that will be submitted or printed on A4 paper.
Navigate to the crop tool which includes page size resizing functionality.
Choose A4 (210 × 297 mm) from the preset size options. The tool scales all content proportionally to fit the A4 page.
Tip: For US Letter → A4 conversion, the scale is approximately 97% — almost no visible difference in content size.
Click Apply to All Pages. Download the A4-formatted PDF, ready for printing or submission.
A4 (210 × 297 mm) is slightly narrower and taller than US Letter (216 × 279 mm). Both are near-identical for most documents.
