Questions & answers
How do I resize a PDF to A4 or 8.5 x 11?
Choose A4 or US Letter under Paper size, select orientation and outer margin, then resize and inspect a copy. US Letter measures 8.5 x 11 inches. Selected pages must be upright.
Does changing paper size reduce a PDF to 200 KB?
No. Paper dimensions and file size in bytes are different. Use compression or size-based splitting when the destination specifies KB or MB, and verify the actual output size.
Will resizing stretch the page content?
Content is scaled proportionally to fit the chosen paper. Different aspect ratios can leave blank space around it.
