Letter and A4 are close but not identical — Letter is wider and shorter. Printers handle the mismatch by scaling or cropping, which shifts margins and can clip content near the edges. Converting the document to the destination size beforehand avoids leaving that decision to whichever printer it lands on.
No — content is scaled proportionally to fit the new page, so nothing stretches. What changes is the margin, since the aspect ratios differ slightly. Going from A4 to Letter or back is visually minor; jumping between very different sizes like A5 and A3 is more noticeable.
Yes, provided the PDF contains real text and vector graphics — those scale cleanly to any size. Scanned pages are images, so enlarging them softens the result exactly as enlarging a photo would. Text-based PDFs can be resized freely; scans are better kept near their original dimensions.
