How do I convert a US Letter PDF to international standard A4 size?

Select A4 (210×297 mm) as the target dimension. The engine recalculates the /MediaBox and /CropBox coordinate matrices and centers the content with balanced margins.

What is the difference between "Fit with Margins" and "Stretch" page scaling?

"Fit with Margins" scales content proportionally to fit the new dimensions without distortion. "Stretch" forces the content to fill the exact target aspect ratio, which may alter proportions slightly.

Which international paper sizes are supported for PDF conversion?

Standard sizes include ISO A4 (210×297 mm), US Letter (8.5×11 in), US Legal (8.5×14 in), ISO A3 (297×420 mm), and Tabloid (11×17 in).

Will resizing pages degrade high-resolution vector text or CAD drawings?

No. Vector fonts, line art, and PDF drawing operators scale losslessly at any target page size.

How do I standardize a PDF that contains mixed page sizes into a uniform format?

Apply the resize tool across all pages in the document. The engine standardizes every sheet to the exact same physical dimensions.
