Frequently asked questions
How do I convert a PDF to A4 size?
Select the file, choose A4 as the page size and press resize — every page is set to A4.
Will content be cropped when resizing?
No. Each page's content is scaled proportionally to fit the new size and centered on the page.
What does automatic orientation do?
It keeps each page's orientation, so landscape pages stay landscape and portrait pages stay portrait.
Can I resize several files at once?
Yes. Select multiple PDFs and the same size is applied to all of them.
How do I resize a PDF to 8.5 x 11 inches?
Choose Letter, which is 8.5 × 11 inches, as the new size and press resize.
Does resizing PDF pages reduce the file size?
No. This tool changes the page dimensions, not the file size. To make the file smaller, use Compress PDF.
