No. The tool fits the visible source page inside the new dimensions without changing its proportions. If the source and target shapes differ, white space appears around the content.
Yes. Choose Custom size and enter width and height in millimeters, from 10 to 1000 mm each. Swap the values if you want the opposite orientation.
The resized PDF embeds visible page content on new pages. Links, interactive form fields, annotations, and digital signatures may not carry over. Review the result before sharing.

Change PDF Page Size Without Cutting Off Content

Use this free PDF page resizer to make a document's pages consistent for printing or sharing. Choose A4, US Letter, or a custom width and height in millimeters. The tool scales each visible source page evenly to fit the new page and centers it, so text and images keep their proportions. You can preview each source page against the new dimensions before making the PDF, then inspect the actual output before downloading.

This changes the physical page dimensions. It does not aim to reduce file size; for that task, use Compress PDF. It does not trim the visible area; use Crop PDF when you need to change which part of a page is shown.

How Does the Content Fit?

The visible page area is scaled proportionally until it fits inside the new page. The tool centers it and adds white space when the source and target have different shapes. It does not deliberately clip or stretch the content. Small text can become smaller when a large source page is fitted to a smaller target, so inspect the finished PDF before printing.

What Happens to Interactive PDF Features?

The new page contains the visible PDF content. Links, form fields, annotations, and digital signatures may not remain interactive or valid. Keep your original if those features matter.
