The PDF Margin Adjuster adds extra space around the content of your PDF pages. Specify additional margin in points (72pt = 1 inch) for top, bottom, left, and right sides independently. The page size expands to accommodate the new margins while preserving all original content at full quality.

Technical Guide
Uses pdf-lib embedPages to embed original pages into new, larger pages. New page dimensions are calculated as original width + left + right margins, and original height + top + bottom margins. The original page content is embedded at position (left, bottom) to create the margin offsets. Top margin adds space above, bottom below, left to the left, and right to the right. All content is preserved as embedded vector data.
