How the Resize PDF Tool Works

Our Resize PDF tool intelligently adjusts page dimensions while keeping your content readable, properly aligned, and optimized for printing or sharing.

Page Analysis: Each page is analyzed to detect its original size, orientation, and margins.

Flexible Page Sizes: Resize PDF pages to standard formats like A4, A3, Letter, Legal, or custom dimensions.

Smart Scaling: Choose between fit, fill, or stretch modes to control how content adapts to the new page size.

Margin Control: Add or remove margins to improve layout, printing accuracy, or readability.

Quality Optimization: Optimize file size and visual quality with balanced compression settings.
