Frequently Asked Questions

No, the original content quality remains intact. The tool only adjusts the page dimensions and may:

  • Add margins (white space) when scaling down
  • Crop edges when using "Fill" mode on larger content
  • Maintain original image and text resolution
  • Preserve vector graphics and fonts

For best results, use "Fit" mode to ensure no content is lost.

This tool applies the same page size to all pages in the document. For selective page sizing:

  1. Use Split PDF to separate pages first
  2. Process different sections with different sizes
  3. Use Merge PDF to recombine
  4. For advanced control, try PDF Multi Tool

These scaling modes handle content differently when page size changes:

Fit (Recommended)

Scales content to fit within new page boundaries. Adds margins if needed. No content loss.

Fill (Crop)

Scales content to fill entire page. May crop edges if aspect ratio differs. Good for images.
