What Happens to Your File

OxnaPDF wraps each target page in a new page canvas of your chosen A4, US Letter or custom dimensions in browser memory and transforms the existing vector page content to either scale proportionally or sit centred at 1:1 scale.

All vector text, paths and embedded images keep their native sharpness without rasterisation, and your original PDF remains unchanged on your device.

Limits

  • Accepts unencrypted PDFs up to 100 MB and 500 pages, resizing all pages or a custom page range.
  • Supports A4, US Letter or custom dimensions from 36 pt to 14,400 pt (0.5 in to 200 in) entered in points (pt), millimetres (mm) or inches (in).
  • Orientation can be set to Auto (matching each source page's aspect ratio), upright or wide.

Good to Know

  • Keep Auto orientation enabled when your PDF mixes tall text pages and wide tables so each page is resized onto the matching A4 or Letter orientation.
  • Choose Scale to Fit when converting between A4 and US Letter for printing, or Centre Without Scaling when adding wider margins around an existing page.
  • If you want to trim away existing white margins rather than placing the page onto a new paper size, use Crop PDF instead.
