Image to PDF Conversion: Optimize File Size

When converting large or high-resolution images to PDF, the resulting file size can be quite large.

In order to reduce the size of the final PDF, we suggest:

  1. Reducing the size of the initial image where possible.
  2. Reducing the DPI (dots per inch) / resolution of the image prior to conversion.

Image DPI can often be reduced to somewhere around 90 without posing any adverse effects on visuals in the resulting PDF.
