export crisp images with a small digital pdf preset?

[kat]

Is there a way to export crisp images with a small digital pdf preset which comes out at 1.1mb?

Page 1 has a pale background box outside the svg, and page 6 & 7 have blurry images. If I export high quality digital pdf everything is fine but the pdf size is 8.9mb. I've included the images

I need to make images pngs the exact size they appear are in Affinity Publisher. How do I do this? Then I can not reduce res in export pdf.

Note: I've opened image in Pixalmator Pro and applied "Super Resolution" and cropped which did a great job and helped image sharpness.

You can try right clicking on the image on the page in Publisher and selecting Rasterise but that will be rasterised to your documents DPI, so depending what that is, it may be best to open each image in Affinity Photo and resize the images to the needed size and export them.  Then place them on the page in Publisher.

If that still produces a larger PDF than you'd like, try lowering the JPG compression on the Export window and that should give you a smaller export.  I'd start by lowering the JPG compression option by 5 each time and checking the size and quality of the exported PDF.

I think you meant to suggest lowering the JPG quality (or raising the amount of compression). Because JPG compression is lossy the quality will drop if you increase the amount of compression, but the saving in file size can be quite significant even if you lower the “quality” by only a few percentage points.
