The reason why the PDF files are so big is because the writing is drawn by a series of plain circles of different sizes that are linked together (image 1 in attached file). That's a nice trick for a nice handwriting fidelity, getting different kinds of pen and for the eraser to work like intended.

In order to reduce the PDF, Goodnotes would have to :

- identify every single character or drawn forms. (I don't think that a trivial routine to code...)
- merge circles that form that particular shape (image 2 in attached file) and everyone who worked in a vector based program like Illustrator or Affinity Designer would know that there are cases where merging doesn't work like we want...
- simplify the path by removing the while still being faithful to the path (image 3 in attached file).

All that in an automatic exporting routing. When simplifying path in an app that can do the job, the artist has control over the procedure. So making a flawless simplifying curve routine would be a very difficult beast to tacle :)

But I still have voted for this suggestion :D

I agree to this idea. As soon as my files have some pages, their pdf exports grow to more than 10 mb, which makes it hard to share them via mail, which is essentially sometimes, since many university students use goodnotes, to accomplish tasks, they have to hand in!

I also agree there should be an option to downsize the export PDF. I use this function to share notes with collages which don't use GoodNotes and if we have a longer meeting I'm not able to send all in one file due to size. That's annoying.

This for me is the only real downside with this App for what I use it for which is mainly site work including surveys, notes on pictures then exporting either via email or cloud - the files soon become massive.
