I want to reduce the size of the below file

This is just crazy, considering Apple to be such a premium company and goodnotes being one of the most recommended apps in that field. There are so many flaws, which I would never find on a similar Android app.

Yeah, same here. I'm two weeks into lecture and already have over one GB of files, the files are getting too big to handle. iPad is stuttering. Please implement low quality pdf export please and/or some sort of live compression.

do not use fountain pen

And now almost 4 years
And nothing change

I read somewhere that Goodnotes at the moment only takes advantage of the iOS native PDF generating API which doesn't allow compression. Would be essential for our work if Goodnotes would make use of a more sophisticated built-in PDF API which at least allows levels of compression on export, maybe compressed / smaller file sizes of native goodnotes documents as well as we also export native goodnotes documents as plan status.

I also run into the problem of file sizes being too large. I use GoodNotes for work and take notes, fill out forms and annotate pictures for clients. I import a pdf brochure and try to email the package to the client but it’s huge! It would be so helpful to be able to change quality, or optimize file size when exporting/emailing

This is a practical solution which uses a simple LaTeX script to compile all exported images from a GoodNotes notebook into a lower memory pdf. You can Export your notebook as a set of images by going to "Export ALL", selecting the 'Image' format, then under options select "export images as zip file"

! Export in small size is A much needed feature required in good-notes

This would be great. My 3 page PDF was about 10mb (one <1mb image included). This won’t be feasible when exporting notes to PDF in order to share them via email.

yes, I am agree with this.
yes it nice to writing on goodnotes 5 with auto advance compare to noatbility, I prefer goodnotes's auto advance.

but after I writing about 16 pages, the file size is about 150MB.
it is really crazy.
I scan my 300 pages book only take 35-75MB.

but 16 pages = 150mb???

are you serious??

My GoodNotes files of 20 pages or so usually generate a PDF file of 20Mb in size. This is far too large! Using Acrobat Pro's "optimize scanned PDF" feature, this reduces to 1Mb or less. GoodNotes should allow some kind of "quality" option for PDF export that permits lower-resolution output when desired.
