We are generating PDF from HTML using Aspose v21.8 and it is reducing the line break spaces between the content.
Please have a look at the attached PDF and JSFiddle link, the HTML has more spaces while PDF has reduced the line break spaces from it between.
I am also attaching a link to our sample app which you can use to generate the same PDF.
