Optimizing PDFs
How to Optimize PDFs for the Web
To re-size your PDF prior to upload:
Before uploading a pdf you should check its file size and use a program or tool to compress and re-size the file.
You can use a free tool like https://www.pdf2go.com/compress-pdf to resize your PDFs. This tool allows you to resize your PDFs for free (there are a number of other great free tools on this site also).
OR, if you already have Adobe Professional, do this:
Open the PDF in Adobe Professional (not Reader) and choose:
File > Save As Other > Optimized PDF
OR
File > Save As Other > Reduced Size PDF
Then upload your PDF to Site Apex.
