Extra Tips: How to Compress PDF File Size While Saving It

Instead of compressing PDF files later on, actually, we can also choose to determine a smaller size for the PDF document while saving it. Here bring you several tips on compressing PDF files while you are going to save the PDFs.

Tip 1. Avoid to Scan PDFs

Normally, the scanned PDFs would have larger sizes than the eletronically converted ones when we need to save several documents into a single PDF. Thus, instead of printing and scanning the original documents on paper for combining them, you can actually convert them online using those online PDF converters such as EasePDF. This can greatly reduce the size of the PDF.

Tip 2. Use "Save As Reduced Size PDF" in Adobe Acrobat 

Instead of using the "Save As..." option to output the edited PDF, use the "Save as Other" and you can find a "Reduced Size PDF..." option in its menu. In this way, you can compress the PDF file even while saving it.

Finally, hit the "Save" icon and the PDF will be compressed to a smaller size.
