You can also drag and drop the files directly into the website window to upload them automatically. Most services work in a similar way, however, by allowing you to upload the file, select the quality, and download the compressed file afterwards. Various services exist to compress PDF files online, such as I Love PDF. This poses a serious security risk for any documents that may contain personal data, and you should only use online compression sites for files that you would be happy to share publicly. Using these services involves uploading the file to a remote server, where the file could remain in place for a period of time. If you want to use an online service like this, however, you should only do so with non-sensitive documents. If you don’t want to download additional software to compress your PDF file, you can use various online PDF compression services instead. That way, you'll have two files: a Word document you can continue to edit and a PDF file you can share.
Important: Give the PDF a different name than the original document.
In the Save As box, type a name for the file. You’ll need to open this in Preview afterwards to preview what (if any) noticeable changes in the quality have been made by the app. Or, you can also save a file by clicking the Save icon in the ribbon. Preview will immediately save an updated, compressed version of your PDF document.
