How to Compress PDFs in Windows 10

PDF compress

PDF (Portable Document Format) is a universal document format you can open in all PDF readers. So this is a good format for email document attachments. However, there’s a file size limit on what you can attach to emails. If you attach multiple PDFs that exceed the maximum file size, you can compress them to reduce their file size as follows.

Select an output folder, or path, by pressing the folder button at the bottom of the window. If you don’t choose a specific folder, it will save the compressed PDF in the same path as the original. Click the Compress Images check box and drag the bar further right to retain more image quality. Then press the Compress button at the top of window to cut the selected PDFs down to size.

Open the folder you saved the compressed document to to check its new size. You could get quite a reduction in megabytes. For example, I compressed a PDF from 1.7 MB to 338 KB, which is less than a third of the original file size.
