Compress PDF

Compress PDF — reduce PDF file size without losing quality, right in Chrome. Make a PDF smaller for email, uploads or storage. Open a PDF in Chrome and a Compress PDF button appears right in the PDF toolbar, next to Chrome's own download and print buttons. One click compresses the document you're reading and takes you straight to the smaller download — no saving it first, no re-uploading. For PDFs on your computer, the toolbar icon opens the full ZonePDF compressor. Compress the PDF you're viewing 1. Open any PDF in Chrome 2. Click the blue Compress PDF button in the toolbar 3.
