Compress PDF documents using the application we have developed for you. The PDF compression application has three modes of operation: "Low", "Medium" and "High". The "Low" compression mode optimizes the internal structure of the document and removes redundant metadata from the PDF document. The "Medium" mode performs the same actions as the "Low" compression mode and additionally reduces the quality of images within the document by 50%. In the "High" compression mode, images are compressed by 75% and the maximum resolution for images will be 150px.

Why do I need to compress PDF documents? For example, you regularly receive invoices from your partners for payment of services in the form of PDF documents. You need to put these documents in an archive, but each document contains a logo or a graphic diagram that takes up a lot of space on your hard drives. The PDF document compression application will help make your documents more compact and save extra space in your repositories.
You can compress PDF documents on any operating system: Windows, macOS, Linux or Android. Just open the page of this application in a web browser, load your document, select a compression mode and click the "Compress" button. In a minute, you will receive a link to download the compressed document.
