Compress a PDF
Reduce PDF file size by rewriting and optimising the document structure.

About this tool
Compress PDF is part of the MyShopBuy pdf tools collection — a free suite built for people who need a reliable result in seconds, not another signup form. Reduce PDF file size by rewriting and optimising the document structure. Processing happens entirely inside your browser using modern web APIs, so nothing is uploaded, queued or stored. That makes it fast enough for daily use and safe enough for sensitive documents.
There are no watermarks, no file-count limits and no paywalls. If you use it often, create a free account to keep favourites and history in sync across your devices.
