How to compress the file size of PDF? PDF has become a widely used document format due to its good compatibility and stability. However, since PDF files may contain images, large amounts of text and complex layouts, the file size is often large. This not only puts pressure on storage space, but also greatly affects the transmission and sharing of files. In order to improve work efficiency, we often need to compress PDF files. This article will introduce four simple and effective PDF compression methods to help you easily reduce file size and improve daily office efficiency.
Method 1: Use online tools for compression
Online tools do not require downloading any software, and can quickly complete PDF compression through a browser, which is very suitable for temporary or one-time compression needs.
