What is a pdf compression tool?

A PDF compression tool is a software application that reduces the file size of a PDF document by removing unnecessary elements and compressing data within the file. This can include things like embedded images, fonts, and metadata.

There are different types of compression techniques that can be used to compress a PDF file, such as lossless and lossy compression. Lossless compression preserves the quality of the original file, but the reduction in file size may be less significant. Lossy compression, on the other hand, may result in a greater reduction in file size, but at the cost of some quality loss.

PDF compression tools can be used for a variety of purposes such as sending large PDF files via email, uploading PDFs to a website, or saving space on a hard drive. Compressing PDFs can also be useful for reducing the time it takes to download and view the document.
