A PDF compressor is a software application that reduces the size of a PDF file without compromising its quality. PDF files can be quite large, especially if they contain images or high-resolution graphics. By compressing a PDF, you can make it smaller and easier to share, email, or upload to a website.

How does a PDF compressor work?

PDF compressors work by removing unnecessary data from the PDF file. This can include things like unused fonts, whitespace, and redundant information. The specific techniques used for compression vary from one compressor to another. However, most compressors use a combination of lossless and lossy compression techniques.

Lossless compression refers to a method of compression that does not lose any data from the original file. This type of compression is often used for text files, as it ensures that the text will be readable after it has been compressed.

Lossy compression refers to a method of compression that does lose some data from the original file. This type of compression is often used for images and graphics, as it can achieve much higher compression ratios than lossless compression. However, it is important to note that lossy compression can degrade the quality of the image or graphic.
