PDF Compressor

PDF compressor is a free online tool that compresses large-sized pdf files into small sizes. Compression is a process that optimizes bits and bytes to reduce the overall size of the file. Usually, compression compromises the quality of the document as we see in the case of images. When we compress the size of an image then the quality of the image goes down. So, the same is for digital documents. Don’t worry you don’t have to lose too much quality because here we have many options for the compression of PDF files.

Further, there are two types of compression:

  • Lossless Compression: It is for documents that contain text. The algorithm generates reference points for patterns of text, saves them, and then puts them back to your PDF file.
  • Lossy Compression: This type is for images and graphics. You can use it to reduce the size of image files by eliminating informational bits. It provides you a compressed image with a small size and a low quality.

You should compress your PDF file using desktop software. It will give you more control over downsampling. It helps you to focus on the details and fine-tune for the compression. Software is perfect when you want to reduce the size of the PDF as much as possible. It is great when you need to email a PDF.
