How to Compress Image in PDF to Reduce File Size


• Filed to: Edit PDF

Do you have a need to compress images in your PDF files? There are a lot of programs out there that promises to be able to do that. However, you will find that most of these programs will compress your files at the cost of the quality of your document. For example, if the document you were hoping to compress had high definition photos, you’ll notice an obvious lacking in photo clarity. In some cases, it might even cut some parts of the actual document! This is not good, especially if you’re looking for something quick and simple that you can send and or store at a more reasonable file size.
