If you were trying to reduce a file below a particular threshold – say you needed the final file size to be 80 percent smaller, but it only reduced to 40 percent of its original size – the app allows you to cancel the compression and start over. One handy feature of PDF Squeezer is its verification for reduced files.
PDF Squeezer simply has a ton of fine-tuning you can do to find that sweet-spot for a reduced PDF that retains as much (or little) quality as you like. You can also choose the final resolution of a PDF, convert its color profile, eliminate annotations, choose a sampling rate, and convert to bitmap if desired. This is really handy when you have something like a text document that doesn’t need to be pixel-perfect. It also has an option to limit a PDF’s image quality – allowing you to purposefully reduce an image’s quality to make the reduced file size even smaller when it’s compressed. It can reduce size of PDF by up to 90 percent. One of the best options is PDF Squeezer for Mac. Your best bet is to find a reliable app to compress PDF file sizes without harming the document.
