    Compresses PDF files with high quality

    Date: Sep 24 2025
    Summary

    Despite the app's weaknesses, it still does a good job of compressing PDF files. I recommend selecting the "Small File Size" compression level if compressed images don't have a significant impact on reading. I prefer using the "Custom" setting, although it requires several adjustments to achieve the desired compression level.

    Positive

    In my daily life, I send a lot of PDF files via email and other social media apps. Sometimes the files are too large to send quickly. Thanks to PDF Compressor, the PDF files become smaller, and the quality of images and text isn't significantly affected.
    This app offers four compression levels: Small File Size, Medium File Size, Large File Size, and Custom. It can compress multiple PDF files at once.

    Negative

    The app is only compatible with Mac and Windows; there is no online tool or version for Android and iOS.
    Only supports one language – English.
    The app compressed a 30.09 MB PDF file to 3.98 MB using the "Small File Size" compression level, and the color of the images in the file eventually becomes black and white.
