    Why use this tool

    A smaller PDF can be easier to attach or upload. Compression results depend on the document, and size reduction can affect image detail.

    Frequently asked questions

    How much smaller will my PDF become?
    There is no fixed reduction for every document. The result depends on its images, structure and the compression process.
    Can compression change image quality?
    Yes. Review diagrams, small print and photographs after compression.
    What if the compressed PDF is not smaller?
    Some files already use efficient compression. Keep the original if the result does not suit your needs.
    Where does Compress PDF process my file?
    Compress PDF uploads the input to the server for processing. Conversion results are stored for re-download until deleted; the memory cleanup timer does not delete stored results. See the Privacy Policy for current retention details.
