    Good to know

    • Compression works by rendering each page to an optimized JPEG image and rebuilding the PDF, which is most effective on scanned and image-heavy files.
    • Because pages are flattened to images, selectable text becomes non-selectable — use the merge tool instead if you must keep text searchable.
    • Typical size reductions range from 40% to 80% depending on how image-heavy the original PDF is.

    Frequently asked questions

    How do I compress a PDF?

    Add your PDF above and click Convert. Your browser rebuilds it at a smaller size and downloads the result.

    Will the text still be selectable?

    No. This method flattens pages to images to shrink them, so text is no longer selectable. If you need searchable text, avoid compressing.

    How much smaller will my PDF be?

    It depends on the content — scanned and photo-heavy PDFs shrink the most, often by 40–80%.
