Compress a PDF to 100 KB (or as small as possible)

Many forms and portals cap uploads at 100 KB. This tool uses the strongest compression by default. We can't promise an exact size, since results depend on your file, but image-heavy PDFs often drop a lot.

    How to use Compress PDF to 100KB

    1. Upload your PDF.
    2. Keep High compression selected.
    3. Compress, then check the new size. If it's still too big, remove pages you don't need and try again.

    Frequently asked questions

    Will my PDF end up under 100 KB?

    Not always. Text-only PDFs and very long documents may stay above it. Scans of a few pages usually get much closer.

    What if it's still too large?

    Keep only the pages you need, or re-scan at a lower resolution, then compress again.
