Compression doesn’t require a server; it can run entirely in your browser. > > Witty University built a simple local HTML tool that compresses PDFs and images 100% offline, nothing gets uploaded: https://university.witty.computer/product/universal-local-compressor-private-pdf-image-optimizer-runs-100-in-your-browser/ > > Privacy is basic hygiene.
