Universal Local Compressor – Private PDF & Image Optimizer (Runs 100% in Your Browser) - Witty University
university.witty.computer
A sleek, privacy-first PDF & image compression tool that runs entirely in the browser — no uploads, no tracking, no servers. Perfect for creators, students, and developers who need fast, local file optimization.  Purchase once, use forever. https://www.youtube.com/shorts/UWfrQS97S3M

Every time you upload a PDF or image to a random “free” compression site, you’re handing over the full file (sometimes including hidden metadata like GPS location, device info, and embedded text) plus your IP address and usage data.

You have no idea how long it’s stored, logged, or reused. 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.

    Also this way you can use the same tool across desktop and mobile
