Reduce PDF file size while preserving quality
Nowhere. The entire compression happens in your browser using JavaScript — your PDF never touches our servers, never gets uploaded, never gets stored. Once you close the tab, the file is gone from memory; we have no copy. There is nothing for anyone to subpoena, breach, or sell.
Yes — no signup, no email required, no watermarks, no page limits, no daily quota, and no upsell for a paid tier. The tool runs entirely in your browser using free, open-source JavaScript libraries, so we have no server costs to recover. Your privacy IS the business model: we collect nothing because we have no use for it.
Scanned PDFs typically shrink 50–80% by recompressing embedded images and stripping unused metadata. Native text PDFs compress less (10–30%) because text is already efficient — most savings come from the images.
"Luleit is a lifesaver for legal docs. Knowing that my PDFs are processed entirely locally in the browser and never uploaded is a massive compliance win. No file leaks, no account needed, super fast."

"Outstanding speed and absolute privacy. I use it daily to compress medical records. Extremely secure and HIPAA compliant by design!"
Healthcare Administrator
"Unbelievably simple. No sign-up, no watermark, and the Chrome extension makes it a one-click launch from my browser toolbar. Best PDF utility out there."
