Compress PDF

Shrink a PDF that is too big to email or upload, right inside your browser. Load a file and the tool rebuilds it with object streams and cleaned up structure, which strips redundant data and can reduce the size of many documents. It then shows you the original size next to the new size and the percentage saved so you can see exactly what you gained before downloading. This works best on PDFs that carry structural bloat or duplicated resources; note that browser-side compression cannot re-encode already compressed images the way heavy desktop software does, so the savings depend on the file. Everything happens locally with a PDF library loaded in the page, so your document is never sent anywhere and the process is quick. Your original file stays untouched, and you can try it on any PDF to see if it helps.
