Upload a PDF, pick a compression level, and download a smaller version — works best on scanned or image-heavy PDFs.
Upload your PDF, choose a compression level, and click "Compress & Download". Each page is re-rendered at the chosen quality and rebuilt into a new, smaller PDF.
This method works best on scanned documents or PDFs full of photos — it re-encodes each page as an optimized image. Text-heavy PDFs (like a Word export) may not shrink much, since text is already very compact.
No — this method converts each page into an image to reduce size, similar to most free online PDF compressors. If you need to keep selectable text, avoid the "Max compression" setting or consider not compressing purely text-based PDFs.
If your PDF is mostly text, it's likely already small and efficiently encoded — image-based compression has little to improve on. This tool helps most with scanned pages or photo-heavy PDFs.
No — compression happens entirely in your browser using your device's processing power.
