About this tool
Email services and online forms often limit attachment size. This tool shrinks scanned and image-heavy PDFs by re-encoding each page as an optimised image. Text-only PDFs are usually small already and may not shrink much.

Questions and answers
Why can I not select text after compressing?
To reduce size, pages are converted to images. This works best for scanned documents but removes selectable text.
Why did my file not get smaller?
PDFs that are already small or text-only may not benefit. In that case the tool tells you and does not save a larger file.
