How it works
Upload a PDF → pick an output quality → hit Start. The engine re-samples each page and rebuilds a smaller PDF you can download instantly.
Great for email attachments, upload limits and archiving. Scanned or image-heavy PDFs usually shrink the most; text-only vector PDFs have less room to spare.
