Does compression lower the quality?
No. This tool re-saves the PDF structure efficiently without touching the images or text quality inside it — nothing is downscaled or blurred.
Are my PDFs uploaded anywhere?
No. Your files are processed in your browser only — they are never uploaded to any server.

Yes — 100% free, no sign-up, no watermark on the compressed PDF.
