PDFs that are mostly text or already optimized have little to compress. Image-heavy PDFs usually shrink the most.

Yes. Every tool on the site is completely free, with no sign-up, watermarks or hidden limits beyond the per-file size limit.

Files are processed on our server only for as long as needed. Inputs are deleted as soon as processing finishes, and the result is deleted shortly after you download it — or automatically after a short time if you don't. We never keep copies.
