No. The PDF is read, re-drawn and rebuilt entirely in this browser tab using JavaScript libraries. Nothing is sent to any server — safe for private documents.
That happens with PDFs that are already efficiently made — for example a short text document exported by Word. Re-drawing its pages as photos can outweigh the original. The tool tells you honestly when nothing was saved, and your original file is never touched.
Yes — same pages, same order, same page sizes. At Balanced and High quality, scans stay sharp and readable. Photos inside pages are stored as JPEG, exactly like most scanned PDFs already are.
Up to 60 pages at a time, which covers most documents. Very large scans can take a little while on older phones — the progress bar shows how far along it is.
Compression happens locally in this browser tab. Your PDF is never uploaded, and no copy is kept anywhere — close the tab and nothing remains.
