Questions
Is Compress PDF free in PDFMoose?
Yes. It is free in PDFMoose, with no account, no watermark and no daily task limit.
Are my files uploaded when I compress a PDF?
No. The work happens entirely in your browser, so your file stays on your device and is never uploaded.
How much smaller will my PDF get?
It depends on the file. PDFs full of large images shrink most, and lower image quality gives a smaller file but softer pictures.
