Frequently Asked Questions

Yes, completely free. No sign-up, no limits, no hidden charges.
It depends on the compression level you choose. Low compression keeps quality very high with a smaller reduction. High compression gives the smallest file size with a slight quality reduction. Note that image-based compression flattens each page into a picture — if your PDF has selectable text, we'll ask whether you'd rather keep the text intact instead.
Absolutely. Your files never leave your device. All processing happens locally in your browser.
Some PDFs are already efficiently packed, or don't shrink further with the method used. In that case the tool keeps your original file rather than replacing it with a larger one.
Yes, the tool works on any device including smartphones and tablets.
