FAQ

Good to know

Most of a PDF's size comes from the photos and scans inside it. A PDF that is mostly text, or whose images are already small and well compressed, has little left to remove, so the tool tells you instead of handing you a bigger file. Try Strong for image-heavy PDFs. Some image types, such as CMYK print images and black-and-white scans, are kept as they are.

Yes. Only the images are re-saved. Text, fonts and vector graphics are left exactly as they are, so they stay crisp at any zoom and you can still select, search and copy the text.

No. The tool runs inside this browser tab. Your input is processed in memory on your device and is gone when you close the tab.
