Frequently asked questions
Does compressing a PDF reduce quality?
It can — compression works mainly by resampling the images inside the PDF. That's why this tool shows you a side-by-side preview of the first page at each level, so you can see the trade-off before downloading instead of guessing.
What is the best compression level?
Balanced (≈150 dpi images) is right for most uses: big savings with quality that still looks sharp on screen and in normal printing. Use Web (≈72 dpi) for email or web upload where size matters most, and Print (≈300 dpi) when it must print crisply.
How small can I make a PDF?
It depends on what's inside. Image-heavy PDFs often shrink by 70–90% on the Web preset. PDFs that are mostly text are already efficient and shrink less. The preview shows the exact resulting size for each preset before you download.
What happens to my file after compression?
It's uploaded over an encrypted connection, compressed, sent back to you, and immediately deleted from the server. Nothing is stored.
