Common questions

How does PDF compression work here?: Your browser redraws each page as an image and builds a new PDF at the quality level you choose. We then show the real file size before and after — not an estimate.
Will every PDF get smaller?: No. Files that are already small or well-optimised may barely shrink, or may not shrink at all. If that happens, we will tell you honestly.
What is the maximum file size?: 50 MB for this version. The limit is shown before you choose a file so you can see it up front.
Do you upload my PDF to compress it?: No. Your PDFs and images are processed in your browser and are not uploaded to our servers. Keep your original file and check the downloaded result.
