Do keep in mind that uploading and compressing PDFs can take some time, after hitting "upload & shrink" hang around until the page re-loads.
Start by uploading your file. The progress bar indicates approximate upload progress, but compression takes longer so please be patient! The site is still processing things in the background even if you don't see any changes!
When you upload a file to us, we run through all of the content and try to recude the sizes of images, optimise the PDF for screens and reduce the colour pallet slightly.
People who use our service see up to 40% reduction in file size!
