No limits, no payment, ever
Select the PDF that is too large for the upload limit.
Choose Scanned / Image-heavy for scans and photos (biggest saving), or Text Document to keep text selectable.
Medium suits most portals. Use Low or Minimum if you need a very small file; lower the render scale for extra saving.
Compare original and new size, preview the pages, then download.
Compress PDF shrinks PDFs for portals with strict limits such as 200 KB, 500 KB or 1 MB, while keeping them readable.
Scanned PDFs often shrink by 60–90% in Scanned/Image mode. Text PDFs shrink less because they are already efficient.
Scanned/Image mode turns each page into a picture. Use Text Document mode if you need selectable text.
Use Scanned mode, Low or Minimum quality and a render scale around 70–80%. Also remove unnecessary pages with Delete PDF Pages.
