How we handle your data

Compress PDF

Make a PDF smaller by recompressing its embedded photos and scans. Text, forms and layout are kept. Documents that are mostly text may not get smaller; signed or encrypted PDFs are refused.

Three A4 pages, each with a line of text and a large synthetic photo. Standard should shrink it by more than half and keep 3 pages of text; Strong is smaller still.

A practical guide

Compress PDF: a worked example

  1. Choose one PDF of up to 60 MB and 200 pages.
  2. Choose Standard, or Strong for smaller files with softer images.
  3. Compress and compare the sizes; if the PDF is already compact, no copy is made.

Try this example

Compress the three-page photo sample with Standard: it should shrink by more than half and keep its three pages of text. Strong makes it smaller still with softer photos. A text-only PDF may show that no smaller copy was made.

Before

  • Report with photos

After
