Make a large PDF small enough for email and upload limits on government and HR portals. Choose between the smallest file and the best quality, or keep the text selectable, and see the size before and after.
Balanced suits most files. Use Strong when a portal has a strict size limit, and Light when the document must stay very sharp.
Strong, Balanced and Light save each page as an optimized image to reach small sizes. Choose Keep text instead: it shrinks only the photos inside the PDF, so text stays selectable and searchable.
Some PDFs are already compressed. The tool tells you, and doesn't offer a bigger file.
Everything happens in your browser. Your files are never uploaded to a server, so nobody else can see them.
