Compression
Pages are saved as images, so text can no longer be selected or searched. This works best for scanned documents.

Frequently asked questions
- How does the compression work?
- Each page is redrawn as a JPEG image at a lower resolution. Scanned documents shrink a lot this way.
- Will I still be able to select text?
- No. After compression each page is an image. Keep the original if you need searchable text.
- The file did not get smaller. Why?
- PDFs that are mostly text are already small. The tool tells you when compression would not help and keeps the original.
