How much smaller will my file be?

It depends on the contents. A document of plain text will barely change, while one full of photographs can lose most of its size.

Will the text become blurry?

No. Only images are recompressed. A scanned page counts as an image, so treat a scan accordingly.

Which level should I choose?

The lightest reorganises the file and leaves the images alone. The strongest re-encodes photographs and gives much the largest saving.

Yes. Step back and try a different level.

Compress a PDF

Reduce the size of a PDF at one of three levels. Text stays sharp at every level; it is the images inside the file that are recompressed, and you can compare the results on screen before you commit to one.
