About this tool
Make a PDF smaller. Lossless mode rewrites the file efficiently without changing anything you see. Strong mode turns each page into a compressed image, which shrinks scans and image-heavy PDFs dramatically but makes text unselectable.

Frequently asked questions
Why did lossless mode save so little?
Most of a PDF's size is usually images. Strong mode re-compresses those, at the cost of selectable text.
Will the text still be searchable?
In lossless mode, yes. In strong mode, no; run OCR afterwards if you need searchable text.
