Free PDF Compressor

Some "free" compressors add a watermark to the output or silently degrade quality below what you selected, nudging you toward a paid tier to get a clean result. PrivaPDF gives you the full compression engine for free, with no daily cap.
Open the file, drag the quality slider, download — no registration screen in between, and no watermark stamped across your compressed PDF.
