Free PDF Compressor
Shrink any PDF file for free. No upload, no watermarks, no hidden limits. Just open, compress, download — all inside your browser.
No account needed · zero uploads, verifiable in DevTools
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's free tier gives you the full compression engine — the same one Pro users get — just capped at 5 uses per day rather than unlimited.
Open the file, drag the quality slider, download — no registration screen in between, and no watermark stamped across your compressed PDF.
