Compress PDF Lossless
Compress a PDF losslessly so text and vectors stay perfect. Smart re-encode only for scanned images.
Why it matters: Lossless copy keeps text and vectors perfect; only scanned images are re-encoded, and the tool never returns a bigger file.
How to Compress PDF Lossless
- Open the Compress PDF Lossless tool and add your PDF (drag-and-drop or browse — it never leaves your device).
- Pick a level: Best quality (sharpest), Balanced (default), Smaller file, or Tiny (aggressive re-encode).
- Click Compress PDF. Pages are re-rendered as optimized images, so the lighter file downloads instantly.
- Download the result — everything runs in your browser, nothing is stored or sent.
