Frequently asked questions
Will compressing reduce PDF quality?
Higher compression trades a small amount of visual quality for a much smaller file. Medium is a good default for most documents; use Low compression for documents where crisp detail matters.
Does this work on scanned documents?
Yes — the compressor works especially well on image-heavy and scanned PDFs, since most of the size reduction comes from re-encoding embedded images.
Is PDF Compressor free to use?
Yes, PDF Compressor is free for everyday use with standard limits. Premium plans remove file size limits and ads, and unlock batch processing.
Is it safe to use this tool with my files?
Yes. Files processed with PDF Compressor are handled securely, and uploaded files are automatically deleted from our servers after a short retention window (1 hour for free accounts, 24 hours for premium accounts). Many operations run entirely in your browser, so the file never leaves your device.
