Terms and Disclaimer

Last updated: October 18, 2026

Using the tool

Compress PDF Doc is free for personal and commercial use. You keep all rights to your documents. Because files never leave your device, you are responsible for downloading your results and keeping your originals.

Important limitations

Compression rewrites the PDF. Digital signatures become invalid after any change, so compress before signing. Recommended and Extreme remove accessibility tags by default; choose High quality if your document must stay accessible. Password-protected PDFs are not modified.

No warranty

The tool is provided “as is”, without warranties of any kind. Results vary by document, browser and device, and we are not liable for lost files or any damages arising from use of the site.

Third-party software

The compressor uses open-source components including pdf-lib (MIT), PDF.js (Apache-2.0), MozJPEG compiled to WebAssembly (IJG, BSD-3-Clause and Zlib licenses) and fflate (MIT). Full license texts ship with the tool.

We may update these terms. Continued use of the site means you accept the current version. Contact: contact@compresspdfdoc.com.
