Frequently Asked Questions

Completely secure. The cornerstone of ContinuePDF is total privacy. Every operation runs locally within your browser environment. Documents remain on your computer exclusively - no server transfers ever occur. Nobody, including us, can access your files.

Totally free with zero catches. No surprise charges, subscription requirements, usage restrictions, or locked features. Every tool is fully available at no cost because document processing should be universally accessible.

Once initially loaded, the majority of tools function entirely offline! Processing libraries cache in your browser, allowing you to work without internet - merge, split, compress, and modify PDFs disconnected. Only specialized features requiring external resources (like converting web-based content) need connectivity.

Zero restrictions on file sizes, quantity, or usage frequency. We don't throttle or limit anything artificially. Your computer's RAM and processor are the only constraints - extremely large documents might process more slowly depending on your hardware.

Failures are rare but can happen for a few reasons:

• The PDF might be corrupted or not compliant with standard specifications.
• The file could be encrypted with a password you don't have. Please use our Decrypt tool first.
• The file might be a special "XFA" or dynamic form-based PDF, which some of our tools cannot process.

Privacy-conscious tracking only. We utilize Google Analytics for anonymous visitor metrics and site improvements. No personal data collection occurs - we monitor general usage patterns while your identity and documents remain completely private.

Powered by cutting-edge web standards and technologies. Core functionality relies on JavaScript libraries including PDF-lib.js and PDFKit.js, optimized through WebAssembly for native-speed browser execution.
