Optimization Tips

For the best results when merging PDFs, ensure your source files are already optimized and properly formatted. Remove any unnecessary pages before merging to keep your final file size manageable. If you're merging many large files, consider compressing them first using our Compress PDF tool. When arranging files, think about the logical flow of information – for example, place cover pages first, main content in the middle, and appendices at the end. For very large projects with dozens of files, it may be more efficient to merge them in groups first, then combine the groups. This approach also makes it easier to reorganize sections if needed.

Privacy & Security

Your privacy and security are our top priorities. All file uploads and processing are done over secure HTTPS connections with TLS encryption. Our servers process your files in isolated environments, and we automatically delete all files within one hour of processing – usually much sooner. We don't track, analyze, or store any information about the content of your PDFs. No registration means no email addresses, no user profiles, and no personal data collection. Our infrastructure is designed with security best practices, including regular security audits and compliance with data protection regulations. You can merge sensitive documents with confidence, knowing your information remains private and secure.

Pro Tip

Pro tip: Before merging, use descriptive filenames for your source PDFs. This helps you keep track of which documents are included and makes it easier to recreate the merged file if needed later. Consider creating a naming convention like '01_Introduction.pdf', '02_Chapter1.pdf', etc.
