Frequently Asked Questions
Q1: Is this PDF merger secure for business and personal documents?
A: Yes, it is highly secure. Our tool uses HTML5 file APIs and client-side JavaScript engine compiling. The entire merging process happens locally on your computer. None of your data or files are sent to any remote servers or external databases.
Q2: What is the maximum number of PDF files I can merge?
A: There is no set limit. You can merge as many documents as your browser's local RAM can support. This handles large documents of dozens of pages smoothly.
Q3: Will the output PDF have watermarks added to it?
A: No. Your combined PDF is saved as a clean, high-fidelity document without any watermarks, branding, or modifications.
Q4: Why did my file compilation fail?
A: Merging can fail if one or more of your uploaded PDF files are corrupted or password-protected. Ensure your documents are accessible and unprotected before attempting to merge them.
Q5: Can I run this tool offline?
A: Yes. Once the page loads, the PDF parsing engine is fully stored in your browser's cache. You can disconnect your internet completely and continue merging documents offline.
