COMMON QUESTIONS

Frequently Asked Questions

Combine & stack document rules explained
? How does the PDF merging tool work?
It reads the object streams from each uploaded PDF, combines their page arrays, structures new cross-reference tables, and compiles the merged document.
? Will my confidential PDFs be sent to online servers?
Absolutely not. The parser parses, splits, and re-assembles the PDF streams locally inside your browser thread. No file uploads occur.
? Can I merge password-protected PDFs?
You will need to enter the user password for each protected PDF file to unlock its pages before the merger tool can combine them.
? Is there a limit on the number of PDFs I can combine?
There is no hard software limit. You can combine dozens of files, subject to your web browser's memory capacity.
? Does merging PDFs reduce the quality of embedded images?
No. The tool copies the original raw data streams directly without decoding or re-compressing images, preserving layout quality.
? Are hyperlinks and bookmarks preserved in the merged PDF?
Yes, standard internal page links and external URL hyperlinks are preserved in the final output file.
