KyaToolsJi is a premium, high-performance document management platform designed to simplify your digital life. Our **Merge PDF** tool allows you to combine separate PDF files into a single, cohesive document without compromising quality.
We built KyaToolsJi for professionals who demand speed and precision. Unlike basic tools, we support advanced features like **reverse page ordering** (ideal for scanned documents), **file duplication**, and **separator page injection**—features typically found only in paid desktop software.
Combine quarterly reports, financial spreadsheets, and presentation slides into one professional executive summary package.
Merge your thesis chapters, bibliography, and cover sheet into a final submission file. Use separator pages to keep sections distinct.
Compile contracts, evidence scans, and witness statements. Use our reverse-order feature to fix scans that were fed backwards.

Yes, KyaToolsJi is 100% free. We believe in providing premium tools without paywalls. You can merge unlimited files with no watermarks.
Security is our foundation. We use SSL encryption for data transfer, and our servers operate with strict auto-deletion policies. Your files are wiped permanently after one hour.
We offer a unique feature for this. In the page range box for any file, simply type the range backwards (e.g., "10-1"). Our engine will automatically reverse those pages in the final output.
Yes! Just click the "Duplicate" icon next to any file in the list. This creates a perfect copy in the merge queue, allowing you to include the same document multiple times.
Absolutely. Check the "Add Separator Page" option before merging. This automatically inserts a blank sheet between every file, which is ideal for double-sided printing.
No. We use advanced "stream copy" technology. We don't re-compress your images or text; we simply restructure the file container, ensuring 100% original quality.
Yes, our interface is fully responsive. You can combine PDF files directly from your iPhone, Android, or tablet browser with the same speed and ease as on a desktop.
We support extensive file sizes suitable for all standard documents. Our efficient processing engine handles large files smoothly.
No account is required. You can start using the tool immediately. We value your time and anonymity.
