Managing multiple PDF documents can be a hassle, especially when you need to send them as a single file via email or upload them to a portal. Xizoa Hub's PDF Merger is the ultimate solution. We provide a seamless, secure, and lightning-fast way to combine multiple PDF files into one—completely for free.
Whether you are a student submitting assignments, a business professional combining reports, or just someone trying to organize personal receipts, our tool simplifies the process. No need to install heavy software like Adobe Acrobat; just open your browser and start merging.
Why Choose Xizoa PDF Merger?
There are many tools out there, but here is why Xizoa is the preferred choice for thousands of users:

2. Unlimited Merging
Combine 2, 10, or even 50 files at once. We do not impose hidden limits on the number of files or the file size. Merge as much as you need.
3. Drag & Drop Simplicity
Our user interface is designed for speed. Simply drag your files onto the box, reorder them if needed (coming soon), and click merge. It takes less than 5 seconds.
4. Works on All Devices
