Browser-based tool

Merge PDF

Combine multiple PDF files into one document and change the file order before merging.

🧩

Choose PDF files

Select two or more PDFs, then arrange their order

Use the arrows beside each file to set the final order. The tool copies pages into a new PDF without intentionally rasterizing them.

Can I change the order?

Yes. Use the arrow controls.

How many files can I merge?

The practical limit depends on browser memory.
