Troubleshooting
The pages came out in the wrong order.
Files merge top-to-bottom in the list, not by filename. Reorder with the arrows before running.
Frequently asked
Are my files uploaded?
No. Merging happens entirely in your browser using WebAssembly — nothing is sent to a server.
Is there a file limit?
The free tier merges generously sized files. Very large sets are smoother on Pro.
