How to use
Add text files and use move up and move down to adjust the order.

Frequently asked questions
Will the merge automatically clean up the original line breaks or remove the BOM?
No. Separators are additionally added, and existing characters are retained; the system clipboard may adjust line wrapping, so please export TXT if precise bytes are required.
The file name and content are only processed in your browser and are not transmitted to the server. The original file will not be overwritten. Please export the required results before leaving the tool.
