FAQ
How many files can I merge?
As many as you like, as long as the total stays under 200 MB.
Are my files uploaded?
No. Merging happens entirely in your browser; nothing is sent to a server.
What order are files merged in?
Files are combined in alphabetical order by filename for consistent output.
Can I add text between files?
Yes. Use a new line, a blank line or a fully custom separator.
Why do order and encoding matter when merging TXT files?
When merging text files, order decides whether the result makes sense: logs belong in chronological order and chapters in numerical order. This tool merges by filename, so with a consistent naming scheme (chapter-01.txt, chapter-02.txt, …) the output stays predictable and reproducible.
Encoding is the other classic pitfall: concatenating a GBK-encoded document with a UTF-8 file turns every non-ASCII character into mojibake. The tool detects UTF-8/GBK automatically and inserts a newline, blank line, or custom separator between files, so the last line of one file never glues onto the first line of the next.
Concatenate files and print on the standard output.
