Can I control the order of files?
▼
Yes, use the up/down arrows to drag files into your preferred order before merging.
What separators can I use between files?
▼
New line, double new line, horizontal rule (---), section break (===), no separator, or a custom separator you define.
Can I add filename headers?
▼
Yes, check 'Add filename header before each file' to insert a comment with the filename before each file's content.
Is there a file size limit?
▼
There's no hard limit, but very large files (100MB+) may be slow to process in the browser. For most use cases it works instantly.
