Frequently Asked Questions

What file formats can I merge?

Our text merger supports various text formats including .txt, .md, .html, .css, .js, .json, .xml, .csv, and .rtf files. As long as the file contains text content, it can be merged.

How many files can I merge at once?

You can merge multiple files at once. The exact limit depends on your device's available memory and browser limitations, but you can typically merge dozens of files without issues.

Can I change the order of files before merging?

Yes! Our drag-and-drop interface allows you to easily reorder files before merging. Simply drag files to rearrange them in your preferred order.

What are merge modes?

Merge modes determine how content from different files is combined. Sequential mode keeps files in order, interleaved alternates content between files, and random mixes content randomly.

Can I add separators between files?

Yes, you can choose from various predefined separators like double newlines, horizontal rules, or create your own custom separators to clearly distinguish between different files.

Is my data private?

Yes, absolutely. All merging happens in your browser using JavaScript. Your files never leave your device or get sent to any server.
