A file merger concatenates multiple files into one output. For text formats (TXT, CSV, JSON, HTML, Markdown, code), the tool joins raw content in the order you choose, with an optional separator between segments.
Unlike a ZIP archive (which bundles files), a merger produces one readable file you can share, archive, or import—ideal for logs, exports, notes, and stitched documentation.
Client-side mergers like SnapToolsOnline read files with the browser File API and assemble the result in memory—no upload queue and no server copy of your data.
