Merge PDF Documents

Whether you're combining reports for a presentation, assembling application materials, or compiling research papers, merging multiple PDF documents into a single file is one of the most common document tasks. Many routes add upload steps or account friction before the first merge. Coda One keeps the first task more direct.

Our PDF Merger runs in your browser. When you drop files into the tool, they're processed with pdf-lib, an open-source JavaScript library. The merged document is generated in the same browser session and downloaded directly. File content is not uploaded to our servers during merging.

The tool handles standard PDF documents from many sources: scanned documents, digitally created files, exported spreadsheets, converted images, and more. Add the files you need, drag to reorder, remove any you do not want, and merge when ready. The process is usually quick for typical document sets and works across modern desktop and mobile browsers, so you can start the first merge directly from the page.
