No — merging happens locally in your browser using JavaScript. Your PDF files are never uploaded to a server, so this works even with sensitive documents.
FAQ
- Is there a file size limit?
- Since everything runs in your browser, the practical limit depends on your device's memory rather than a fixed cap. Very large files may take longer to process.
- Will the page order change?
- No — pages keep their original order within each file. The order you set for the files determines the order they appear in the merged document.
