Drop PDFs to merge
or
Combine PDFs without uploads
Drag in your documents, arrange them in the order you want, and create a single PDF without sending anything to a server. GoPDFConverter merges files directly in your browser using open-source libraries, so sensitive documents never leave your device.
Tip: You can add more files at any time with the Add More Files button, or switch to split/compress/rotate after previewing the merged result.
Why it’s private
All processing happens locally — no uploads, logins, or watermarks.
- PDF merging powered by the open-source PDF-LIB library.
- Works offline once loaded thanks to the optional Service Worker.
- Compatible with large files; performance depends on your device only.
