🚀 Open Merge PDF Files Online

100% free · no upload · no account · works offline

Drag & drop multiple PDFs, reorder them, and merge in seconds. Because processing happens in your browser, your documents never leave your device — ideal for contracts, invoices and legal files.

🔒 Privacy first: this tool runs entirely in your browser (open-source PDF.js engine). Your file is read locally, processed in memory, and never transmitted. Disconnect Wi-Fi and try it — it still works.
