How to Merge PDF Files Online
Upload two or more PDF files by dragging them into the upload area or clicking to browse. Reorder them using the arrow buttons to set the page order in the final document. Click Merge to combine them into a single PDF. The entire process runs in your browser using the pdf-lib library — your files are never uploaded to any server.
Why Use Our PDF Merger?
Unlike most online PDF mergers that upload your files to remote servers, ours processes everything locally in your browser. This means complete privacy for sensitive documents, no file size limits imposed by server uploads, and instant results regardless of your internet speed. It's completely free with no watermarks or signup required.
Frequently Asked Questions
Are my files uploaded to a server? No. All merging happens in your browser using JavaScript. Your files never leave your device.
Is there a file size limit?There is no server limit since processing is local. Very large files (50MB+) may be slow depending on your device's memory.
Can I reorder the pages? Yes. Use the up/down arrows next to each file to change the order before merging. The pages appear in the order shown.
