Merge PDF files
Combine two or more PDFs into a single document. Drag to set the order, then download the merged file. Everything happens in your browser, so your documents are never uploaded anywhere.
100% private: files are processed in your browser and never uploaded to any server.
How it works
- Drop two or more PDF files into the box above, or click to choose them.
- Drag the files into the order you want them to appear in the final document.
- Click “Merge PDFs” and download the combined file.
Frequently asked questions
Is there a limit on the number or size of PDFs I can merge?
No. Because merging happens on your device, there are no queues, no daily limits and no maximum file size beyond what your browser can handle.
Are my PDFs uploaded to a server?
No. Pdfect merges PDFs with code that runs inside your browser. Your files never leave your device — you can even disconnect from the internet after the page loads and the tool keeps working.
Will the merged PDF keep the original quality?
Yes. Pages are copied into the new document as-is — text, images and vector graphics are not recompressed or altered.
Can I change the order of the files before merging?
Yes. After adding your files, drag them (or use the arrow buttons) to arrange them in any order. The merged PDF follows the order shown in the list.
