PDF Merger
Combine several PDF files into one document without installing software or uploading anything. Add your PDFs, put them in the right order by dragging them or using the arrow buttons, name the output file, and download a single merged PDF. Text, images, and page layouts are copied as they are, and everything runs in your browser, so contracts, invoices, and other private documents never leave your device. No signup and no watermark.
Operational Workflow
Follow these standard protocols to process your files safely.
Click the upload area or drag and drop your PDF files. You can select several files at once and add more later.
Check the list. Each file shows its page count and size. Drag files or use the arrow buttons to put them in the order you want, and remove any you do not need.
Type a name for the merged file if you do not want the default.
Click Merge & download. The tool combines the files on your device and saves the merged PDF.
To start another merge, click Clear all and add a new set of files.
