Merge PDF files into one document
Free PDF merging lets you combine multiple documents into a single file in seconds. Upload any number of files, arrange them with the arrows, and download the finished document — no login, no limits, no watermark.
Full privacy — files processed locally
Unlike many online services, your documents here are never sent to a server. All processing happens in your browser on your device, so confidential contracts, invoices, or scans stay with you alone.
Frequently asked questions
- Are my PDF files sent to a server?
- No. Merging happens entirely in your browser. Documents never leave your device and are never sent to any server.
- How do I set the order of the merged files?
- After uploading, use the ▲▼ arrows next to each entry to arrange them in the desired order. Pages will be merged exactly in the order shown in the list.
- How many files can I merge at once?
- There is no limit on the number of files or pages. It depends on your device's memory — very large documents may take longer to process.
