Frequently Asked Questions
How do I merge PDF files online for free?▾
Click "Add Files" or drag and drop your PDFs. Reorder them by dragging, then click Merge. The combined PDF downloads instantly. No file limits, no signup, no watermarks.
Are my PDF files uploaded to a server?▾
No. All merging happens entirely in your browser using JavaScript. Your files never leave your device.
Is there a file size or page limit?▾
There is no artificial limit. The tool processes files in your browser, so very large files (100MB+) may be slow depending on your device memory.
Can I reorder pages before merging?▾
Yes. After adding files, drag and drop them to change the order. The final PDF will follow the order shown on screen.
