Frequently Asked Questions
Is it safe to merge PDFs online?
Yes. This tool runs entirely in your browser using JavaScript. Your files are never uploaded to any server — all processing happens locally on your device.
How many PDFs can I merge at once?
You can merge up to 50 PDF files in a single operation. There is no file size limit beyond what your browser can handle.
Can I reorder the PDFs before merging?
Yes. After uploading, drag and drop files in the list to rearrange them in your preferred order before merging.
Does merging PDFs reduce quality?
No. The merge process copies pages exactly as they are. Text, images, and formatting are preserved without any quality loss.
