Frequently Asked Questions

How many PDFs can I merge at once?+
There is no fixed limit. You can merge as many PDF files as your browser's memory allows. For very large batches, we recommend merging in groups.
Can I reorder files before merging?+
Yes. After adding files, drag and drop them to arrange the order. The merged PDF will follow the order you set.
Are my files uploaded to a server when merging?+
No. All merging happens directly in your browser. Your PDF files are never uploaded to any server — they stay on your device throughout the entire process.
Can I merge PDFs on my phone?+
Yes. The merge tool works on mobile browsers. Add files, reorder them, and download the merged result — all on your phone or tablet.
