Question 1

Is there a limit to how many PDFs I can merge?

Accepted Answer

No. You can merge as many PDF files as you like. The only limit is your browser's available memory.

Question 2

Will the merged PDF preserve the original quality?

Accepted Answer

Yes. Merging combines the PDFs at the document level without re-encoding or re-rendering pages, so quality is fully preserved.

Question 3

Can I reorder the files before merging?

Accepted Answer

Yes. After uploading, you can drag to reorder files or use the up/down arrows to set the exact order.

Question 4

Are my files sent to a server?

Accepted Answer

No. All merging happens in your browser using JavaScript. Your files never leave your device.

Question 5

What file size can I merge?

Accepted Answer

There is no hard limit — it depends on your device's memory. Most modern browsers handle several hundred MB without issues.
