FAQ
Is there a file size limit?
Processing is local, so the limit is your device memory. Most laptops handle hundreds of pages easily.
Can I reorder files before merging?
Yes, drag files into the order you want — the merged PDF follows it.
Are my documents private?
Completely. PDFs are merged inside your browser and never uploaded.
