About Merge PDF
Merging is the quickest way to turn a pile of separate scans into one file — useful when a form asks for a single PDF containing your ID, address proof and photograph.
Add the PDFs in the order you want them to appear. Each file shows its page count so you can check you picked the right document before merging.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Everything is processed by your own browser, so the practical limit is your device's memory.
Are my files uploaded to a server?
No. The merge happens inside this page using your browser, so your documents never leave your device.
Will the quality change?
No. Pages are copied across exactly as they are, so text stays selectable and images are untouched.
