How to use Merge PDF
- Choose or drag in the PDF files you want to combine.
- Drag the files into the order you want them joined.
- Press Merge PDFs and download your single combined file.
Combine files without sending them anywhere
Most online mergers upload your documents to a server before joining them. AllInOnePDF does the work inside your browser, so contracts, bank statements and school work stay on your own computer or phone. Pages keep their original quality, links and text, because the pages are copied as they are rather than re-printed.
Private by design
Merge PDF runs entirely in your browser. Your file is processed on your own device and is never uploaded to a server, there's no sign-up, and the result is ready to download as soon as it's done.
Questions
Is there a limit on how many PDFs I can merge?
There is no fixed limit. You can add as many files as your device's memory comfortably handles. Dozens of ordinary documents work fine on a phone or laptop.
Will merging reduce the quality of my PDF?
No. Pages are copied exactly as they are, so text stays sharp and searchable.
Can I change the order of the files?
Yes. Drag the rows, or use the up and down arrows, before you press Merge.
