How to merge PDF files into one
- Open the Merge tool and add two or more PDFs.
- Drag the files into the order you want them combined.

- Merge & Save to download the single combined PDF.

- Add as many PDFs as you need, in any order.

- Bookmarks and page sizes from each source are preserved.
- Runs entirely in the browser — no queue, no upload, no waiting.
When you would use it
One file for an application
Passport scan, certificates and a covering letter combined in the order a form asks for them.
Rebuild a document that arrived in pieces
Chapters or signed pages emailed separately become a single, properly ordered PDF.
Combine without a queue
No upload, no waiting for a server, no download link that expires in an hour.
Why it stays on your device
Most online PDF sites upload your document to a server, process it there and email you a link. This one does not. The PDF is opened, changed and saved by your own browser, so a contract, a bank statement or an ID scan never travels over the network — and the tool keeps working on a slow connection.
Questions
Are my documents uploaded to merge them?
No. The merge happens in your browser using your device's own memory, so the files never travel over the network.
Can I merge PDFs of different page sizes?
Yes. Each page keeps its original size and orientation in the combined file.
Is there a limit on how many PDFs I can combine?
There is no fixed count — the practical limit is your device's memory. Very large scans are the usual constraint, not the number of files.
Can I merge images into a PDF too?
Use the Create tool for that — it turns JPG, PNG and Word files into a PDF, which you can then merge here.
How do I merge PDFs without uploading them?
Add the files here and they are combined by your browser. Nothing is transmitted, which is why it also works offline once the page has loaded.
Can I merge PDFs in a specific order?
Yes — drag the files into the order you want before merging, and the preview shows exactly what the combined document will look like.
