Separate scans
Scanners and phone apps usually produce one PDF per page. Put the sheets back in order and get the whole document as a single file.
Merge PDF online
nothing leaves your device
Combine several PDF documents into a single file, in the order you choose. Everything happens inside this browser tab: the files are never sent to a server, and we never see them.

When merging a PDF is the right fix
Documents arrive in pieces more often than they should: the scanner writes one file per sheet, the contract comes separately from its annex, every chapter of the report arrives from a different person. Putting it all into one file makes it easier to send, file and print.
Email attachments
Instead of attaching six files and hoping nobody opens them out of order, send one document with everything in the sequence you set.
Reports and proposals
Cover, body, annexes and exported spreadsheets become one continuous document, ready to file, print or submit.
How to merge PDF files
- 1
Choose the files
Drop your PDFs anywhere on this page, or use the button to select them. You can add more files later without starting over.
- 2
Set the order
Use the arrows to move each file up or down. The list shows how many pages each one has, so you can check before merging.
- 3
Download the single PDF
Click merge and download the result. The file is assembled in your browser and goes straight to your downloads folder.
What this tool does differently
Nothing is uploaded
The best-known services send your file to a server. Here the PDF is read and rebuilt in the tab’s memory — you can verify it in your browser’s network panel.
No queue, no waiting
With no upload and no download of the result, merging a few documents takes as long as processing the bytes: usually under a second.
No watermark
The final file gets no stamp, no footer and no advertising page. It is your document, exactly as you assembled it.
Order under control
You reorder the files before merging and see each one’s page count, instead of discovering the mistake after downloading.
No file limit
There is no cap of two or three documents at a time, and no daily operation counter. The limit is your computer’s memory.
Content preserved
Text stays selectable, links stay clickable and fonts travel with the file. Nothing is flattened into an image along the way.
Why your documents stay with you
Contracts, payslips, medical reports, tax returns. Most of what people merge into a PDF is exactly what they would rather not upload to an unknown server. This tool was built so that trade-off does not have to be made.
Local processing
Reading and writing the PDF happens in JavaScript, inside the tab. No byte of the document travels over the network.
No storage
There is no server keeping a copy, because there is no upload. Close the tab and the file leaves memory.
No account
No sign-up, no email, no daily limit tied to a login. You open the page and use it.
Frequently asked questions
Are my files uploaded to a server?
No. The PDF is processed entirely in your browser with JavaScript. You can confirm it by opening the browser network panel (F12) before merging: no request carrying the document is made.
Is there a limit on size or number of files?
Each file can be up to 100 MB, and there is no limit on how many. The real constraint is the memory available on your computer — merging dozens of large documents can get slow on older machines.
Does the document quality change?
No. Pages are copied as they are, with fonts, images and annotations intact. There is no recompression and no conversion to image, so the text stays selectable and searchable.
Does it work with password-protected PDFs?
No. An encrypted PDF has to be opened with its password before any edit, and this tool tells you when it finds one. Remove the protection in the program that applied it and try again.
Can I change the order after choosing the files?
Yes. The list shows each file with its page count, and the arrows move items up and down. The final order is exactly what is on screen when you click merge.
Do I need to install anything?
No. The tool runs in any current browser, on desktop or phone. There is no extension, no program and no sign-up.
