How to Merge PDF Files

Three steps, all in your browser.

1

Add your PDFs

Drag in two or more PDFs, or click the box to browse and select several at once. Each file stays on your device and is read locally — nothing is uploaded.

2

Put them in order

Use the up and down arrows next to each file to arrange them in the order you want them to appear, or remove any file you don't need with the × button.

3

Merge and download

Click Merge PDFs to combine every page from every file, in list order, into one PDF, then download the result. Need to pull pages back apart instead? Use Split PDF.

Frequently Asked Questions

What order are the PDFs merged in?
Whatever order they appear in the list. Files are added in the order you pick or drop them, and you can move any file up or down before merging — the final PDF's pages follow that same top-to-bottom list order, file by file.
Are my PDFs uploaded anywhere?
No. Each PDF is read on your own device and the merge happens entirely in your browser using a client-side PDF library. Nothing is uploaded, logged or stored, so it is safe for private or sensitive documents, and closing the tab clears everything.
Does the merged PDF include every page from every file?
Yes. Every page of every file in the list is copied into the merged PDF in full — nothing is skipped or dropped. The resulting page count is simply the sum of each source file's page count, in the order the files are listed.
Can I remove a file before merging?
Yes. Click the remove button next to any file in the list to take it out before you merge. The remaining files keep their relative order, and you can re-add a file at any time by dropping or browsing for it again.
