How to merge PDF files

Merging PDF files combines two or more PDFs into a single document in the order you choose. You add the files, arrange them, optionally pick page ranges, and export one merged PDF — entirely in your browser.

Add two or more PDFs with Add PDFs or Choose PDF.
Drag the file cards, or use Move earlier / Move later, to set the final order.
Open a file's options to include only specific page ranges, if needed.
Choose Merge PDFs, then download the combined file.

Frequently asked questions

Can I choose the order of the files?

Yes. Drag the cards or use the move buttons; the merged PDF follows the on-screen order, top to bottom.

Can I merge only some pages from a file?

Yes. Open a file's options and set a page range before merging.

Is there a limit to how many PDFs I can merge?

There is no fixed limit; very large jobs depend on your device memory, since everything runs locally.
