📑 Merge PDF Files

Pick two or more PDF files, put them in the right order and download one combined PDF. Everything happens on your own device; nothing is uploaded.

PDF files You can add more files later; they are added to the end of the list.

Is it safe?

Yes, in the sense that matters most: the files never leave your computer. The page loads a PDF library into your browser and does the merging there, so there is no server that could keep a copy. You can even disconnect from the internet after the page has loaded and it still works.

What is kept

Pages are copied exactly, including text, images and links on the page. Bookmarks (the outline in the sidebar of some PDF readers) and form fields that span documents may not carry over, because they belong to the original file rather than to a page.

Limits

Password-protected PDFs cannot be merged until the protection is removed in a program you trust. Very large files are limited by your device's memory, not by this site.

Need the opposite? Use Split PDF to take pages out of a document.
