How to merge PDF files

  1. Add your PDFs. Drop two or more PDF files on the page, or choose them with the file picker.
  2. Put them in order. Drag the files (or use the arrow buttons) into the order you want. Optionally enter a page range for any file.
  3. Merge and download. Select Merge, then download the combined file.

Frequently asked questions

Are my files uploaded?

No. This tool runs entirely in your browser, so your files never leave your device. It even works offline once the page has loaded.

Can I merge only some pages of a file?

Yes. Enter page ranges such as 1-3, 5 for any file, and only those pages are included.

Are bookmarks and links kept?

The pages are copied with their content, links and annotations. Bookmarks and interactive form fields from the original files aren't carried over into the merged file.

Can I merge password-protected PDFs?

Files that only restrict editing can be merged; the result is saved without those restrictions. Files that need a password to open aren't supported yet.
