Merge PDF Files

Combine multiple PDFs into one document locally. Select files in the order you want their pages to appear.

Merge multiple PDF documents into one single file. Order depends on selection.

Combine documents in the right order

  1. Choose at least two PDF documents.
  2. Check their selection order and remove any unwanted files.
  3. Merge the pages and download the combined PDF.

Output and file-size behavior

Pages are copied into a new document. Merging does not compress embedded images, so the result may remain close to the combined source sizes. Encrypted PDFs must be unlocked before this tool can read them.
