Quick response: select the documents, drag them into the correct order and create a single PDF. In Luna4 content is processed within the browser and does not need to be sent to a server.

Why local processing matters

A PDF can contain contracts, invoices, files, or personal information. A local tool reduces exposure because the browser reads and combines the pages on your device. The Luna4 account only controls the plan and number of operations; does not receive the document.

Steps to join several PDF

  1. Open the tool to join PDF.
  2. Select two or more documents.
  3. Checks the name and number of pages in each file.
  4. Drag the cards until they are placed in the final order.
  5. Press “Join PDF” and download the resulting document.

How to order correctly

Before processing, think about the reader: cover, index, contents and annexes. If they are monthly receipts, order them by date. If a page is rotated, fix it first with the rotate tool PDF and then rejoin the files.

Common problems

The document has a password

An PDF encryption can prevent the browser from copying your pages. Open the file with the password in an authorized application, and save an unprotected copy only if you have permission.

The result weighs a lot

Joining documents does not automatically reduce images or fonts. The final weight is close to the sum of the original files.
