How to merge PDF files neatly

A practical guide to combining multiple PDFs into one file without messing up the page order.

When should you merge PDFs?

Merging PDFs is useful when separate documents need to be sent as one file, such as administrative attachments, modules, invoices, or registration documents.

File order matters

Before processing, make sure the file names and upload order are correct. If the document has a cover page, place it first so the final PDF is easy to read.

Check the result before sending

After the merged file is ready, open it and check the first page, last page, and a few pages in the middle. This helps catch rotated pages or missing files.

Quick tips

• Use clear file names before uploading.
• Avoid merging password-protected files before unlocking them.
• Download the result soon because temporary files are automatically deleted.
