TOOL GUIDE

Guide to merging multiple PDFs into one file

Applications, manuscript files, CV attachments, certificates, and scanned pages are often required as one PDF. Sending many separate files is messy and increases the chance of missing something.

Toolardo Merge PDF combines multiple PDFs into one output file in the order you choose.

When is this useful?

  • Combining an application with its attachments
  • Collecting manuscript or submission documents
  • Joining a CV and certificates
  • Merging pages created by separate scans

How to use it

  1. Add the PDF files.
  2. Check the file and page order.
  3. Rearrange them if necessary.
  4. Run the merge and download the new PDF.
Good to know

Check page orientation and size before merging. A4, Letter, portrait, and landscape pages can coexist, but the final document may look inconsistent if the source files use very different layouts.

How it works

  1. 1Choose the required file or enter the source data.
  2. 2Set the available options and run the tool.
  3. 3Download the generated result.
