Quick answer

Confirm that the portal wants one PDF, arrange your separate PDFs in the required order, merge them with the KitPadi PDF Toolkit and inspect the completed file page by page. Use a clear filename and check the total size before submission.

Merge or convert: which do you need?

Use PDF Merge when every source file is already a PDF. Use Image to PDF when your sources are JPG or PNG photographs. If you have both, convert the images to PDF first, then merge the resulting PDF with the other documents.

Choose a logical document order

Follow the portal or employer’s instructions first. When no order is stated, a readable sequence might be cover page or application letter, identity document, main qualification, supporting certificates and additional evidence. Do not add a cover page unless it is useful and permitted.

Merge the documents step by step

  1. Make a folder containing only the final documents.
  2. Rename them in order: 01-ID, 02-Degree, 03-Certificate and so on.
  3. Open PDF Toolkit and select Merge.
  4. Add the files and confirm their displayed order.
  5. Create and download the merged PDF.
  6. Check page count, orientation, clarity and file size.
  7. Save with a professional filename such as Ada-Okafor-Application-Documents.pdf.

Before you submit

  • Confirm that no page is blank, upside down or duplicated.
  • Check names and identification numbers for accidental exposure to the wrong recipient.
  • Open the first and last page to confirm the merge completed.
  • Compare the size with the portal limit.
  • Keep the original documents and the final submission copy.

Common mistakes to avoid

  • Merging documents when the portal asks for separate uploads.
  • Putting the strongest or required qualification at the end without checking instructions.
  • Uploading password-protected PDFs that the receiving system cannot open.
  • Using vague filenames such as scan001-final-new.pdf.
  • Trusting the merge without reviewing all pages.

Frequently asked questions

Does merging reduce quality?

A normal merge keeps the source pages rather than re-photographing them. The result should be inspected because damaged or protected files can still fail.

Can I change the order?

Yes. Arrange the PDFs before processing. Clear numbered filenames make mistakes less likely.

What if the merged file is too large?

Remove unnecessary pages and optimize oversized scans. See the related guide to reducing a PDF below 1MB or 2MB.
