How to Prepare Documents for an Online Job Application as PDF

By Zainab Fuzail · Updated October 2026

Job portals often ask for a single PDF: your CV, a cover letter and sometimes certificates. A messy file can cost you attention before anyone reads it. This guide shows how to prepare clean PDFs, join them in the right order and keep the size within the portal’s limit.

Step 1: Read the Requirements

Step 2: Make Your CV a PDF

If your CV is a Word file, the best way is usually “Save as PDF” in Word itself, because the text stays selectable. Some employers use systems that read the text of a CV, and a PDF made of page images cannot be read that way. PaperDesk Word to PDF creates pages as images, so use it only when Word is not available, and read our guide on converting Word to PDF without surprises.

Step 3: Turn Certificates Into PDFs

Photograph or scan each certificate flat, in good light. Then use Image to PDF. It accepts JPG and PNG, and each picture goes on its own A4 page. Our guide on combining scanned documents shows the steps.

Step 4: Join Everything in the Right Order

  1. Open Merge PDF.
  2. Add the cover letter first, then the CV, then the certificates.
  3. Check the order in the list. Files are joined from top to bottom.
  4. Click “Merge PDFs” and download paperdesk-merged.pdf.

Rename the file clearly, for example “Ayesha-Khan-CV.pdf”, instead of leaving the default name.

Step 5: Keep the Size Within the Limit

Scans make a PDF large quickly. If the file is above the limit, use Compress PDF. In my test, a practice PDF of 6,789.4 KB became 541 KB with the Recommended level. Read our guide on meeting an upload size limit before you start.
