Combine resume, cover letter, and certificates into one PDF for job applications. Free online PDF merger, no signup, unlimited files.

Most job portals accept only one PDF upload. When you have a CV, cover letter, certificates, and a portfolio, you need to combine them into a single professional document — in the right order. ## How to Merge Job Application PDFs 1. Go to [pdfhub24.com/merge-pdf](/merge-pdf) 2. Upload all your documents at once 3. Drag to arrange them in the correct order (see below) 4. Click **Merge PDF** 5. Download and review the combined file 6. Compress if the portal has a file size limit ## The Right Order for Job Application Documents Recruiters read applications in a specific sequence. Structure your merged PDF to match: 1. **Cover letter** — your introduction, read first 2. **CV / Resume** — your professional history 3. **Certificates and qualifications** — degree, professional certifications 4. **References or reference letters** — if requested 5. **Portfolio or work samples** — if relevant to the role Some roles require specific documents in a specific order — always check the job listing or application instructions first. ## File Size for Application Portals Most ATS (applicant tracking systems) cap uploads at 5–10MB. If your merged file is larger — common when you have a design portfolio — compress it with [pdfhub24.com/compress-pdf](/compress-pdf) after merging. Medium compression preserves all text quality and reduces most portfolios from 20MB to 3–5MB. ## Preparing Each Document Before Merging **Scanned certificates:** Scan at 200 DPI greyscale rather than colour. One A4 page should come in under 200KB. Run [OCR](/ocr-pdf) if you want the text to be searchable. **Multiple certificates:** If you have 5–10 certificates, consider whether the recruiter needs all of them. Include the most relevant ones for the specific role. **Portfolio pages:** If your portfolio is large, extract only the best 5–10 samples using [pdfhub24.com/split-pdf](/split-pdf) before merging. ## After Merging — Final Checks Open the merged PDF and check: - Page order is correct - All pages are readable (no blank or cut-off pages) - File size is within the portal's limit - Your name and contact details appear early in the document
