How to Combine Certificates into One PDF

Reviewed and updated August 21, 2026

Application portals often want one PDF instead of many images.

Steps

1. Convert each certificate with JPG to PDF or start from existing PDFs
2. Open Merge PDF
3. Order documents as required by the form
4. Compress if there is a size cap

Choose an order the reviewer can follow

Follow the application instructions when they specify an order. Otherwise, group related documents logically—for example identity documents, academic certificates, experience records, and supporting evidence. Keep front and back scans together.

Combine images and existing PDFs

1. Convert certificate photos or scans with JPG to PDF
2. Open each result and confirm orientation
3. Add all PDFs to Merge PDF
4. Drag files into the required order
5. Download and inspect every page
6. Compress the complete packet if necessary

Protect important details

Do not compress so strongly that names, registration numbers, seals, signatures, or QR codes become unreadable. Keep a high-quality master and create a separate upload copy. Redact unrelated personal information only when the receiving organization does not require it.
