When Do You Need to Convert Images to PDF?

Government form submissions requiring all documents in one PDF (Aadhar, PAN, certificates)
Bank job applications (IBPS, SBI) requiring merged document upload
College admission portals needing marksheets as a single PDF
Scholarship portals requiring income and caste certificates merged
Court filings and legal submissions needing scanned documents in PDF

Method 1 — Convert Images to PDF (JPG to PDF)

Open our JPG to PDF Converter
Upload your images (JPEG, PNG) — multiple images = multiple pages
Drag to reorder images in the correct document order
Click “Convert to PDF” — download the multi-page PDF

💡 Tip: Compress images to 100–200KB each before converting. A 10-page PDF with 100KB images = ~1MB PDF, which fits most portal limits.
