Phone scans, photos of notes, and JPGs from your camera often need to be a single PDF for uploads (college portals, job applications, e-KYC). Converting them one-by-one as images looks unprofessional and fails most portal validations.
Here’s how to turn any JPG/PNG into a clean, shareable PDF in seconds.
Why Convert JPG/PNG to PDF?
- One file for multiple images: 10 photos → 1 PDF (easier to email, upload)
- Portals require PDF: Government, college, and job portals accept PDF only, not JPG
- Universal viewing: PDF looks identical on every device; JPGs can appear stretched
- Print-ready: PDF preserves page size/margins for printing

Step 3 — Arrange & settings
- Reorder/rotate: Drag to reorder pages; rotate any image 90° if sideways

Settings Explained
Fit vs A4:
Fit— each page exactly the image size; no white border — best for photosA4— standard A4 pages with centered images — best for documents/certs that will be printed
Orientation:
Auto— keeps original image orientation (recommended)Portrait— forces vertical; good for ID proofsLandscape— forces horizontal; good for wide scans
Margin:
0— edge-to-edge (photos)10–15 mm— clean white border for documents
Pro Tips
Scan with your phone, convert, then compress. Phone photos at 12 MP create huge PDFs. After converting, run through Compress PDF to shrink from 12 MB → 2 MB for portal limits.
Keep order clear. Rename images 01-AadhaarFront.jpg, 02-AadhaarBack.jpg before upload — reorder then is instant.
All JPGs offline? ModifyPDF processes locally where possible — your photos don’t need to be emailed to yourself first.
JPG vs PNG for PDF
- JPG: Smaller size, great for photos/scans. Slight compression.
- PNG: Larger but lossless — best for screenshots, diagrams with text.
ModifyPDF accepts both.
Common Use Cases
Student: 8 photos of handwritten notes → one PDF for classroom upload
Professional: Site photos + invoice JPGs → one PDF report for client
KYC: Front/back photos of ID → one PDF for portal (many portals explicitly ask for one PDF, not two JPGs)
Troubleshooting
“PDF is sideways” Rotate the image in the tool before converting (no need to edit the JPG separately).
“File too large for upload (portal says max 2 MB)”
Use A4 + margin 10 mm (slightly smaller), then Compress PDF → Target 1900 KB.
“Images look stretched”
Use Fit + Auto orientation to preserve original aspect ratio.
