How to Scan Your CNIC & Documents to PDF on Your Phone

For job forms, admissions, and online portals in Pakistan — make a clean, accepted PDF scan in minutes, no app needed.

Scanning an identity card and documents into a clean PDF using a phone

Applying for a job, a university admission, or an online government service almost always means uploading your CNIC and a few documents. Most portals ask for a PDF, not a phone photo — and a blurry, tilted photo often gets rejected. The good news: you can make a clean PDF scan straight from your phone, free, with nothing to install.

Scan to PDF in 4 steps

Open the document scanner on your phone's browser, then:

  1. Allow camera access and place the document on a flat, dark surface.
  2. Capture the page — the scanner auto-detects the edges and straightens it.
  3. Add more pages if needed (for example, multiple certificates).
  4. Save as a single PDF and upload it to your form.

Prefer to use photos you already took? Add them to the Image to PDF tool and combine them into one PDF instead.

Tip: Good light is everything. Natural daylight near a window gives the cleanest, most readable scan.

Scanning both sides of a CNIC

Most forms want the front and back of your CNIC. Capture each side, then add both so your PDF has two pages (or place them on one page if the form asks for that). Check that the CNIC number and your name are sharp and fully readable before you upload.

Privacy note: Your CNIC is sensitive. Everything here is processed inside your browser and never uploaded to any server — your images stay on your device. Still, only submit it on official, trusted portals.
