Summary

Sign on plain white paper with a dark pen. Photograph it with your phone in good light (or scan it). Use SarkariKagaz.pro to crop and resize it to your exam's exact dimensions and KB limit.

Why Your Signature Upload Matters

Almost every Indian government exam requires a separate signature upload alongside your photograph. The signature is used for identity verification at the examination centre, during document verification rounds, and throughout the entire selection process. An illegible or incorrectly formatted signature can cause issues even after you've cleared the written exam.

This guide explains exactly how to prepare, scan, and upload a perfect signature for any government exam portal.

Step 1: Sign on the Right Paper

The quality of your signature upload starts with the physical signature itself.

Paper: Use plain white A4 paper or a clean blank page. No lines, no ruled paper, no colour paper.
Pen: Use a dark blue or black ball-point or gel pen. Avoid light blue ink, pencil, or felt-tip pens that bleed.
Signature size: Sign in the middle of the page, leaving good margins on all sides. Make your signature about 5–7 cm wide — not too tiny, not covering the whole page.
Consistency: Use the same signature you use on your official documents and ID cards. It will be compared at document verification stages.

Method 1: Scan Using a Flatbed Scanner

A flatbed scanner gives the best results — clean, sharp, no perspective distortion.

Place the signed paper face-down on the scanner glass
Set scan resolution to 200–300 DPI
Set colour mode to Colour (not grayscale, even for black signatures — portals prefer colour JPEG)
Save as JPEG format
Open SarkariKagaz.pro, select your exam, go to "Add Signature" mode
Upload the scanned image and use the crop tool to isolate just your signature
Download — the tool auto-resizes and compresses to your exam's exact KB limit

Method 2: Photograph with a Smartphone (Most Common)

Most candidates use their phone camera — this works perfectly if done correctly.

Place the signed paper on a flat, clean surface (not the floor — use a table or desk)
Ensure good, even lighting. Natural daylight from a window works best. Avoid direct sunlight (creates glare) or dim indoor lighting (creates shadow)
Hold your phone directly above the paper — not at an angle. The paper should fill most of the camera frame
Tap the screen to focus on the paper before taking the shot
Take the photo — check that the signature is sharp and the background is clearly white
Upload to SarkariKagaz.pro, crop to just the signature area, and download

⚠️

Common phone photography mistakes

Photographing at an angle — creates trapezoid distortion
Shadow from your hand or body falling on the paper
Using flash — creates glare and washes out the ink
Paper not flat — creates uneven lighting

Method 3: Use a Scanning App (CamScanner, Adobe Scan)

Scanning apps use your phone camera but add automatic perspective correction and enhancement:

Download CamScanner, Adobe Scan, or Microsoft Office Lens (all free)
Open the app and photograph your signature
The app automatically crops and corrects perspective
Save as JPEG (not PDF)
Upload to SarkariKagaz.pro to resize to your exam's exact specifications

Frequently Asked Questions

No. Government exam portals require a handwritten signature on plain white paper, scanned or photographed. A digital signature (typed or created in software) will not be accepted as it cannot be verified against your physical signature at the examination centre.

Both dark blue and black ink are acceptable for most exams. Dark blue is slightly preferred as it appears clearly against white paper and photographs well. Avoid light blue, red, or green ink — they may not scan clearly.

Shadows usually come from photographing at an angle or with a direct light source. Fix it by placing the paper in diffused natural light (near a window but not in direct sunlight), holding your phone directly above the paper (perpendicular), and making sure your body is not casting a shadow over it.

Yes! Upload the larger photo of your signature paper, use the Crop tool in SarkariKagaz.pro to select just the signature area, and then download. The tool will resize and compress it to the exact specifications of your selected exam.
