PAN Card Signature Resize – DPI, Pixel aur KB Setting Kaise Kare
Updated on • Author: RK Resize Editorial
PAN application me signature image ko sahi pixels, DPI aur file size (KB) me tayyar karna zaroori hai. UTI me aksar 1000×200 px (≤60KB) ka strip chalta hai, jabki NSDL me अक्सर 4.5×2 cm @ 200 DPI (≈ 354×157 px) ka reference diya jata hai (KB low, e.g., ≤20KB). Rules portal ke notice ke hisaab se बदल सकते हैं — upload se pehle latest specs zaroor dekhen.

DPI vs Pixels – simple समझ
Pixels वह real size है जिसे portal verify करता है (e.g., 1000×200). DPI print density है — 200 DPI ka matlab 1 inch (2.54 cm) me 200 pixels. Pixels निकालने का basic formula:
pixels = (centimeters ÷ 2.54) × DPI
- NSDL ref: 4.5×2 cm @ 200 DPI ≈ (4.5÷2.54×200) × (2÷2.54×200) ≈ 354×157 px (approx).
- UTI: direct 1000×200 px दिया रहता है (DPI advisory).
NSDL vs UTI – Signature Specs (Typical)
| Parameter | NSDL (Typical) | UTI (Typical) | Notes |
|---|---|---|---|
| Pixels / Size | ~4.5×2 cm @ 200 DPI (≈ 354×157 px) | 1000 × 200 px (strip) | Portals kabhi-kabhi update karte hain; latest notice देखें |
| DPI | 200 DPI common | 300 DPI recommended | DPI informational; pixels/KB upload ke liye key |
| File Size (KB) | ≤ 20KB (common) | ≤ 60KB | Quality slider se control |
| Background | Plain white | Plain white | Grey/dirty background reject kara sakta hai |
| Format | JPG/JPEG | JPG/JPEG | sRGB |

Why borders नहीं आते?
RK Resize tools me frame cover-lock hota hai—zoom minimum isi tarah set hota hai ki black borders ना आएं.
Perfect Settings: KB & Quality
| Portal | Target KB | Suggested Quality | Expected Result |
|---|---|---|---|
| NSDL | ≤ 20KB | ~0.78–0.88 | Clean lines, readable strokes |
| UTI | ≤ 60KB | ~0.80–0.90 | Sharp sign, minimal artifacts |
Note: Noisy/grey background se KB बढ़ता है. Clean capture → lower KB at higher quality.
Capture/Scan Tips (Best Results)
- Pen: Blue/Black ball pen; gel/ink jo failti ho usse bachen.
- Paper: Plain white A4; sign beech me karein.
- Scan/Camera: Scanner 300 DPI; mobile me phone bilkul upar, even lighting, koi shadow/glare nahi.
- Crop: Sirf signature area rakhen; upar–neeche halka margin.
- Rejection aaye? Pixels, KB, background, orientation (landscape) dobara check karein, phir re-export karein.

FAQ
Q1: Grey background ko kaise sudharein?
Fresh white paper par sign karke dobara photo/scan lein. Grey background KB bada deta hai aur rejection ka risk badhata hai.
Q2: JPG ya PNG?
Portals commonly JPG/JPEG accept karte hain. Hamare tools JPG export dete hain (sRGB) — upload friendly.
Q3: Kya same signature image NSDL & UTI dono me chalegi?
Usually नहीं, kyunki pixels/KB alag hote hain. Dono portals ke liye unke specs ke hisaab se export karein.
