Why Government Exam Portals Require 200 DPI Scanning

When filling online applications for UPSC OTR, SSC CGL/CHSL, or State Public Service Commissions, the official notifications specify: "Set the scanner resolution to a minimum of 200 DPI (dots per inch) in True Color."

72 DPI (Standard Mobile)
Too low for official print verification; rejected due to pixelation on admit cards.
200 DPI (Official Standard)
Optimal sharpness with compact file size (<50KB-200KB). Guaranteed portal acceptance.
300 DPI+ (Print High-Res)
Ideal for physical photo studio prints, but file sizes exceed exam portal limits.

Frequently Asked Questions (200 DPI Converter)

Why do UPSC and SSC exam notifications mandate 200 DPI for scanned documents?

Official recruitment portals like UPSC (Union Public Service Commission) and SSC specify scanning at 200 DPI because it delivers the optimal balance between razor-sharp ink legibility and a manageable file size (under 200KB or 50KB). Scanning at 72 DPI produces blurry text, while 600 DPI creates massive files that fail upload limits.

How does SizeSnap change image DPI to 200 without degrading quality?

SizeSnap rewrites the standard JFIF APP0 binary header of your JPEG file, embedding the exact 200 DPI horizontal and vertical density values. The pixel matrix and colors are untouched unless you optionally choose 2x or 4x high-resolution upscaling.

Can I verify the 200 DPI metadata after downloading?

Yes. On Windows, right-click your downloaded image, select "Properties" → "Details" tab, and verify horizontal and vertical resolution show 200 dpi. On macOS, open the file in Preview and press Cmd+I ("Image Inspector"). You can also use SizeSnap's "Image Metadata Viewer" tool.

Is my scanned certificate or ID card uploaded to any server?

No. All image processing and JFIF header modification occur 100% inside your local web browser via JavaScript. Your private marksheets, Aadhaar card, and identity documents never touch an external server.

What is the difference between 200 DPI and 300 DPI?

DPI (Dots Per Inch) determines print density. 200 DPI is the standard for online screen verification and exam document scans. 300 DPI is standard for physical high-gloss photo printing and passport/visa biometrics. You can select either 200 DPI or 300 DPI using the toggle buttons above.
