For Staff Selection Commission (SSC) recruitment portals:

• Photograph: 20 KB to 50 KB in JPEG format, dimensions of 200 x 230 pixels (3.5 cm width x 4.5 cm height). Must have 80% face coverage with light/white background and no spectacles or head coverings (except religious).
• Signature: 10 KB to 20 KB in JPEG format, dimensions of 140 x 60 pixels (4.0 cm width x 2.0 cm height) in running handwriting with black/dark blue ink.

The primary reasons for application form rejections are:

• Wearing spectacles or sunglasses causing lens glare or reflection.
• File size outside the allowed window (e.g. 52 KB when the limit is 50 KB).
• Blurry or shadowed signature photographed from mobile without pure white paper background.
• Missing candidate Name and Date of Photo (DOP) when explicitly mandated by notifications (e.g. UPPSC, Bihar Police).

Sarkari Resizer uses an automated binary-search algorithm on HTML5 Canvas export compression. Instead of blindly degrading your image, it calculates the highest possible JPEG visual quality factor that ensures the resulting file size sits strictly within the portal’s minimum (e.g. 20 KB) and maximum (e.g. 50 KB) boundary.

For Union Public Service Commission (UPSC) One Time Registration (OTR) and exam applications:

• Photo: 20 KB to 300 KB, min 350 x 350 px to max 1000 x 1000 px, clear white background. Face should occupy roughly three-fourths of the photograph.
• Signature: 20 KB to 300 KB, min 350 x 350 px to max 1000 x 1000 px in black ink on white background.

Yes, 100% safe. All image manipulation, cropping, name stamping, and compression execute exclusively on your local device CPU/GPU through standard browser Canvas APIs. No file is ever transmitted over the network or saved to any backend server.
