Official Photo & Signature Guidelines for Indian Exams (2026)
Every recruitment commission sets strict pixel boundaries and file size quotas. If your file exceeds 50 KB by even 1 single byte, the portal automatically throws a rejection error:
| Exam / Board | Document | File Quota | Dimensions | Background |
|---|---|---|---|---|
| SSC (CGL, CHSL, MTS) | Photograph | 20 KB to 50 KB | 3.5 × 4.5 cm | White / Light |
| SSC (All Exams) | Signature | 10 KB to 20 KB | 4.0 × 2.0 cm | Black Ink |
| UPSC (Civil Services) | Photograph | 20 KB to 300 KB | 350×350 px min | Clear White |
| IBPS / SBI Banking | Photograph | 20 KB to 50 KB | 200 × 230 px | White BG |
Top 3 Reasons Portals Reject Photos
iPhones default to HEIC/PNG. Portals strictly mandate pure .JPG / .JPEG.
If your file is 18KB, portals reject it because minimum is 20KB. We target 35KB safely.
Wearing caps, tinted glasses, or colorful backgrounds causes disqualification.
Frequently Asked Questions (Exam Photo & Signature)
What are the exact photo dimensions and file size for SSC CGL, CHSL, and MTS? ▼
The passport photo must be in JPEG/JPG format between 20 KB and 50 KB with dimensions of roughly 3.5 cm width × 4.5 cm height (approx 100 × 120 to 350 × 450 pixels). The signature must be between 10 KB and 20 KB with dimensions of 4.0 cm width × 2.0 cm height.
Why does the SSC portal show error 'File size must be between 20KB and 50KB'? ▼
SSC enforces both an upper limit (50KB) and a lower limit (20KB). If your file is compressed too much (e.g., 18KB), the portal rejects it. Our tool automatically targets ~35KB safely in the middle of the allowable zone.
Do I need to write my name and date on the photo for SSC 2025–2026 exams? ▼
Under latest SSC notices, unless specifically mandated in the notification, standard passport photos without name or date stamps are accepted. Live webcam capture is used in newer portals, but for scanned uploads, plain white background without caps or spectacles is strictly enforced.
How do I resize an image to 20KB on an Android phone or iPhone? ▼
Open this page in Chrome or Safari on your phone, select the SSC Photo or Signature preset, choose your image from gallery, and tap download. It compresses to the exact allowable KB size locally in milliseconds with zero app downloads.
Are my uploaded photos or signatures saved on any server? ▼
No. BuyWiseHub processes images entirely inside your browser's local memory using HTML5 Canvas. Your sensitive identity documents never leave your phone or computer.
How does the tool achieve exact file sizes like 20KB without blurring? ▼
Our engine uses an iterative binary search compression algorithm. It automatically calculates the optimal JPEG quality factor and pixel density, preserving facial clarity and signature stroke sharpness while staying strictly under the threshold.
