1. Understanding File Size (KB vs MB)
When applying for government jobs in India (like SSC, UPSC, IBPS), you will often see limits like "Photo must be between 20KB to 50KB".
- KB (Kilobyte): Small size, perfect for signatures and passport photos.
- MB (Megabyte): 1024 KB. Usually allowed for high-quality documents and marksheet scans.
Our Image Resizer uses advanced compression algorithms to hit these targets without making your photo look blurry.
2. Official Passport Photo Dimensions
Different forms require different physical dimensions. Here are the most common ones:
| Application | Dimension (cm) | Pixels (approx) |
|---|---|---|
| Indian Passport | 3.5 x 4.5 cm | 413 x 531 px |
| SSC / UPSC | 3.5 x 4.5 cm | 413 x 531 px |
| PAN Card | 2.5 x 3.5 cm | 213 x 213 px |
Use our Passport Maker to automatically crop your photo to these exact sizes.
