The Ultimate Guide to Resizing Passport Photos & Signatures to 20KB/50KB
### Document Specifications for Government Portals
Applying for national competitive exams (like **SSC, UPSC, Kerala PSC, or Banking exams**) is exciting, but uploading photos is often a frustrating experience. Government systems mandate strict regulations:
- **Passport Photo**: Usually between **20KB to 50KB**, with dimensions typically around 3.5cm x 4.5cm.
- **Signature Image**: Typically between **10KB to 20KB**, with standard aspect ratios.
If your upload is even 1KB over the limit, the system rejects it, occasionally resetting your entire application form.
