Which forms need a file under 30 KB
These uploads on the exams we cover have a maximum that this page fits. Each row links to the exam page, which also sets the exact pixel size.
| Exam | Upload | Allowed size |

| CTET | Signature | 3 to 30 KB |
Getting a clear image under 30 KB
- Crop tightly. At this size most of the bytes should go on the ink or the face, not on empty paper or wall.
- Keep the pixel size modest. A signature at about 280 × 120 pixels, or a small photo at about 200 × 230, fits easily and still looks sharp on the portal.
- Use good light. A shadowy phone photo has grainy patches that take up space and look smudged once compressed.
- If the form also sets a minimum size, such as 10 KB, the tool keeps the file above it as well.
