How many photos fit in 20 KB?
| Each page is… | Size per page | Pages that fit | Realistic? |
|---|---|---|---|
| Photo of a text document, grayscale | 15–60 KB | 0–1 | ⚠️ One page at most, at reduced quality |
| Photo of a certificate or ID in colour | 40–120 KB | under 1 | ❌ Unlikely — even one page needs heavy quality loss |
| Ordinary photo (people, places) | 80–250 KB | under 1 | ❌ Unlikely — even one page needs heavy quality loss |

Tips
- Crop each photo to the paper's edges before adding it — background wastes bytes.
- Choose “Small file” quality for text documents.
- Only include the pages the form asks for; every page shares the same 20 KB.

What if it can't reach the size?
