When to use 40KB vs 30KB vs 50KB?
30KB
Best when the portal is stricter and only smaller image uploads are allowed.
40KB
Useful for forms and applications that allow slightly more file size with better clarity.
50KB
Better when the platform allows a bit more space and you want improved image detail.
If 30KB feels too small and 50KB is not required, 40KB is often a smart middle option.
