You're filling out a form and suddenly it asks for "200 DPI". You have no idea what that means, so you Google it, and now you're even more confused. DPI (Dots Per Inch) is the most misunderstood requirement in the history of online exams. Let's simplify it.
- Web / Screen: Usually 72 or 96 DPI. (Standard)
- Printing / Passport: 300 DPI. (High Quality)
- Kerala PSC: Specifically 200 DPI. (Don't ask why, just do it).

Here is the secret: DPI is just a text tag hidden inside your image file. On a screen, a 72 DPI photo and a 300 DPI photo look exactly the same if the pixel dimensions (e.g., 200x200 px) are the same. However, old government software reads this tag. If it sees "72" instead of "200", it rejects you. It's silly, but it's the rule.
