Where does a 30 KB cap turn up?
| Form | Specification |
|---|---|
| Older state recruitment portals | Photo under 30 KB, JPEG only |
| Legacy university admission forms | Passport photo, 20–30 KB |
| Some state scholarship portals | Photo 30 KB max, signature 20 KB max |
When are you asked for this size?
- State government recruitment forms that still carry a 30 KB cap
- University admission portals built before file limits were relaxed
- Scholarship applications where photo and signature have separate caps

The pixel reduction does most of the work here, not the quality drop. Going from 12 megapixels to 46,000 pixels removes 99.6% of the data before JPEG quality is touched at all — which is why a head-and-shoulders crop survives 30 KB and a full-body shot does not.
Why 30 and not 50?
Because the limit was set when it was expensive to store. A portal built in the early 2010s sized its uploads for the bandwidth of the time, and nobody has revisited the number since — the form still works, so it never reached anyone’s list. That is also why 30 KB caps cluster in state portals rather than central ones: the central portals were rebuilt, and the state ones were not.
Frequently Asked Questions
Will a photo still look acceptable at 30 KB?
A head-and-shoulders photo on a plain background, yes. The face stays readable and the portal will accept it. A photo with a patterned wall or fabric behind you will show visible blocking, because JPEG spends its remaining data describing the pattern instead of your face. Shoot against a plain wall before compressing.
What pixel size should I use for a 30 KB photo?
Most Indian exam and recruitment forms ask for 200 × 230 pixels for the photograph. Check your own form — a file that meets the 30 KB cap at the wrong dimensions is still rejected, and portals usually state both.
Why does my photo go below 30 KB rather than exactly 30?
The tool targets just under the cap, not exactly on it. Portals reject anything over the limit and accept anything under, so landing at 29 KB is safer than trying to hit 30.000 KB and risking a rounding difference on their side.
Should I use JPG or PNG for a 30 KB photo?
JPG. PNG is lossless and roughly 3 to 5 times larger for the same photograph, so a PNG that fits 30 KB has had to lose most of its pixels. Every Indian government and exam portal accepts JPEG for photographs.
Is my photo uploaded anywhere?
No. The compression runs in your browser using the Canvas API. The file never leaves your device, which matters when the photo is going onto a government form along with your identity documents.
