A rejected photograph is one of the more frustrating ways to lose an application, because it usually happens at the last minute and the error message rarely says what is actually wrong. "Invalid image" covers a dozen different causes.
Here they are in roughly the order they occur, with what to do about each.
1. The file is under the minimum size
This one catches almost everyone, because it is counterproductive. You compress a photo to get it under 50 KB, overshoot, land at 8 KB, and the portal refuses it.
Most Indian exam portals specify a band — 20 KB to 50 KB, say — and reject files on either side of it. A file that is too small is refused exactly like one that is too large.
The fix is not to re-take the photo at higher quality and hope. It is to compress to a target that sits inside the band. Our custom resizer lets you set both the floor and the ceiling, and lifts an undersized file over the floor without touching the picture. There is a longer explanation in why portals reject files that are too small.
2. The pixel dimensions are not exact
Banking exams are the strict ones. IBPS and SBI ask for a photograph of exactly 200 x 230 pixels. Not "about" 200 x 230. A file at 201 x 230 is refused.
Other bodies give a range instead — UPSC accepts anything from 350 x 350 to 1000 x 1000 — and a few give physical dimensions in centimetres, which you then have to convert at a stated DPI.
Read your notification carefully for which of the three it is. If it states a single pair of numbers, treat them as exact.
3. The format is wrong
Nearly every Indian portal wants JPEG. Some accept PNG for signatures. Very few accept anything else.
Renaming photo.png to photo.jpg does not convert it, and the portal will detect that. The file has to be genuinely re-encoded. Opening it in any resizer and exporting as JPEG does this properly.
4. There is no name and date on the photo
UPSC, NTA (so NEET, JEE Main and CUET) and several state commissions require your name and the date the photograph was taken printed on the photo itself, usually as a strip below your face.
This is not optional and it is not something the portal checks automatically — a human sees it later, which is why people find out at the document verification stage rather than at upload. Our guide on adding your name and date covers the format.
5. The photo is too old
RRB notifications commonly require a photograph taken within the last one month. SSC asks for three months. TNPSC's one-time registration expires after five years and asks you to refresh.
There is no automated check for this either. It surfaces during verification, when someone compares the photo to you.
6. The background is busy or dark
Almost every notification asks for a plain, light background — white or off-white. A photograph taken against a patterned wall, a curtain, or in a room where your head casts a shadow onto the wall behind you will be questioned.
Stand about a metre away from a plain wall rather than against it. That distance is what stops the shadow falling where the camera can see it.
7. The face is too small or too large in the frame
The usual requirement is that the face occupies 70 to 80 per cent of the frame height, from the top of the head to the chin, centred, looking straight at the camera.
A full-length photo cropped down to passport size fails this, because the resolution is not there and the face ends up small and soft. Take the photo at the right distance rather than cropping in afterwards.
8. It is a selfie, or has a filter
Notifications increasingly say this outright. Selfies are recognisable — the arm's-length angle, the distortion from a wide front-facing lens, the uneven lighting. Beauty filters and "portrait mode" background blur are also grounds for rejection.
Have someone else take it, on the rear camera, with no effects.
9. Caps, glasses and uniforms
No cap or headgear, except where worn for religious reasons, and then the full face must still be visible. No dark glasses. Clear spectacles are usually fine as long as there is no glare on the lenses — if there is, take them off.
Some notifications also prohibit uniforms.
Before you upload
Run through this quickly:
- Colour photograph, plain light background
- Face 70 to 80 per cent of the frame, front-facing, neutral expression
- No cap, no dark glasses, no filter, no shadow behind the head
- Name and date printed on it, if your board requires them
- Taken recently enough for the notification
- Exact pixel dimensions, JPEG, and a file size inside the stated band
Our resizer checks the last three automatically and flags blur, a dark or busy background, a black-and-white photo and face position before you download. It cannot check whether the photo is recent or whether you are wearing a cap — those are still yours to get right.
