Why was my photo or signature rejected?
An application portal almost never tells you what actually went wrong. It shows one generic error and sends you back to the upload screen. Here are the eleven causes we see most often, and how to fix each one.
What the portal is actually checking
Almost every recruitment and examination portal in India runs the same three checks, independently of one another, the moment you select a file:
- Format — is this a JPG? Many portals accept nothing else, whatever the file is named.
- Dimensions — is the image within the permitted width and height in pixels?
- File size — is the file inside the permitted kilobyte range?
A file has to pass all three. This is why a photograph that looks completely correct on your screen can still be refused: it may be failing a check that has nothing to do with how it looks. It is also why "I reduced the size and it still will not go" is so common — reducing the file size does not fix a dimension or format problem.
A fourth check exists on some portals: a minimum file size. A file can be rejected for being too small, which catches people who compress aggressively until the "too large" error goes away.
The eleven causes, in the order we see them
1. The file is a few kilobytes outside the range
Most forms specify a range, not a ceiling. A file below the minimum fails just as surely as one above the maximum. Hitting a narrow range by hand is genuinely difficult, because JPEG quality and file size are not linearly related — dropping quality from 80 to 70 might remove 40 KB, and from 70 to 60 only 8 KB.
2. The photo came off an iPhone and is secretly HEIC
This is the single most under-diagnosed cause. Recent iPhones save photos as HEIC rather than JPEG. When you share or rename one it may still show as .jpg, but the data inside is HEIC and the portal reads the data, not the name. The upload fails with a format error that makes no sense to you.
Fix: on the iPhone, open Settings → Camera → Formats and choose "Most Compatible", then retake the photo. Alternatively, open the image in any tool that re-encodes it as a true JPEG — including this one.
3. The image carries an EXIF rotation flag
Phone cameras often store the picture in one orientation and attach a separate instruction saying "display this rotated 90 degrees". Your phone gallery obeys that instruction; many portals do not. The result is a photograph that looks upright everywhere except on the application form, where it appears sideways — and is rejected at verification, long after submission.
Fix: re-save the image through a tool that applies the rotation and strips the flag.
4. The aspect ratio is wrong, so the photo is stretched
If you force a photograph into a width and height whose proportions differ from the original, faces come out either squashed or elongated. Some portals detect the mismatch and refuse the file; others accept it and the rejection arrives at document verification instead, which is far worse.
Fix: crop to the correct proportions first, then resize. Where cropping would cut off part of the picture, use a fit-and-pad approach so white space is added rather than content removed.
5. A scanned signature is full of grey paper
A signature photographed on paper is mostly a texture of slightly-grey pixels, and texture is expensive to compress. That is why a simple signature can produce a file many times larger than the limit, and why pushing quality down to force it under the limit turns the ink into a smear.
Fix: whiten the paper and darken the ink before compressing. A clean two-tone image compresses dramatically better, so you get a file that is both smaller and sharper. Photograph the paper in even, indirect light — direct light creates a bright patch and a shadow.
6. The signature is in capital letters
Several forms explicitly state that the signature must be in running handwriting and not in block capitals, and that a signature in capitals will be treated as invalid. This is a human check at verification, not an upload check, so the file goes through and the problem surfaces much later.
7. The background is not plain, or is too dark
Where a plain light background is specified, a photograph taken against a patterned wall, a door frame or a curtain can be rejected on inspection. Strong backlighting — a window behind you — produces a dark face against a bright background, which is also commonly refused.
Fix: stand about a metre in front of a plain, light-coloured wall, facing a window, with the light on your face rather than behind you.
8. The original is tiny and has been enlarged
Taking a small image — a forwarded picture, a screenshot, an old file — and scaling it up adds pixels but no detail. Enlargement cannot recover information that was never captured.
Fix: always start from the largest original you have, ideally straight from the camera.
9. The same file was uploaded into two different slots
When a form asks for a photograph, a signature, a thumb impression and a declaration, it is easy to select the wrong file for one of the four, particularly on a phone where thumbnails are small.
Fix: rename each output clearly before you start — photo.jpg, sign.jpg, thumb.jpg, declaration.jpg — and upload them one at a time.
10. The browser is re-sending a cached older file
If you fix a file, save it over the old one with the same name, and upload again without reloading, the browser can submit the version it already has in memory. You then see the identical error and conclude your fix did not work.
Fix: save each attempt under a new name, and reload the upload page before trying again.
11. The session expired while you were fixing the file
Application portals time out, often within fifteen minutes. If you leave the form open while editing images, the upload may fail for reasons entirely unrelated to the file.
Fix: prepare every image before you open the application form.
A method that avoids all eleven
- Collect the original, full-resolution photograph, and a signature written in black ink on plain white paper.
- Read the official notification PDF for your exam and your year, and write down the required dimensions and size range for each document.
- Prepare every file first, before opening the application form.
- Give each file a distinct, obvious name.
- Open the form, and upload the prepared files one at a time.
Step two matters more than people expect. Requirements are revised between cycles, and figures republished on coaching sites and news portals are frequently copied from an older notification. The official PDF for your own year is the only authority.
आम सवाल (Common questions)
Photo size kam karne par blur ho jata hai, kya karein?
Blur ka matlab hai ki aap pixel dimensions theek rakhte hue JPEG quality bahut neeche la rahe hain. Pehle image ko sahi dimensions par crop kijiye, uske baad compress kijiye. Agar phir bhi size zyada hai, to original photo hi low quality ka ho sakta hai.
Signature ka file size bahut zyada aa raha hai, jabki signature chhota hai
Kaagaz ka grey texture file size badha deta hai, signature ki ink nahi. Paper ko white aur ink ko dark karne wala clean-up option on kijiye — size apne aap kaafi kam ho jayega aur signature saaf bhi dikhega.
JPG likha hai phir bhi format error aa raha hai
Agar photo iPhone se hai to andar se wo HEIC ho sakti hai, chahe naam .jpg ho. Use kisi tool se dobara JPEG mein save kijiye.
