Every year, a meaningful number of government exam applications get stuck — or outright rejected — at the photo upload step, not because the applicant used the wrong photo, but because the file itself didn't match the portal's technical requirements: wrong pixel dimensions, wrong file size, or wrong format. This guide walks through the process end to end using our own photo resizer as the example, and covers what to do when something doesn't work the first time.

Before you start: find your exact requirement

Open your exam's official notification PDF and locate the photo specification — usually in a section titled "Photograph and Signature Specifications" or similar. Write down three numbers:

The required pixel dimensions (for example, 200×230px)
The minimum and maximum file size in KB (for example, 20KB–50KB)
The required format (almost always JPEG/JPG)

Do not rely on memory of "what this exam usually asks for" from a previous year or from a friend who applied before. Specifications are set per notification and do change between recruitment cycles — always confirm against the current PDF for the exam you're applying to.

Step-by-step: resizing your photo

Start with a recent, well-lit photo. Use a photo taken within the last few months (check your notification's exact age limit for the photo), against a plain white or light background, with no cap, sunglasses, or heavy shadow across your face.
Open the matching resizer tool. Go to our 20KB, 50KB, 100KB, or 200KB photo resizer depending on which range your notification specifies — or use the passport-size resizer if your form uses the classic 3.5×4.5cm standard.
Upload your photo. Click the upload field and select your source photo. You'll see a preview and the original file's size and dimensions.
Set the exact numbers from your notification. Adjust the min/max KB fields and the width/height fields to match what you wrote down — don't assume the page's default preset is exactly right for your specific exam.
Click "Resize & Compress." The tool tries multiple quality levels automatically until the output lands inside your target KB range at your target pixel dimensions.
Check the result stats. Confirm the displayed file size and dimensions exactly match what your notification requires before downloading.
Download and rename the file sensibly (for example, "photo-ssc-cgl.jpg") so you can find it easily when your application form asks you to browse and upload it.

Troubleshooting

The tool can't get my photo small enough without it looking blurry

This usually means the source photo itself has a problem — heavy noise, poor lighting, or an already-compressed source (like a screenshot of a photo rather than the original file). Go back to your original camera photo if possible, or retake it in better light, and try again. A sharp, well-lit original compresses much more gracefully than a soft or grainy one.

My result is the right file size but the portal still rejects it

Double-check the pixel dimensions, not just the KB size — many portals validate both independently, and being right on one but wrong on the other still fails. Also confirm the file extension is .jpg or .jpeg, since some portals reject .png or .webp even if the size is correct.

My photo looks correct but the background isn't accepted

A resizer can't change your background color — if your original photo has a colored, patterned, or cluttered background, you need a new photo taken against a plain white or light wall or sheet before resizing.

I changed the DPI in another tool and the KB size didn't change

That's expected — DPI controls print resolution, not file size on screen. If you're trying to hit a KB limit, use a resizer tool like ours instead of a DPI setting. See our DPI guide for more on this distinction.

A quick word on privacy

Since this is a photo tied to your identity and a government application, it's worth knowing that our resizer processes your image entirely inside your own browser using the Canvas API — it is never uploaded to our servers or anyone else's at any point in the process.
