Resize Photo and Signature for SSC, IBPS, UPSC and Other Exam Forms

Online application forms for Indian exams have strict rules for the photograph and signature: a size in KB, sometimes an exact size in pixels, sometimes a background colour, sometimes your name and the date printed under the photo. Get any of it wrong and the form will not submit, or worse, the application is rejected after the deadline. This guide explains what each requirement means and how to meet it reliably.

Pixels, KB and DPI are different things

Notifications often mix three units, and confusing them is the root of most problems.

• Pixels (px) are the dimensions of the image, for example 200 × 230 px. This is what "dimensions" means.
• KB is the file size on disk. Two photos with identical pixel dimensions can be 15 KB or 80 KB depending on JPEG quality and how much detail they contain.
• DPI (dots per inch) is a number stored inside the file that says how large the image should print. It does not change the pixels or the file size. When a notice says "3.5 cm × 4.5 cm", the portal usually checks pixels and KB, not physical size. Some portals do check the stored DPI.

So a correct photo usually needs: the right pixel dimensions, a file size between a minimum and maximum KB, and JPG format.

Typical requirements

The table below shows the sizes File Studio's presets use, based on recent notifications. These change between years and between exams, so always check the current notification and use the custom size option if anything differs.

Bank exams (IBPS, SBI) also ask for a left thumb impression and a handwritten declaration as separate uploads; the IBPS preset includes 240 × 240 px (20–50 KB) for the thumb and 800 × 400 px (50–100 KB) for the declaration. NTA exams have at times asked for a postcard-size photo as well.

Step 1: Take a good photo

A resized bad photo is still a bad photo. For the source image:

• Stand in front of a plain white or light wall, facing a window. Avoid overhead light that throws shadows under the eyes.
• Ask someone else to take it, from about 1.5 m away, at eye level, using the rear camera.
• Face the camera straight, eyes open, ears visible, no cap or dark glasses. Spectacles are usually allowed if there is no glare, but check the notice.
• Many exams want a recent photo, sometimes taken within a stated period before the application. Some ask that the photo be dated.

Step 2: Resize to the exact specification

1. Open Exam Photo & Signature and pick your exam preset, or enter custom pixel and KB values.
2. Add your photo. Adjust framing so your face sits in the upper middle with shoulders visible; most notices want the face to fill a good part of the frame.
3. Download. The tool outputs a JPG at exactly the required pixel size and adjusts quality to land between the minimum and maximum KB.

Before uploading, the tool can also check an existing file against the spec: it reports the actual pixels, the KB size, the real format (it catches PNGs renamed to .jpg), and the shape, so you can see exactly which rule is failing.

If an exam needs your name and date printed under the photo (UPSC and TNPSC do, and several state commissions), use the preset's name-and-date option or Name & Date on Photo. It adds a white strip with your name in capitals and the date of the photograph, in the proportion those exams expect.

Step 3: Prepare the signature

Signature uploads fail more often than photos, usually because of a grey background or a signature too faint to read at small sizes.

1. Sign on plain white paper with a black ink pen, a little larger than usual. Many notices specify black ink; a felt or gel pen gives a firmer line.
2. Photograph it in good light, phone held parallel to the paper.
3. Open Signature on White. Choose your exam's size, or "Any form: your px and KB".
4. Use Crop to the signature to trim empty paper, then adjust strength until the background is pure white without breaking thin strokes. Pure black & white gives the crispest look and the smallest file.

Sign the way you will sign at the exam centre. Your signature on the admit card may be compared with the one you sign on the day. Do not use capital letters if the notice forbids it, and never sign in all capitals unless that is genuinely your signature.

Common rejection reasons

• File size below minimum. Yes, files can be too small. A 140 × 60 px signature with clean white background may compress to 5 KB, under a 10 KB minimum. The exam tool raises quality to reach the minimum; if it cannot, slightly larger dimensions (if allowed) help.
• Wrong format. PNG, HEIC or WebP saved with a .jpg name. Convert properly; renaming does not change the format.
• Photo too dark, blurred, or with a shadow behind the head. Retake it near a window.
• Face too small. A full-body or half-body shot shrunk to passport size. Crop closer.
• Signature in capital letters or with name typed. Must be your real handwritten signature.
• Old photo. Some exams cross-check at verification and the photo must resemble you.
• Selfie with a mirror image. Front cameras flip text; any name strip will read backwards. Use the rear camera.

If a portal asks for a size in KB that you just need to hit for some other image, Compress Image can target any KB value.

A checklist before you click Submit

1. Open the downloaded photo and signature on your computer and check they are the right files, not old ones with similar names.
2. Confirm the size in KB in the file properties, and the pixel dimensions.
3. Check the preview on the portal after uploading. Some portals show a thumbnail; your face and signature should be clearly visible.
4. Save copies of the exact files you uploaded, and print a few copies of the photo. Admit cards and document verification may require the same photograph, and having a different one at the exam centre causes trouble.
5. Download or print the submitted form and confirmation page.

Privacy

These tools process your photo and signature in your browser. Your photo and signature are sensitive; avoid leaving copies on shared computers, and be careful with "photo studio" apps that ask for broad permissions.
