Resize Photo & Signature for SSC, UPSC, IBPS Forms

By MavexTech · Updated 16 October 2026 · 9 min read

To upload a photo and signature on SSC, UPSC or IBPS forms, crop each image to the right shape, resize it to the pixel size in the notice, then compress it as a JPG into the allowed KB range, typically 20 to 50 KB for the photo and 10 to 20 KB for the signature (UPSC allows up to 300 KB). Always confirm the exact limits in your exam’s notification.

Why exam portals reject photos and signatures

Online application portals check every upload automatically. If a file breaks any rule, the portal either refuses it on the spot or, worse, accepts it and the application is later rejected during scrutiny. The usual reasons are:

• File size outside the KB range. Too large (a 3 MB phone photo) or too small (an over-compressed 8 KB file when the minimum is 20 KB).
• Wrong pixel dimensions. Some portals want an exact size such as 200 × 230 pixels; others accept a range.
• Wrong format. Most want JPG/JPEG. PNG, HEIC (iPhone) and WEBP files are often refused.
• Poor photo quality. Blurred, dark or shadowed face, coloured or cluttered background, caps or dark glasses, or a selfie taken at an angle.
• Bad signature scan. Faint pencil, signature in capital letters, too much empty paper around it, or a signature signed by someone else.

The fix is almost always the same three steps: crop to the right shape, resize to the right pixels, then compress to the right KB range.

Typical photo and signature specs (SSC, UPSC, IBPS)

Each recruitment body publishes its own rules in the notification for every exam, and they do change. The table below shows the specifications commonly seen in recent notifications. Use it to understand the targets, then confirm against the notice you are applying for.

Specs as seen in recent notifications. Always check the official notice on ssc.gov.in, upsc.gov.in or ibps.in before uploading; if it differs from this table, the notice wins.

Other common forms (state PSCs, railway RRB, university admissions, passport and visa) use similar ranges. A safe general target is a JPG photo of 20 to 50 KB and a JPG signature of 10 to 20 KB, unless the notice says otherwise.

KB, pixels and centimetres: what each one means

Notices mix three different measurements, and confusing them is the most common reason for failed uploads.

Pixels: the shape and detail

Pixels (px) are the dots that make up a digital image. “200 × 230 px” means 200 dots wide and 230 dots tall. If the notice gives an exact pixel size, your file must match it; if it gives a range, stay inside it.

Centimetres: a print size

Some notices describe the photo as, say, 3.5 cm × 4.5 cm. A digital file has no fixed physical size; the link between centimetres and pixels is the resolution in DPI (dots per inch, with 1 inch = 2.54 cm):

When a notice gives only centimetres, around 200 DPI usually gives a sensible pixel size that still compresses into a 20 to 50 KB range.

KB: the file size

KB (kilobytes) is how much storage the file takes. Most upload checks treat 1 KB as 1,024 bytes, so 50 KB = 51,200 bytes, 20 KB = 20,480 bytes and 10 KB = 10,240 bytes. A file of 50,500 bytes is 49.32 KB and passes a 50 KB limit; a file of 51,300 bytes is 50.1 KB and fails. Windows File Explorer also counts in 1,024-byte KB; if you are close to the limit, check the exact byte count in the file’s Properties.

The same pixel size can produce very different KB sizes depending on JPEG quality. Uncompressed, every pixel takes 3 bytes (red, green, blue):

That is why a correctly sized 200 × 230 photo still needs JPEG compression to land inside 20 to 50 KB, and why a too-small file is usually a sign of over-compression or a very plain image, which can look blurry to an examiner.

Step by step: prepare your photo

1. Take a fresh photo. Plain white or light background, even light from the front (daylight near a window works), face straight to the camera, both ears and the full face visible, eyes open, no cap or dark glasses. Use the phone’s rear camera at arm’s length or ask someone to take it; front-camera selfies distort the face.
2. Check the date rule. Many notices want a photo taken within the last few months, and some ask for the photo to match the one you bring to the exam. Keep a print of the same photo.
3. Crop to the right shape. Crop from the top of the head to just below the shoulders, with the face filling most of the frame. Match the notice’s ratio: for 200 × 230 px, the crop should be slightly taller than it is wide.
4. Resize to the pixel size. Set exact pixels (for example 200 × 230) or stay inside the allowed range.
5. Compress to the KB range. Aim for the middle of the range, such as 30 to 45 KB for a 20 to 50 KB limit, so the file is clearly inside the limits and still sharp.
6. Save as JPG and name it simply, for example photo.jpg. Some portals reject names with spaces or symbols.
7. Open the final file and look at it at full size. If the face looks smudged, raise the quality slightly and recompress.

If your phone saves photos as HEIC (most iPhones do by default), convert the file to JPG first with the HEIC to JPG converter.

Step by step: prepare your signature

1. Sign on plain white paper with a black or dark blue ball-point or gel pen. Do not use pencil. Sign the way you will sign in the exam hall; signatures in block capitals are usually not accepted.
2. Photograph or scan it in good light without shadows. Hold the phone directly above the paper so the signature is not slanted.
3. Crop tightly around the signature, leaving only a small margin. A signature lost in a large white area looks tiny once resized.
4. Resize to the required pixels, for example 140 × 60 px, keeping the wide, short shape.
5. Compress to the KB range, usually 10 to 20 KB. Signatures are simple images and compress easily, so check that the file is not below the minimum.
6. Check readability. Every stroke should be visible at full size.

IBPS forms also ask for a left thumb impression (commonly 240 × 240 px, 20 to 50 KB) and a handwritten declaration (commonly 800 × 400 px, 50 to 100 KB) in your own handwriting, in English, using the exact text given in the notice. Prepare them the same way: black or blue ink on white paper, good light, tight crop.

Troubleshooting upload errors

If the notice gives a very specific size, such as “between 20 KB and 50 KB”, the precise tool is a target-size compressor where you type the KB you want. For a different target, such as 100 KB for a declaration, use a tool that lets you set any size.

A quick checklist before you click upload

• JPG format, file opens correctly on your phone or computer.
• Pixels and KB both inside the notice’s limits.
• Photo is recent, sharp, front-facing, on a plain light background.
• Signature is your own, in dark ink, tightly cropped and readable.
• Photo and signature are uploaded in the correct boxes (a common mix-up).
• Keep copies of all final files and a printout of the photo for exam day.
