UPSC Photo & Signature Resizer

The exact UPSC photo and signature specs

The UPSC One Time Registration (OTR) and every exam application built on it check the same numbers. The portal accepts JPG or JPEG only, and it reads the pixel size and the file size before it will store the image:

Field	Pixels	File size	Format	Background
Photograph	350 × 350 px	20–300 KB	JPEG	Plain, light
Signature	350 × 150 px	20–100 KB	JPEG	White paper

The photograph is square, which trips people up: a normal phone photo is portrait, so it must be cropped to a true 1:1 square before it will read as 350×350. The signature is landscape, wider than it is tall. Both tools above are pre-set to the correct shape, so you only drop the file in and the crop is handled for you.

UPSC also asks that the photograph be recent, with your face clearly visible against a plain light background, and many candidates add the date the photo was taken across the bottom. Add that caption before you drop the file in, so it is baked into the 350×350 image the portal stores.

Why UPSC rejects a photo or signature

The upload fails for a small number of reasons, and all of them are fixable before you submit:

• Not JPEG. UPSC is strict here. A PNG, a HEIC file from an iPhone, or a PDF is refused outright. Both tools output JPG by default, so this stops being a problem.
• Wrong dimensions. A camera photo is thousands of pixels across. The form wants 350×350 for the photo and 350×150 for the signature. The tools resize to those exact numbers.
• Outside the KB range. The photo must sit between 20 and 300 KB and the signature between 20 and 100 KB. A raw photo is far larger; the tool brings it inside the range while keeping it sharp.
• Face too small or off-centre. UPSC wants the face to fill most of the frame against a plain background. Centre your face before uploading, since the tool crops from the middle of the image.

You never have to guess a number. Drop the file in and the tool prints the final pixels and KB so you can check them against the table before you upload.

Getting the UPSC signature right

The signature fails more often than the photo, usually because the image is too faint or badly cropped:

• Black ink on plain white paper. Black gives the contrast the portal needs. Avoid blue gel pens and lined paper.
• Sign at a natural size, then crop to the ink. The 350×150 landscape frame suits a signature that runs left to right. Sign, then photograph or scan just the signature so the frame lands on the writing, not on empty paper.
• Flat, even light. If you use a phone, hold it level above the page in daylight so no grey shadow falls across the paper. A shadow reads as a smudge and can get the signature rejected.

Drop that image into the signature tool and it crops to 350×150 and fits it inside the KB range. If your signature sits to one side of the sheet, crop roughly around it first so the centre crop lands on the ink.

Pixels and kilobytes, done in one pass

Most resizers change the pixels and then stop, leaving you to shrink the file with a second tool. Resizing to 350×350 does not by itself put the file inside 20 to 300 KB, and that gap is where people get stuck the night before a deadline. These tools do both at once: crop to the exact UPSC size, then tune the JPEG quality until the file lands inside the range, keeping the sharpest version that fits. One drop, one download, both boxes ticked.

Sitting a bank exam as well? The IBPS photo and signature resizer is pre-set to that portal's 200×230 and 140×60. For the PAN card that most applications ask for alongside, the PAN photo and signature resizer handles the NSDL 213×276 and 354×157. To hit any other portal's numbers, the resize-by-pixels tool takes any width and height and the reduce-size-in-KB tool hits any exact KB target.
