UPPSC Photo and Signature Size: KB, cm and Scanning

From UPPSC's Guidelines for Scanning Photograph with Signature, the instruction sheet linked from the OTR section of uppsc.up.nic.in (read on 14 October 2026). Check the advertisement for your post as well, since individual notices can add requirements.

• Photograph: less than 50 KB, 5 cm wide x 6 cm high, scanned at 200 DPI in true colour.
• Signature: less than 30 KB, 6 cm wide x 3 cm high, scanned at 200 DPI in true colour.
• The signature must be your full signature, signed by you only. Initials are not enough and signatures in capital letters are not permitted.
• The signature is printed on your hall ticket. If the signature on your answer script does not match it at the exam, you are disqualified.

At 200 DPI, 5 x 6 cm is about 394 x 472 pixels and 6 x 3 cm is about 472 x 236 pixels. If you photograph the sheet with a phone instead of scanning it, resize each crop to those pixel sizes and you get the same result as a 200 DPI scan.

1. 1

   Prepare the sheet

   Paste a recent passport photo on plain white paper and sign your full signature in a clear space next to it with a dark pen, not in capital letters.

2. 2

   Scan or photograph it

   Scan the sheet at 200 DPI in colour, or photograph it flat in daylight from directly above. If the phone saves HEIC or PNG, convert it with Convert Image Format.

3. 3

   Crop the two images

   Open Crop Image twice on the same scan: once around the photo, keeping a 5 to 6 shape, and once around the signature, keeping a 2 to 1 shape.

4. 4

   Resize to the 200 DPI sizes

   In Resize Image set the photo to 394 x 472 pixels and the signature to 472 x 236 pixels.

5. 5

   Bring each under its limit

   Use Compress to 50 KB for the photo and Compress Image set to 30 KB for the signature. Each keeps the best quality that fits.

• Uploading the whole scanned sheet as one image instead of two crops.
• Signing with initials only, or in capital letters.
• A signature that does not match the one you sign at the exam.
• A grey, shadowed background from a phone photo taken at an angle.
• Leaving the files at full camera size, which is far above 50 KB and 30 KB.
