Thulasi's wording: “Your signature in the uploaded image must be clear and legible.”
The photograph and the signature share a width and not a height. The photograph is 150 × 200; the signature is 150 × 100. It is an easy thing to get wrong, and plenty of guides do — several published pages quote 150 × 200 for both, which would give you a signature twice as tall as Thulasi accepts. The figure on Kerala's own Step 4 screen is 150W × 100H, and the diagram beside it is labelled the same way.
Fifteen thousand pixels is not much to hold a signature. A wide, looping signature scanned at full page width has to come down a long way to fit, and thin strokes are the first thing to go. This tool finds the ink in your scan, trims to it, and measures the contrast between the strokes and the paper before it shrinks anything — so if your pen is too faint to survive the reduction you hear about it here rather than from the portal.
Thulasi asks for a signature that is clear and legible and says nothing about colour. Blue or black on white paper is sensible and scans well, but it is not a published rule, so we do not enforce one. For comparison: MPSC requires black, GATE permits black or dark blue, and Karnataka, Telangana and Andhra Pradesh all state nothing.
30 KB is a ceiling and Kerala gives no floor. At 150 × 100 pixels your signature will come out well under the limit regardless, so there is nothing to pad and nothing here pads it.
Two commissions answer to KPSC. This page is the Kerala Public Service Commission, at keralapsc.gov.in, whose registration portal is Thulasi at thulasi.psc.kerala.gov.in and whose published contact address is kpsc.psc@kerala.gov.in. The Karnataka Public Service Commission is at kpsc.kar.nic.in and applies through kpsconline.karnataka.gov.in.
Their specifications have almost nothing in common. Karnataka publishes no dimensions at all and sets a minimum file size on every upload — 50 KB to 200 KB for the photograph. Kerala publishes exact pixel dimensions, caps the file at 30 KB and states no minimum. A file built for one is wrong for the other in every respect. Our Karnataka page is here.
Same application, different file. Each has its own limits — they are not interchangeable.
Exactly 150 pixels wide by 100 pixels tall, in JPG, and no more than 30 KB. Thulasi's Step 4 screen states all three, and the diagram on that screen labels the frame 150 px across and 100 px down.
No, and this is the mistake worth avoiding. The photograph is 150 by 200; the signature is 150 by 100. The width matches, the height does not. Several guides repeat 150 by 200 for both, which would give you a signature twice as tall as Thulasi wants.
Kerala does not specify one. Thulasi's requirement for the signature is that it be clear and legible, and that is all it says. Blue or black on white paper is the conventional advice and it scans well, but the commission has not made it a rule, so this tool measures whether your strokes read clearly rather than policing their colour.
No. Kerala caps the signature at 30 KB and states no floor. At 150 by 100 pixels a signature will land far below that anyway, so nothing needs padding - and nothing here pads it.
No. That requirement applies to the photograph only. The signature just has to be clear and legible at 150 by 100 pixels.
Kerala. Both commissions use the abbreviation KPSC. Kerala PSC is at keralapsc.gov.in and registers through the Thulasi portal; Karnataka PSC is at kpsc.kar.nic.in and applies through kpsconline.karnataka.gov.in. Karnataka wants a signature between 50 KB and 70 KB with no dimensions given at all - the opposite arrangement to this page in every respect.
No. The trim, the legibility measurement and the compression all run in your browser on your own device. Your signature image is never transmitted.
Requirements on this page are quoted from the new-registration procedure published by the Kerala Public Service Commission (linked from its OTR Instructions page), and from the Thulasi upload screens reproduced inside it. Kerala states exact pixel dimensions, a JPG format and a 30 KB ceiling; it states no minimum file size, no DPI and no ink colour.
That document carries no version number or date and its screenshots are footed 2012, so check the notification you are applying under — Kerala’s own sources disagree on how recent the photograph must be and on when its ten-year validity starts, and both disagreements are set out above. This is Kerala PSC (keralapsc.gov.in), not Karnataka PSC (kpsc.kar.nic.in), which shares the abbreviation KPSC and has an entirely different specification. We are not affiliated with either.
