Jharkhand's OTR wants 4–30 KB in .jpg at a minimum of 200 DPI, in black ink on white. Its own guide disagrees with itself about the ink — below.

The Commission's wording on the upload screen: “A scanned signature in black ink on a white background must be uploaded in the designated space in the online application”, and “The image must have a minimum resolution of 200 DPI (dots per inch) and be in JPG format. The file should be between 4KB and 30KB”.
This is a genuine conflict inside a single official document, on a single page, and it is better to know about it than to be handed one answer with false confidence.
The OTR guide shows a screenshot of the Commission's upload screen. The instruction there reads “A scanned signature in black ink on a white background”. Directly below that screenshot, the guide's own prose summary says the signature “must be done in black or dark blue pen on white paper”. One of these permits dark blue and the other does not.
We treat black as the requirement, for one reason: the upload screen is the text a candidate actually reads at the moment of uploading, and the prose is a guide author's summary of it. So this page measures the hue of your strokes and tells you when they read as blue. But if you have already signed and scanned in dark blue, JPSC's own guide is on your side, and it would be dishonest of us to tell you the Commission has ruled it out. Signing again in black simply removes the question.
The same guide diverges from the upload screen in the other direction too: only the screen states the file sizes, the DPI minimum and the signature-consistency rule; only the prose asks that the image be neat and readable and cropped to the signature alone.
JPSC is unusually direct about this: the candidate must ensure the same signature is used across the uploaded signature, the undertaking, the attendance sheet and so on, and any variation in signature may result in cancellation of the candidate.
Because this is a One Time Registration, that has a longer reach than it does at a commission where you upload per application. The signature you put into your OTR profile today is the one you will be signing against in an exam hall for every JPSC recruitment you apply to afterwards. Upload the signature you actually write, not a carefully drawn one-off.
Search for JPSC photo requirements and you will be told 15–25 KB for the photograph and 10–15 KB for the signature, on coaching sites, news write-ups and form-filling guides alike. The Commission's own upload screen says 10–200 KB and 4–30 KB.
The photograph band is twenty times wider than the one being published, and its floor is lower, not higher. This is worth being precise about, because the usual scare framing does not apply: nobody is having an application rejected over this. A 15–25 KB photograph sits comfortably inside 10–200 KB and uploads fine. What actually happens is that candidates crush a perfectly good photograph down to a quarter of the size Jharkhand allows, and then it is that flattened image that gets printed on the admit card and looked at across a table.
The figures look stale rather than invented. A JPSC guidelines table published for the Civil Services Mains in June 2024 — a form that predates the OTR portal — carries wording very close to today's, and 15–25 KB with it. The likeliest story is that those numbers were right for that form and have simply been copied forward past the migration to One Time Registration. That is the ordinary way exam specifications go bad, and it is why every figure on this page is quoted against the document it came from.
JPSC asks for a minimal resolution of 200 DPI (dots per inch) on both uploads. DPI is a measure of pixels per unit of physical length, so on its own it says nothing about a digital file — you need a physical size before it means anything. The same 600-pixel-wide image is 200 DPI at three inches and 100 DPI at six.
And Jharkhand states no physical size anywhere. Not centimetres, not pixels, not an aspect ratio. “Passport photograph” is the only size word in the whole instruction and it is never defined. So the honest position is that 200 DPI cannot be converted into a pixel target from what JPSC has published, and any site that hands you an exact pixel size for JPSC has supplied the missing half itself without telling you.
Compare Uttar Pradesh, which also says 200 DPI: UPPSC states the centimetres as well, so its pixel size follows exactly and there is nothing to guess. Jharkhand gives you one half of the equation.
There is still something concrete to do about it, and almost nobody does it. A JPEG carries its own declared density in a JFIF header. Browsers and resizers that build a JPEG from a canvas write “1:1, no units” there — the file declares no resolution at all, and anything that reads it will assume 72 DPI or give up. This tool writes a real density into that header, so the file you upload actually states a resolution of at least 200 DPI rather than merely being big enough to have one.
Jharkhand runs a One Time Registration. The photograph and signature go into your OTR profile, and the Commission's own wording is that applicants need to upload their photo and signature only once, after which they populate automatically into every JPSC notification you apply under. They stay editable — the portal says personal details along with photo and signature are accessible and editable 24×7.
That cuts both ways. Getting it right once covers every future application; getting it wrong once follows you into all of them until you go back and fix it.
One thing worth knowing before you go looking for the portal: JPSC's OTR runs at jpscotr.com — a .com, not a .gov.in, with a helpdesk at helpdesk@jpscotr.com. It is genuinely the Commission's: jpsc.gov.in links to it by name from the left-hand rail of every page. We mention it because a state recruitment portal on a .com address is exactly the shape a phishing site takes, and the right way to reach it is by following the link from jpsc.gov.in rather than trusting a URL in a search result — including ours.
JPSC is the Jharkhand Public Service Commission at jpsc.gov.in — Combined Civil Services, Assistant Conservator of Forest, Forest Range Officer, Medical Officer and the rest. JSSC, the Jharkhand Staff Selection Commission at jssc.nic.in, is a different body running CGL, Lady Supervisor and its own examinations under its own upload rules. Both are “Jharkhand”, the abbreviations differ by one letter, and the figures on this page are JPSC's only. We have not checked JSSC's and do not publish them.
Nor is this JKPSC, the Jammu & Kashmir Public Service Commission.
Same application, different file. Each has its own limits — they are not interchangeable.
Between 4 KB and 30 KB, in JPG, at a minimum resolution of 200 DPI. A scanned signature in black ink on a white background. JPSC states no pixel dimensions and no centimetres for the signature either.
It does, on the same page, and that is worth knowing rather than guessing at. The Commission's upload screen says a scanned signature in black ink on a white background. The guide's own prose summary, two inches below that screenshot, says the signature must be done in black or dark blue pen on white paper. The upload screen is what you see while uploading, so we treat black as the requirement and flag anything else - but if you have already signed in dark blue, the guide's own text supports you. Black avoids the argument.
No. The upload screen says between 4 KB and 30 KB. The 10 to 15 KB figure circulates widely and appears to be carried over from a pre-OTR form. It sits inside the real band, so it will not fail, but it is not what the Commission asks for.
JPSC does not say. Unlike the photograph there is not even a conventional physical size to fall back on, so this tool does not impose one - it keeps your own scan's proportions, trims to the signature, and reports the size the file would print at if read at 200 DPI so you can sanity-check it.
Because JPSC says so explicitly: the candidate must ensure the same signature is used across the uploaded signature, the undertaking, the attendance sheet and so on, and any variation may result in cancellation of the candidate. Since the OTR signature is reused across every JPSC application, the one you upload here is the one you will have to reproduce in an exam hall later.
Yes. JPSC asks you to upload a clear, cropped image containing only the signature. This page finds the ink automatically and trims to it, and you can drag the box to exclude a printed ruling line or a page edge.
White. The upload screen says black ink on a white background; the guide's summary says white paper. Both agree on this one. If your scan reads grey, the paper clean-up option lifts it back to white.
No. JPSC is the Jharkhand Public Service Commission at jpsc.gov.in. JSSC is the Jharkhand Staff Selection Commission at jssc.nic.in, a different body with its own rules that we have not checked.
No. The trim, the ink measurement and the compression all run in your browser on your own device. Your signature image is never transmitted.
No. The signature goes into your One Time Registration profile once and is reused across every subsequent JPSC application. That is also why consistency matters more here than at a commission where you upload per application.
Yes. The portal states that personal details, along with the photo and signature, are accessible and editable at any time. If the one you uploaded is not the one you actually write, replace it.
Yes. It is linked by name from jpsc.gov.in, carries the Commission's crest and its helpdesk address. The .com is unusual for a government portal, so reach it through the link on jpsc.gov.in rather than from a search result.
It could. These figures are from the OTR user guide, which governs the profile upload. Check the advertisement for the recruitment you are applying under.
Specifications on this page are taken from the One Time Registration user guide published by the Jharkhand Public Service Commission — specifically from the Commission's own Instruction for photograph and Instruction for signature panel, which the guide reproduces from the Sign & Photo step of the portal:
The guide carries no version number and no date. It also contradicts itself on ink colour: the upload screen it reproduces says black ink, while its own prose summary allows black or dark blue. We treat the upload screen as operative and say so on the page rather than resolving it silently.
JPSC states no pixel or centimetre dimensions for either upload, so any pixel figure here is our arithmetic from a standard passport size and is labelled as such. The 15–25 KB and 10–15 KB figures circulating for JPSC are not the Commission's; its upload screen states 10–200 KB and 4–30 KB.
These are OTR profile requirements, reused across applications; an individual advertisement may state something different, so check the one you are applying under. This is JPSC (Jharkhand Public Service Commission), not JSSC (Jharkhand Staff Selection Commission, jssc.nic.in) and not JKPSC. We are not affiliated with any of them.
