Crops to e-Chayan's exact 150 × 200 px under 150 KB — not the 200 × 240 every other guide publishes — and measures whether the result is sharp enough to survive OPSC's blur rule.

| File size | Less than 150 KB — no minimum is stated |
| Format | JPG or JPEG only |
| Background | Light colour, passport style |
| Quality | Not blurred — blurry images are rejected |
| Mandatory | Yes, along with the signature and thumb impression |
OPSC's wording: “The allowable size of the photograph must be less than 150 kb”, and “Enter 150 pixels in Horizontal and 200 pixels in Vertical”.
This is not a small discrepancy. In August 2026 we checked the three tool sites ranking for OPSC photo and signature resizing against the Commission's own upload guide. None of them matches it:
| Published elsewhere | OPSC's own guide | |
|---|---|---|
| Photograph | 200 × 240 px, max 100 KB | 150 × 200 px, max 150 KB |
| Signature | 140 × 60 px, max 50 KB | 200 × 100 px, max 150 KB |
| Thumb impression | not mentioned | 150 × 200 px, max 150 KB, mandatory |
The 140 × 60 signature figure is the IBPS and SBI banking template. We have now found those numbers copied onto six different recruitment bodies. It has never once been the body's actual requirement.
A candidate following any of those pages is rejected twice over: once for dimensions that do not match, and again for a missing upload they were never told about. The Commission's guide is linked at the foot of this page — read it rather than taking our word for it.
On the upload panel, in red, the Commission writes that the image resolution should be good and not blurred, and that applications with blurry images will be rejected. That is a real rejection ground and almost nobody mentions it.
What it does not do is publish a number. There is no DPI figure, no sharpness score, no threshold. So this tool measures the sharpness of the finished 150 × 200 image — the exact file the portal receives — and shows you the figure. That measurement is ours, not OPSC's, and we say so rather than dressing it up as an official pass mark. It is useful in the way a light meter is useful: a soft original that stayed soft after resizing will read low, and you can see that before you upload rather than after you are rejected.
OPSC asks for a photograph, a signature and a thumb impression, and its guide is explicit that the Save button only becomes available once all three are in place. Our signature page handles the second at 200 × 100, and the thumb impression page the third at 150 × 200.
OPSC's website is opsc.gov.in. Its “Apply Online” button sends you to opscechayan.in — the e-Chayan Online Recruitment Management System — which is a plain .in address rather than a government one. That is legitimate: it is linked from the Commission's own site and its upload guide is the document quoted here. But if you have been taught to check for .gov.in before typing anything personal, the hesitation is reasonable, and it is worth knowing in advance rather than at the moment you are asked for an identity certificate number.
One more thing from the portal itself: if you registered on OPSC's old portal before 5 August 2022, that account does not carry over. You have to register again on e-Chayan to apply for anything published since.
The state was officially renamed from Orissa to Odisha in 2011 and the commission followed, so the body is now the Odisha Public Service Commission. Older guides, and a good deal of search traffic, still say Orissa PSC. Same commission, same specification.
Do not confuse it with OSSC, the Odisha Staff Selection Commission, or OSSSC, the Odisha Sub-Ordinate Staff Selection Commission. Those are separate bodies with their own portals and their own upload rules. Nothing on this page applies to them.
Same application, different file. Each has its own limits — they are not interchangeable.
150 pixels wide by 200 pixels tall, in JPG or JPEG, and less than 150 KB. Those figures are from OPSC's own upload guide on the e-Chayan portal, which tells candidates to enter 150 in Horizontal and 200 in Vertical, and shows the upload field marked 150 px across and 200 px down with a note that the maximum image size is 150 KB.
No. We checked the three tool sites ranking for OPSC in August 2026 and all of them publish 200 by 240 for the photograph and 140 by 60 for the signature. Neither figure appears anywhere in OPSC's guide. The real ones are 150 by 200 and 200 by 100. The 140 by 60 in particular is the IBPS banking template, which we have now found copied onto six different recruitment bodies.
No. OPSC states 150 KB as a maximum and gives no floor at all, so nothing here is padded. At 150 by 200 pixels your photograph will land far below the ceiling anyway - 150 KB is generous for an image that small.
That is the Commission's wording, in red, on the upload panel: the image resolution should be good and not blurred, and applications with blurry images will be rejected. It does not publish a numeric threshold, so nobody can tell you exactly where the line is. What this tool does is measure the sharpness of the finished 150 by 200 image - the file the portal actually receives - and show you the figure, so you can see whether a soft original stayed soft after resizing.
OPSC asks for a passport size photo with a light colour background. It does not name a specific colour or require pure white.
Three: photograph, signature, and a thumb impression. All three are mandatory - OPSC's guide says the Save button only becomes available after all three have been uploaded. Most guides to OPSC do not mention the thumb impression at all.
If you registered on the old OPSC portal before 5 August 2022, yes. The e-Chayan portal states that such candidates must register again on the new portal to apply for anything published since.
Same commission. Orissa was renamed Odisha in 2011 and the commission's name changed with it. It is not OSSC or OSSSC, which are the Odisha Staff Selection Commission and the Odisha Sub-Ordinate Staff Selection Commission - separate bodies with separate rules.
No. The crop, the sharpness measurement and the compression all run in your browser on your own device. Your photograph is never transmitted.
Requirements on this page are quoted from the “How to upload Photo and Signature” guide published by the Odisha Public Service Commission on its e-Chayan application portal opscechayan.in, linked as “Apply Online” from opsc.gov.in, together with the portal upload screens reproduced inside it. OPSC states exact pixel dimensions, JPG/JPEG format and a 150 KB ceiling on all three uploads; it states no minimum file size and no DPI.
That document carries no version number or date, so check the advertisement you are applying under. Figures of 200×240 for the photograph and 140×60 for the signature circulate widely and appear nowhere in the Commission’s guide — the correct figures are 150×200 and 200×100, and a third upload, the thumb impression, is mandatory. Formerly the Orissa Public Service Commission; not OSSC or OSSSC. We are not affiliated with the Commission.
