Drop your photo, get a JPEG inside the TNPSC apply portal’s published windows — 300–400 px wide, 250–400 px tall, under 50 KB — for One Time Registration and every notification after it. Everything runs in your browser; nothing leaves your device.
Every Tamil Nadu Public Service Commission application — Group 1, Group 2/2A, Group 4, Combined Technical Services and the rest — runs through one profile on the commission’s apply portal (apply.tnpscexams.in), and the portal publishes its resize guideline right on the Guidelines-and-Instructions page, before you ever log in. The current official numbers, verbatim from that guideline: photograph 300–400 pixels wide, 250–400 pixels tall, JPG/JPEG, less than 50 KB; signature 200–300 × 150–250 pixels, JPG/JPEG, less than 20 KB; supporting documents 600–800 × 900–1200 pixels as JPG — or PDF — less than 200 KB. This page has PixFit preset to 320×400 at a 48 KB target — inside both pixel ranges, and 49,152 bytes stays under “50 KB” whichever way the server counts kilobytes. Drop your photo, adjust the crop, download, upload.
TNPSC’s own guideline walks you through the fix in MS Paint: resize to the pixel window, save, then — step 4, verbatim — “check the size, if it is more than 50 kb then reduce the pixels again to some extent”. That’s a manual guess-and-check loop, and every pass through it shrinks your photo’s pixels just to chase a byte count. Landing under 50 KB at the best quality the pixel window allows is a search problem: PixFit binary-searches the JPEG quality for you, keeps the pixels at 320×400, and lands the byte target in one pass. Same destination as the official procedure — without the loop, and without giving up resolution you’re allowed to keep.
Search “TNPSC photo resize” and the top tools confidently state the spec as 275×354 pixels, or 125×165, or “207×268 at 150 DPI” — three different tools, three different numbers, and none of them appears in the commission’s own guideline, which gives ranges: 300–400 wide, 250–400 tall. (275×354 is actually outside the official window — 275 is narrower than the stated 300-pixel minimum.) Several of the same tools also claim a 20 KB minimum for the photo and 10 KB for the signature. The commission’s guideline publishes no minimum at all — only the caps. We couldn’t verify a floor anywhere first-party, so this page hedges it honestly: the preset pads the output to at least 22 KB with spec-valid padding every image parser ignores. If the form has no floor, a 22 KB file is simply a valid file under 50 KB; if it enforces the floor the tools claim, you clear it. Either way you don’t fail.
Sign with a dark pen on white paper, photograph or scan it, and crop tight to the ink. For the signature pass, change the Exact size field to 250x150 (inside the official 200–300 × 150–250 window) and the target to 19 KB. The signature tool does the cleanup automatically — finds the ink, trims to it, whitens the paper — or draw one there directly. Applications uploaded without a photograph or signature, the notification warns, are “rejected after due process” — and once submitted, nothing can be corrected, so it’s worth getting both files right before you start.
Certificates and other supporting documents get their own window in the same guideline: 600–800 × 900–1200 pixels — roughly an A4 page in portrait — under 200 KB, as JPG or as a PDF under the same cap. For a photographed certificate, set Exact size to 700x1000 and the target to 195 KB; to upload it as a PDF instead, the image-to-PDF page wraps the fitted image into a one-page PDF that’s guaranteed under the cap.
TNPSC’s One Time Registration is exactly that — registered once, “valid for five years from the date of registration” (the commission’s own notification wording), across every notification you apply to. The commission publishes notifications year-round — as this page is written, the latest listed is 06/2026 (Combined Technical Services, July 2026). Fix the photo and signature properly once and every application for the next five years is a formality.
Registration and applications happen at apply.tnpscexams.in; the resize guideline is linked from its Guidelines-and-Instructions page, public, no login needed. A photo tied to your government job profile has no business passing through a resizer’s server — and most TNPSC photo tools are exactly that: server-side uploads. PixFit runs entirely in your browser: the photo never leaves your device, and the re-encode strips EXIF metadata (including GPS) as a side effect. An iPhone HEIC drops straight in; the output is a portal-ready JPG. Applying to central-government exams too? The full verified table covers UPSC, SSC, IBPS and sixty more — and Kerala PSC’s Thulasi if you’re applying across state lines.
Spec source: the TNPSC apply portal’s own “Photo, Signature & Support Document Resize” guideline PDF, linked from the live Guidelines-and-Instructions page at apply.tnpscexams.in, and the commission’s official notification PDFs (OTR validity and rejection wording), all read July 2026. These numbers have been stable for years but can change — if the upload screen disagrees, believe the portal.
