As per the official guidelines, the passport photo must include a white border strip at the bottom displaying the candidate's full name (in capital letters) and the date of photography.

The signature scan must be cropped cleanly with no margins, displaying dark blue or black ink on white paper.
Applicants are instructed to sign within a box of 6.0 cm x 2.0 cm on a plain sheet of paper. The signature must be scanned and formatted to 230 x 75 pixels (or 275 x 118 pixels on specific group portals) and compressed down to between 10 KB and 20 KB in JPEG.
Open Signature Resizer ToolWhy Specs May Differ by Exam
Different recruitment portals under the TNPSC commission sometimes show minor inconsistencies in documentation texts.
While older guidelines mentioned 130x170 pixels for photos, modern portals scale images dynamically to 276x354 pixels. Competitor sites show outdated specs, which can lead to upload errors or blurry outputs on candidate OTR dashboards. Our resizer uses dynamic canvas sizing matching the modern 276x354 px (photo) and 230x75 px (signature) boundaries to ensure seamless verification.
