Frequently Asked Questions (TNPSC OTR Guidelines)
Official rules and guidelines for Tamil Nadu Public Service Commission registration
Q1.Why does the TNPSC portal reject signatures saying "File size less than 10 KB"?
When candidates crop a small signature to 6.0 cm × 2.0 cm, standard image compressors often reduce the file to 4–8 KB. The TNPSC OTR server algorithm strictly rejects any upload below 10 KB to ensure legibility. Kagazo solves this by applying 300 DPI high-chroma sampling and safe JFIF padding, guaranteeing your output always lands comfortably in the 13–18 KB sweet spot.
Q2.Is it mandatory to print the Candidate Name and Date of Photograph (DOP)?
Yes! According to the official TNPSC Instructions to Applicants, the photograph must have a clear white rectangular strip at the bottom containing the candidate's full name in capital block letters and the date on which the photograph was taken. Photos without this stamped strip are flagged and rejected during application scrutiny.
Q3.What is the date requirement for the Date of Photograph (DOP) on TNPSC?
The photograph must have been taken within three months prior to the date of notification. The date printed on the bottom strip must clearly reflect this recent capture date in DD/MM/YYYY format.
Q4.Can I download all 3 processed files together in one click?
Yes! Once you format your photo with name/date banner, signature, and left thumb impression, you can click "Download All 3 Files" to receive all three compliant assets sequentially named (`tnpsc_photo.jpg`, `tnpsc_signature.jpg`, `tnpsc_thumb.jpg`), ready for immediate OTR upload.
Q5.Can I use blue ink for my TNPSC specimen signature?
Yes. Unlike certain central boards that mandate black ink only, TNPSC officially accepts both blue and black ink signatures on clean, unruled white paper. However, signatures signed in CAPITAL letters or pencil will be rejected.
Q6.How long is a TNPSC One Time Registration (OTR) profile valid?
A TNPSC OTR profile is valid for 5 years from the date of initial registration. Candidates are required to renew their profile upon expiry and are strongly advised to update their photograph whenever their physical appearance changes or when applying for a major recruitment cycle like Group 4 or Group 2.
Q7.What format and file size are required for TNPSC certificate uploads like PSTM?
Educational marksheets (10th SSLC, 12th HSC), Community Certificates, and Persons Studied in Tamil Medium (PSTM) proofs must be uploaded in PDF format with file sizes strictly between 100 KB and 200 KB. Use Kagazo’s [TNPSC PDF Compressor (200KB)](/tools/compress-pdf-to-200kb).
Q8.What background color is mandatory for the TNPSC applicant photograph?
A plain white or very light off-white background is compulsory. Photos with colored walls, outdoor trees, busy patterns, or household furniture in the background are rejected during TNPSC document verification.
Q9.Can I wear spectacles or eye glasses in my TNPSC photo?
Regular prescription eyeglasses are permitted provided there is no glare or flash reflection covering your eyes. Sunglasses, tinted glasses, caps, hats, and religious headwear that obscures facial features from forehead to chin are strictly prohibited.
Q10.Does Kagazo upload or store my biometric photo, signature, or thumb print on any server?
Never. All cropping, banner stamping, contrast adjustment, and compression take place 100% in your local browser’s volatile RAM memory using client-side HTML5 Canvas. No personal identity files are ever transmitted across the network or stored on any server.
