Frequently Asked Questions

Common questions about TNPSC OTR uploads and error resolution

Q.Why does the TNPSC portal reject signatures saying "File size less than 10 KB"?

When candidates crop a small signature to 3.5cm × 1.5cm, standard compressors reduce the file to 4–7 KB. The TNPSC OTR server algorithm strictly rejects any upload below 10 KB. Kagazo solves this by applying 300 DPI high-chroma sampling and safe JFIF padding to guarantee the output is strictly between 12 KB and 18 KB.

Q.Is it mandatory to print the Candidate Name and Date of Photograph (DOP)?

Yes! According to official TNPSC Instructions to Applicants, the photograph must have a clear white rectangular strip at the bottom containing the candidate full name in capital block letters and the date on which the photograph was taken.

Q.Can I download all 3 processed files together?

Yes. You can click "Download All 3 Files" to get your compliant photo, signature, and left thumb impression sequentially named, or download each file individually.

Q.Does Kagazo store or send my photo and signature to any server?

Never. All processing happens 100% in your local browser’s volatile RAM memory using client-side HTML5 canvas. No files or personal identity assets are ever uploaded to any server.
