Official TNPSC signature instruction
The TNPSC instructions to candidates say, in short: draw a box of 6.0 × 2.0 cm (230 × 75 pixels) on white paper and sign inside it with a blue or black ink pen. Scan the paper at 200 DPI, crop the image to show only the box with the signature, keep it between 10 KB and 20 KB, save it as Signature.jpg and upload it.
தமிழில்: வெள்ளைத் தாளில் 6 செ.மீ. அகலம், 2 செ.மீ. உயரம் கொண்ட கட்டம் வரைந்து, அதற்குள் நீலம் அல்லது கருப்பு மைப் பேனாவால் கையொப்பமிடவும். அதை 200 DPI-இல் ஸ்கேன் செய்து, கட்டத்தை மட்டும் crop செய்து, 10 KB – 20 KB அளவில் "Signature.jpg" எனச் சேமித்துப் பதிவேற்றவும்.
How to compress a signature for TNPSC
- Sign on paper: Draw a 6 cm × 2 cm box on white paper and sign inside it with a blue or black pen.
- Take a clear photo: Photograph or scan the paper in good light with no shadow on the signature.
- Upload and crop: Choose the image and fit the crop box tightly around the signature box.
- Download Signature.jpg: Press Create signature and download the 230 × 75 px JPG between 10 KB and 20 KB.
Keep Make paper background white ticked. It turns grey or yellow paper into clean white and makes the ink darker, which is what a 200 DPI scan looks like.
TNPSC signature compressor to 20 KB and 10 KB
The upload fails if Signature.jpg is above 20 KB or below 10 KB. A phone photo of a signature is usually 1–4 MB, so it must be cropped and compressed. A clean signature on white paper is the opposite problem: after resizing to 230 × 75 px it can fall below 10 KB. This tool handles both, so the file always lands between 10 KB and 20 KB.
TNPSC signature size for Group 4, Group 2, Group 1 and VAO
The signature is uploaded once in your One Time Registration (OTR) and used for every TNPSC exam. So the TNPSC Group 4 signature size, Group 2 signature size and VAO signature size are all the same: 6.0 × 2.0 cm, 230 × 75 px, 10–20 KB JPG.

Tips for a clear signature
Use a gel or ink pen
A thick blue or black line stays sharp at 230 × 75 px. Avoid pencil and sketch pens.
Good light, no shadow
Photograph near a window. Hold the phone straight above the paper so the box is not slanted.
Crop only the box
Fit the crop box to the drawn 6 × 2 cm box. Do not include the rest of the page.
Rotate if sideways
Use the rotate buttons if the photo was taken in portrait mode.

Frequently asked questions
What is the TNPSC signature size?
The signature must be 6.0 cm wide and 2.0 cm high, which is 230 × 75 pixels at 200 DPI. The file must be a JPG between 10 KB and 20 KB, saved as Signature.jpg.
How do I compress my signature to 20 KB for TNPSC?
Upload a photo or scan of your signature, crop the signature box and press Create signature. The tool resizes it to 230 × 75 px and keeps the JPG between 10 KB and 20 KB automatically.
My signature file is below 10 KB. What should I do?
A plain signature on white paper is a very small image, so it often comes out below 10 KB. This tool saves it at the highest quality and, if it is still too small, adds safe padding inside the JPG so the file reaches the 10 KB minimum without changing how it looks.
Can I sign with a blue pen?
Yes. TNPSC allows blue or black ink. Black ink usually scans with better contrast. Sign inside a 6 cm × 2 cm box drawn on white paper.
Can I upload my signature as a PDF to TNPSC?
No. TNPSC asks for the signature as a JPG image named Signature.jpg. If your signature is inside a PDF, take a screenshot or photo of it and upload that image here to get a proper JPG.
Should the signature be in capital letters?
No. Sign the way you normally sign. Do not write your name in capital letters instead of signing. Use the same signature in the exam hall.
What is the TNPSC Group 4 signature size?
Group 4, VAO, Group 2, Group 2A and Group 1 all use the One Time Registration signature: 6.0 × 2.0 cm, 230 × 75 pixels at 200 DPI, JPG between 10 KB and 20 KB.
Why does the TNPSC portal say my signature is invalid?
The usual reasons are a file above 20 KB or below 10 KB, a PNG or PDF instead of JPG, or the whole page uploaded instead of the cropped box. Create Signature.jpg here and upload it again.
How can I scan my signature at 200 DPI on mobile?
You do not need a scanner. Take a clear phone photo of the signed box in good light. This tool resizes it to 230 × 75 pixels at 200 DPI, which is what a 200 DPI scan would give.
Is my signature stored?
The uploaded image is deleted right after processing. The finished Signature.jpg is kept for at most 2 hours for download and then deleted automatically.
