When applying for a PAN card or filing correction documents through the UTI Infrastructure Technology and Services Limited (UTIITSL) online portal, accurate image formatting is critical. The UTIITSL Signature Resizer 400x200 is an automated online tool designed to optimize scanned signature files precisely to 400 × 200 pixels, convert density to 600 DPI, and compress the file size under 30 KB.
Why Use 400x200 Dimensions for UTI Signature Upload?
UTIITSL accepts signatures formatted with a 2:1 width-to-height aspect ratio. Standard mobile photographs often fail portal uploads due to invalid DPI metadata or excessive file size. Key advantages of this utility include:
- Automatic 600 DPI Header Injection: Modifies internal JFIF headers to embed mandatory 600 DPI metadata required by government validation algorithms.
- Precise 400x200 Canvas Processing: Eliminates image stretch and distortion by locking aspect ratios during cropping.
- Sub-30KB Auto Compression: Iterative browser-side compression shrinks memory footprint below 30 KB without degrading dark ink contrast.
- Client-Side Processing Security: Images are processed inside your browser memory—no signature data is saved on remote servers.
Step-by-Step Instructions to Format Your Signature
- Upload Signature: Click the selection box above and choose a photograph or scan of your signature.
- Adjust Selection Box: Position and resize the crop frame over your signature strokes.
- Convert Image: Click the "Resize Signature" button to adjust dimensions to 400×200 px and inject 600 DPI.
- Save File: Download the processed JPEG file and upload it directly to the UTIITSL PAN portal.

Frequently Asked Questions (FAQ)
What is the signature file size limit for UTIITSL applications?
The signature file must be in JPEG format and strictly smaller than 30 KB.
How do I resolve "Invalid DPI" errors on the UTIITSL website?
Using standard image editors often leaves the DPI at 72 DPI. Uploading your signature through this tool embeds the mandatory 600 DPI header metadata directly into the image structure.
What ink should be used for the digital signature?
It is recommended to sign on clean white paper using dark blue or black ink to maximize optical scan legibility.
