❌ Why Your Photo Upload Gets Rejected

The recruitment portal applies strict automated filters to incoming files. If your image breaches any parameter, the session halts. Common reasons for the "Photo Upload Error" include:

• Photos of signatures taken under poor yellow lighting.
• Shadows of the phone falling onto the paper while capturing.
• Cropping too loosely, including wooden tables or thumbs in the frame resulting in high file size.

🛠️ Step-by-Step Guide: How to Fix & Resize

You don't need expensive photo editing software to fix this. Follow these three steps to generate a compliant image:

1. Upload your Original Image: Take a clear photo from your phone. Don't worry if it's 5MB.
2. Set the Target Size: Navigate to our dedicated resizing tool specifically built for the Universal Signature Forms portal. Select the target KB limit.
3. Compress and Download: The tool will instantly rewrite the image headers and compress the pixels to the exact allowed file size without warping your face.

💡 Expert Tip: Reducing KB Without Losing Quality

Take a photo of your signature during bright daylight next to a window. Avoid casting shadows with your phone. A completely white background dramatically reduces the file size naturally.

Best File Format: Always save and upload your images in JPEG (.jpg) format. Even if a portal claims to support PNG or PDF, JPEG is universally processed without server errors on older government infrastructure.
