Common Mistakes to Avoid
Photo background not white: The most common rejection reason. Use a plain white wall with no shadows, patterns, or colour.
File size at the exact limit: If the limit is 50KB, uploading exactly 50KB can sometimes fail. Always target 45-48KB for a safe buffer.
Wrong file format: Always use JPG for photos and signatures, PDF for certificates and marksheets.
