Step 1: Check Current Signature Dimensions

• Right-click your signature image file

Step 2: Use Image Editing Software

• Open your signature in any photo editor (Paint, GIMP, Photoshop, or online tools)
• Navigate to “Resize” or “Image Size” option
• Set dimensions to exactly 50mm x 20mm (approximately 189 x 76 pixels)
• Maintain aspect ratio to prevent distortion

Step 3: Optimize File Size

• Save the resized image as PNG or JPG format
• Adjust quality settings to keep file under 20KB
• If file exceeds 20KB, reduce quality slightly until it meets requirements

• Ensure signature remains clear and readable

Why Signature Size Matters for RTO/Parivahan

The RTO signature upload error is one of the most common issues faced by DL applicants. Here’s why proper sizing is crucial:

Technical Requirements The Parivahan portal has strict validation rules for uploaded documents. Signatures that don’t meet the exact 50mm x 20mm specification are automatically rejected by the system.

Processing Efficiency Standardized dimensions ensure smooth processing of applications across different RTO offices in India. Oversized files can slow down the system and cause delays.

Document Integrity Proper sizing maintains the signature’s clarity and authenticity, which is essential for official verification processes.

Common Upload Errors

• “File size too large” – occurs when DL signature size in KB exceeds 20KB limit
• “Invalid dimensions” – happens when signature isn’t exactly 50mm x 20mm
• “Unsupported format” – occurs with formats other than PNG or JPG

Before Resizing
