.jpg Validation
JPEG validation that catches what extension checks miss
JPEG files are the most common image upload format — and the most commonly abused. Uplint validates structure, detects blank content, and scans for embedded threats.
Common JPEG Image Upload Issues
Solid-color JPEG images uploaded as placeholders
Truncated or corrupt JPEG files
Non-image files renamed to .jpg
JPEG files with embedded EXIF-based exploits
Oversized images uploaded to wrong context
What Uplint Validates
MIME type verification via magic bytes (FFD8FF header)
Image dimension and quality analysis
Single-color / blank image detection
JPEG structure validation (SOI, EOI markers)
Malware scanning
EXIF metadata analysis
