DPI Upscaler & Checker
Check if images meet 300 DPI printing standards, and intelligently restore blurry low-resolution images using AI super-resolution technology.
Features
- DPI Detection: Read and verify image DPI information
- Intelligent Analysis: Calculate actual print size and pixel density
- Super-Resolution Restoration: Use Real-ESRGAN algorithm to enhance image clarity
- Batch Processing: Support single image and batch folder processing
- Format Support: JPG, PNG, TIFF, BMP, WebP
Use Cases
- Academic paper figure DPI checking
- Print image quality pre-inspection
- Low-resolution material restoration
- Document scan enhancement
