What is PPI and why is it important?

PPI (Pixels Per Inch) measures the pixel density of an image or display. Higher PPI means sharper, more detailed images. It's crucial for determining print quality, screen clarity, and image resolution requirements.

Can I use this tool without uploading an image?

Yes! You can manually enter the image dimensions (width and height in pixels) and the screen diagonal size (in inches) to calculate PPI without uploading any files.

What image formats are supported?

The tool supports common image formats including JPG, JPEG, PNG, GIF, and WebP. The maximum file size is 10MB for optimal performance.

How is PPI calculated?

PPI is calculated using the formula: PPI = √(width² + height²) / diagonal size. The tool extracts image dimensions automatically from uploaded files or uses your manual inputs.

What do the quality classifications mean?

Low PPI (< 100): Suitable for basic web use. Medium PPI (100-200): Good for standard displays. High PPI (200-300): Excellent for high-resolution screens. Retina PPI (>300): Ultra-sharp quality for premium devices.
