Frequently Asked Questions

What image formats are supported?

Our calculator supports all major image formats including JPG, PNG, GIF, WebP, BMP, and TIFF files up to 10MB in size.

How accurate are the calculations?

All calculations are performed using precise algorithms that read the actual image metadata and file properties for 100% accuracy.

What is the aspect ratio calculation?

Aspect ratio is the proportional relationship between width and height, expressed as a ratio (e.g., 16:9, 4:3) or decimal value.

How do you calculate print size?

Print size is calculated based on image dimensions and DPI (dots per inch). We use 300 DPI as the standard for high-quality printing.

Is my image data secure?

Yes, all analysis happens locally in your browser. Your images are never uploaded to our servers, ensuring complete privacy.

What are megapixels?

Megapixels represent the total number of pixels in an image divided by one million. Higher megapixels generally mean more detail and larger file sizes.
