About This Tool

The Image DPI Checker helps you instantly check the DPI (dots per inch) resolution of any image file. Whether you're preparing images for print, optimizing for web use, or simply need to know your image specifications, this tool provides accurate information in seconds.

What is DPI?

DPI (Dots Per Inch) measures image resolution for printing. It determines how many ink dots are placed per inch when printing an image. Higher DPI values create sharper, more detailed prints but result in larger file sizes.

Common DPI Standards

  • 72 DPI - Standard for web and screen display
  • 150 DPI - Minimum for acceptable printing
  • 300 DPI - Professional print quality (photos, magazines)
  • 600+ DPI - High-end printing (fine art, large format)

How to Use

  2. View instant results showing DPI, dimensions, and file size
  3. Get recommendations based on your image's current DPI

Frequently Asked Questions

Why does my image show 72 or 96 DPI?

Most digital images default to 72 DPI (Mac) or 96 DPI (Windows) because they're optimized for screen display. This doesn't mean low quality - pixel dimensions determine screen quality, not DPI.

What DPI do I need for printing?

For professional printing, use 300 DPI. For casual home printing, 150-200 DPI is usually sufficient. Large format prints (posters, banners) can use lower DPI since they're viewed from a distance.

Can I change the DPI of my image?

Yes, but it's important to understand that simply changing the DPI metadata won't improve image quality. To maintain quality when increasing DPI for print, you need to either keep the same pixel dimensions (resulting in a smaller print size) or use proper image editing software to upscale.

Is my image uploaded to your servers?

No. This tool processes images entirely in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
