Progressive Web App (PWA)

Install this tool as a standalone application on your Desktop, Android, or iOS device. Access it anytime, even without an internet connection.

Real Header Metadata Inspection

Universal Compatibility

Works seamlessly across Windows, macOS, Linux, ChromeOS, iOS Safari, and Android Chrome without installing any drivers or plugins.

Check Image DPI Before Sending to Print

Commercial printers and publishing houses reject artwork that fails to meet 300 DPI print standards. The Image DPI Checker reads the embedded resolution metadata in your JPEG, PNG, or TIFF files and tells you exactly how large it can be printed cleanly.

Frequently Asked Questions

Got questions about converting Image to Output? Find answers below.

Pixels measure total digital image data (e.g., 3000x2000 px). DPI (dots per inch) specifies how densely those pixels will be laid down on physical paper. A 3000x2000 px image printed at 300 DPI produces a crisp 10x6.6 inch photograph.
