No. The Image Aspect Ratio Detector processes your image entirely in your browser using JavaScript. Your file never leaves your device, and no data is sent to our servers.
The Screen Resolution Checker reads your browser viewport and device pixel ratio. Results are accurate for your current display settings. Note that browser zoom level and display scaling can affect reported values.
DPI (dots per inch) refers to printer output resolution, while PPI (pixels per inch) refers to screen pixel density. In practice, both terms are often used interchangeably. Our calculator handles both use cases.
