Analyze image file properties instantly. Get dimensions (width × height), the exact file size, colour mode (grayscale or RGB), and DPI (dots per inch) when the metadata is present. Supports PNG, JPG, and WebP images – all processing happens locally, so your files never leave your device.
The image is drawn onto an off‑screen canvas, and a fast sample of its pixels is examined. If every sampled pixel has equal red, green, and blue values, the mode is reported as “Grayscale”; otherwise it is “RGB Colour”.
DPI depends on embedded metadata. Many JPEGs store it in EXIF, and many PNGs store it in the pHYs chunk, but not all images include this information. The tool reads whatever is available and displays “Not available” if nothing is found.
No. All analysis runs entirely inside your browser. No file data is ever sent over the network.
