Image Pixel Info
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.
How to Use
- 1Click the upload area or drag & drop an image file (PNG, JPG, or WebP).
- 2The tool automatically reads the file and displays width, height, file size, and colour mode in real time.
- 3Check the DPI value – if the image contains EXIF or pHYs metadata, the resolution will be shown; otherwise it will display “Not available”.

Frequently Asked Questions
How do you determine the colour mode?
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”.
Why does DPI show ‘Not available’ for some images?
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.
Is my image uploaded to a server?
No. All analysis runs entirely inside your browser. No file data is ever sent over the network.
