Is this image analyzer free?
Yes. This image analyzer is completely free with no sign-up or limits on how many images you inspect.
Does it upload my image to a server?
No. The image is analyzed entirely in your browser, so it stays private on your device and is never uploaded.
Does it edit or change the image?
No. This page is inspection only. It reads the image properties and does not alter or re-save the source image.
How does it find the dominant colors?
It samples the rasterized image in the browser to surface a preview of the dominant colors, giving you a quick read on the palette.
What details does it report?
It reports file size, pixel dimensions, aspect ratio, whether transparency is present, and a preview of the dominant colors.
Why does my logo's palette come back mostly white or grey?
Because the palette is built from every pixel in the file, weighted by how often each color occurs. On a logo sitting in a large empty canvas, the background is the majority of the pixels and dominates the result. Crop tightly to the artwork and re-run it, and the brand colors move to the front.
How do I find out the camera and location instead?
Use the EXIF and GPS viewer, which reads the metadata block of a JPG or HEIC and reports make, model, lens, ISO, shutter, aperture, capture date, and GPS coordinates. This analyzer deliberately looks at the decoded bitmap and the file entry only, which is why it works on PNG, WebP, GIF, and BMP too.
What counts as transparency here?
Any pixel with an alpha value below 255. The check walks the whole decoded bitmap, so a single pixel of soft antialiasing on the edge of an icon is enough to flip the answer to Detected. That is the right behaviour if the question is whether the file is safe to flatten onto a colored background.
Can I use this to decide whether an image is web-ready?
It gives you the three numbers that decide it. Dimensions tell you whether it is oversized for its slot, file size tells you what it costs to download, and the ratio tells you whether it will be cropped by a fixed container. Anything wider than about 2000px or heavier than a few hundred kilobytes for a content image is worth passing through the compressor.
Does the file get uploaded to check it?
No. The image is decoded to a canvas in the page and read back as pixels on your device, which is why it works on a private mockup or an unreleased screenshot with no risk. The one network call is a credit counter that carries the tool name and no file data.
