Image Info

Choose an image, drop it, or paste it. The file stays on your device. Load controls stay available in every view. Copy preview copies the analyzed image, with a longest side of at most 600 pixels.

In the Image view, point, tap, or enter X/Y to inspect an original decoded pixel. Coordinates start at zero in the top-left corner. Arrow keys on the preview move one pixel; Shift moves ten and Home selects (0, 0). The magnifier outlines the selected pixel. RGBA and eight-digit HEX include alpha.

RGB includes an alpha channel when transparency is present. HSV hue uses degrees; saturation and value use percent in the pixel readout. Gray has no defined hue: the pixel readout shows —, its hue image stays gray, and the hue histogram includes only chromatic pixels. YCbCr follows full-range JFIF rounding and clipping, with neutral Cb/Cr at 128. These are converted values from the browser’s decoded RGB, not the original compressed components.

Channel histograms and scopes analyze the preview, reduced to a longest side of 600 pixels when necessary. Percentages are fractions of analyzed pixels, not fractions of the tallest bar. Fully transparent pixels are excluded from color histograms and scopes; the alpha histogram includes every pixel. Partly transparent colors count once. The luma histogram and waveform use BT.709 weights on decoded RGB; this is luma, not linear-light luminance. Vectorscope targets use the same JFIF Cb/Cr conversion as its points.

Headers show bounded structural entries for PNG/JPEG/WebP and top-level ISO BMFF boxes; GIF shows only the header and logical screen descriptor. At most 512 entries are listed. This is not a complete format, CRC or metadata validator. Use the EXIF tool for camera metadata.

Limits: 50 MiB per file and 40 million decoded pixels. Browser-supported formats only; animated files show one decoded frame. Browser color management, orientation and 8-bit canvas conversion affect displayed pixels. Encoded dimensions are shown separately when orientation changes them. Pixel-count checks cannot guarantee the browser decoder’s memory use. Files are not retained after leaving the tool.
