What can it do?


Pan and zoom to view the details of your image. The mouse cursor includes highly visible crosshairs that bracket the pixel under the cursor, as well as that pixel's row and column.


Right-click-and-drag to create a sticky selection with offset and size information. Hold down Ctrl while drawing the selection to snap the selection to horizontal, vertical, or square. Edit the selection with the right mouse button.

Eye-Drop / Probe Log

Every click on the image logs the color, pixel position, and the properties of any current selection. You can format these log entries in a number of useful ways and copy them individually or in a list.

Custom formatters can use any combination of the following properties:

  • Pixel color (RGBA, HSV, HSL, and grayscale)
  • Click position (floating point and integer)
  • Image width and height
  • Selection bounds and size
  • Mean and median RGBA values of the selection
  • The start and end points (floating point and integer) of the selection profile line
All quantities can be formatted as integer, decimal (floating point), or hexadecimal.

Generate palettes from images

The click log can easily be used to generate a palette from an image. Just click on colors you like, delete any log entries you don't want, and copy the result to the clipboard in your chosen format.

Extract Colors

Paste a body of text or HTML into the Click Log and it will automatically extract all the colors present in the text. Then use the Click Log's copy feature to get back a clean list of those colors, formatted per your custom formatter


Crop the image to your selection. Just select an area and hit Enter.


Delete the contents of your selection. Just select an area and hit the Delete key. Useful if you want to share a screen shot, but avoid sharing sensitive information.

Download / Save

After cropping or redacting, you can download the resulting image to your computer.


When you make a selection, there's a red dashed trace line shown in the selection. The pixel values and RGB channels along that line are shown in a separate cross-section display that allows you to see precisely how they vary.

Selection histogram

When you make a selection, there's an RGB histogram shown of those specific pixels.


Load up any number of images and flip between them.

Image diffing

When you load up multiple images with the same dimensions, the view state is preserved when flipping between them. This allows you to detect subtle differences between them, which is especially useful when zoomed in.

Compress or Fix Noise

Click the ellipsis menu on each image record to access options to send your image to our companion services, Recompressor.com and PixFix.com.
