Pixel Position & Color Picker Downloads & RevenuePixel Position & Color Picker · App Store

An image measuring app: tap a photo to read that point's coordinates, color, and the distance between two points as numbers.

Replace eyeballing with pixel-level numbers. Images open straight from your photo library, so you can measure screenshots and camera photos right away.

■ GREAT FOR • Checking margins and misalignment in app or web screenshots, down to the pixel • Comparing a design mockup with the built screen and confirming position differences in numbers • Looking up color codes in an image for documents or designs • Quickly checking the contrast ratio between text and background colors • Finding tap coordinates for automation tools and scripts • Recording positions and distances in photos for experiments, observation, or image analysis prep

■ WHAT YOU CAN MEASURE • Coordinates: pixel coordinates (X, Y) of the tapped point • Color: choose two formats from HEX, RGB, HSB (HSV), and HSL. Long-press to copy • Delta: horizontal (ΔX) and vertical (ΔY) difference between points A and B • Distance: straight-line distance between two points • Contrast ratio: calculated from the colors of points A and B (using the WCAG formula) • Relative position: shown as a proportion of the whole image, from 0 to 1 • Radius circles: draw a circle of any radius around each point

■ HIT THE EXACT PIXEL • Pinch to zoom up to 8×, drag to pan • Pixel magnifier and crosshair show what's under your finger as you place a point • Enter coordinates as numbers to place points exactly • Fine-tune with sliders, or move one pixel at a time with direction buttons • Set ΔX, ΔY, or distance to move the other point • Lock a point to keep your reference fixed while measuring • Undo and redo point moves • Operate all sliders with multiple fingers at once

■ MAKE IT YOURS • Set the origin (0, 0) to the top left, top right, bottom left, or bottom right • Hide color information for a clean coordinates-only view • Toggle the magnifier, its range, and the radius controls • Light, Dark, or System appearance • Available in 9 languages, switchable inside the app

■ SHARE RESULTS Export an annotated image with your lines and circles. Include the coordinate panel to send the numbers in the same image.

■ LARGE PHOTOS AND PRIVACY • High-resolution photos display smoothly, with coordinates shown in original image pixels • iCloud photos load automatically for measuring • Works with limited photo access, showing only the photos you allow • Measurement happens on your device; photos are not sent to the developer's servers Note: For images over 4096 pixels on the long side, colors are approximated from a reduced image (the app shows a notice).

■ FREE Core tools, including coordinate, color, distance, and delta measurement, the magnifier, origin selection, radius circles, and sharing, stay free with no usage limits. On the free tier, ads appear on screens such as the photo list and Settings. The screen where you measure images shows no ads, so you can stay focused.
