Image Cropper

v1.0.0·Added in 1.0.0

Crop a photo before upload: aspect presets, pinch or wheel zoom, fine and 90° rotation, a thirds grid and a sized JPEG, PNG or WebP export.

Drag the photo with a finger or the mouse to move it under the frame; pinch with two fingers or turn the mouse wheel to zoom, and the image always keeps covering the frame. While you move it a rule-of-thirds grid fades in and a small pill on the stage shows the zoom and the angle; a first-run hint says how to move and zoom and disappears after the first touch. Pick a ratio (Free, 1:1, 4:3, 3:4, 16:9, 9:16) from the segmented switch on wide layouts or the scrolling chip rail on phones, where every chip is a 44px target. In Free mode the frame starts at the photo's own ratio and its four corner brackets resize it with a drag (the frame stays centered). The zoom row has minus and plus buttons that glide the zoom on a short tween around a slider; the rotation row has a 90° left turn that animates, a slider from −45° to 45° with a center mark for straightening, and an optional horizontal flip that turns like a card. Reset puts position, zoom, rotation and flip back. Tab to the crop frame (it shows a white focus ring): arrow keys move the photo by 10px (Shift+arrows by 2px for fine nudges), + and − zoom, r turns 90° left, f flips when flippable, 0 resets and Escape cancels a corner drag. The sliders take arrows, Home and End, and read their value as 150% or −12°; aspect changes, turns, flips and resets are announced. On phones the stage caps at 60% of the screen height and the toolbar stacks. The export crops in a canvas with the rotation and flip, steps down large photos in halves for a sharp result, and can mask a circle with transparent corners.
