✂️ Image Cropper — Free, Offline, In-Browser

Toolio's Image Cropper lets you drag a crop box over any image, lock it to a preset aspect ratio (Free, 1:1, 4:3, 3:2, 16:9, 9:16), and download the cropped result — all free, entirely in your browser, with no file uploads or login required.

About

The Image Cropper runs entirely in your browser using the HTML5 Canvas API — your image never leaves your device. You can drag the crop handles at any of the 8 anchor points, move the selection freely, or draw a brand-new crop area from scratch. Preset aspect ratios snap the crop box automatically so you always get pixel-perfect dimensions for social media thumbnails, profile photos, or print layouts. Because everything is processed client-side, the tool works offline, on any OS, with no data collected and no account needed.

How to use

  1. Drop an image onto the canvas area or click to open a file from your device (PNG, JPG, GIF, WebP, or BMP).
  2. Choose an aspect ratio preset at the top — Free, 1:1, 4:3, 3:2, 16:9, or 9:16 — or skip to use a freehand crop.
  3. Drag the 8 edge or corner handles to resize the crop box, or drag inside the box to reposition it. Draw a new area by dragging outside the current selection.
  4. Click the "Crop" button to apply the selection. A live preview of the cropped area and its pixel dimensions will appear below.
  5. Click "Download" to save the cropped image as a PNG file directly to your device.
