Online Image Cropper

Drag the corner and edge handles to size your crop freely, just like the iPhone Photos app, or drag inside the box to move it. Lock a ratio such as 1:1, 4:3 or 16:9 when you need a fixed shape, and rotate or flip before you export. It works on touchscreens, and the cropped result is generated right in your browser — nothing is uploaded.

Why use Crop Image?

Crop Image lets you edit and optimise images in seconds, right in your browser — no bulky software to install and nothing uploaded to a server.

  • 100% private: files are processed in your browser and never uploaded.
  • Completely free, with no account, no watermarks and no usage limits.
  • JPEG, PNG, WebP
  • Drop or select the image you want to crop.
  • Works on desktop, tablet and phone. Form controls support keyboard navigation, while crop-area adjustment uses mouse or touch dragging.

What it can do — and its limits

  • Free-form cropping with draggable corner and edge handles, like the iPhone crop tool.
  • Optional locked aspect ratios, plus 90° rotation and horizontal/vertical flip.
  • Exports to PNG, JPG or WebP entirely in your browser — no upload.

How to use Crop Image

  1. Drop or select the image you want to crop.
  2. Drag the corner or edge handles to set the crop area freely, or drag inside the box to reposition it.
  3. Optionally lock an aspect ratio (1:1, 16:9…) or rotate and flip the image.
  4. Check the pixel dimensions of your selection, pick a format, then download the cropped result.

Examples

  • Cropping a portrait into a perfect square for a profile picture.
  • Trimming a screenshot to a clean 16:9 frame.

Supported formats & limits

  • JPEG, PNG, WebP

Limitations

  • Cropping reduces resolution — the output is only as large as the area you keep.
  • Rotating by arbitrary angles may add transparent or filled corners depending on output format.

Frequently asked questions

Does crop work on my phone?

Yes. The crop handles and zoom are designed for touch, so you can crop comfortably on mobile.

Can I crop to a specific ratio?

Use a preset like 1:1, 4:3, 16:9, 3:2 or portrait, or crop freely.

Does cropping reduce the file size?

Usually yes, because you keep fewer pixels — though the exact size depends on the output format and quality.
