About the Image Cropper

The Image Cropper cuts away the parts of a picture you do not need. Adjust a selection on the image, choose a fixed aspect ratio such as 1:1 for profile pictures or 16:9 for video thumbnails, and download just the selected area at the full resolution of the original.

The selection can be moved and resized with a mouse, a finger or a pen, set precisely with the X, Y, Width and Height fields, or nudged pixel by pixel with the arrow keys. The values always refer to the pixels of the original image, not to the size shown on screen.

The image is cropped in your browser and never uploaded to a server.

How to use it

  1. Click "Choose an image", drop a file onto the box or paste an image from the clipboard.
  2. Pick an aspect ratio: Free, Original, 1:1, 4:3, 3:2, 16:9 or 9:16.
  3. Drag inside the selection to move it, drag one of the eight handles to resize it, or drag across the image to draw a new selection.
  4. For exact values, type X, Y, Width and Height in original-image pixels.
  5. Choose the output format and quality, then click "Crop image".
  6. Check the preview and the file size of the result and click Download.

Features

  • Works with mouse, touch and pen: Move the selection or resize it with eight handles. Dragging on the image does not scroll the page, so it is easy to use on phones and tablets.
  • Aspect ratio presets: Free, the original ratio of the image, 1:1, 4:3, 3:2, 16:9 and 9:16. The chosen ratio is kept while you move the handles.
  • Pixel-exact inputs: X, Y, Width and Height are in original-image pixels and stay in sync with the selection. Values are limited so the selection always stays inside the image.
  • Keyboard control: Focus the selection and use the arrow keys to move it by 1 pixel, or by 10 pixels with Shift. Hold Alt (Option on Mac) to change the width and height instead.
  • Full-resolution output: The crop is taken from the original image, not from the smaller preview, and the selected pixels are not resampled.

Examples

Square profile photo

Choose 1:1, drag the square over the face and make it bigger or smaller with a corner handle. If the site needs a specific size such as 400 × 400 pixels, resize the cropped image afterwards with the Image Resizer.

Removing a distracting edge

With Free selected, drag the left handle inwards to cut a stranger off the edge of a group photo while keeping the rest of the picture unchanged.

An exact region of a screenshot

Type X 0, Y 120, Width 1280 and Height 600 to cut a precise strip out of a 1280-pixel-wide screenshot, for example to share only one part of a web page. Save it as PNG to keep text sharp.

Limitations and notes

  • Cropping re-encodes the image. JPG and WebP output is lossy (quality 92 by default), so cropping a JPG is not lossless; choose PNG for lossless output at a larger file size.
  • EXIF metadata such as camera details and GPS location is removed, and colour profiles may be converted to sRGB.
  • Only rectangular crops are possible – no free rotation, circles or other shapes. Use Rotate & Flip Image for 90° turns.
  • With a fixed ratio the result can differ from the exact ratio by up to one pixel, because sizes are whole pixels.
  • On a large image shown on a small screen, dragging moves the selection in steps of several original pixels; use the number fields or arrow keys for pixel precision.
  • Animated images keep only their first frame, and AVIF files need a browser that can decode AVIF.

Frequently asked questions

Does cropping reduce the image quality?

The pixels inside the selection are copied without scaling. Saving as JPG or WebP compresses them again, which loses a little detail; at the default quality of 92 the difference is very hard to see. Choose PNG if you need a lossless result.

How do I crop an image to a square?

Select the 1:1 aspect ratio. The selection becomes a square that keeps its shape while you move or resize it. Position it and click "Crop image".

Can I crop to an exact size in pixels?

Yes. Type the width and height into the number fields – with a fixed ratio the other value is adjusted automatically. To get a smaller final size, such as 1080 × 1080 from a larger square, crop first and then use the Image Resizer.

Does it work on my phone?

Yes. Drag the selection or its handles with your finger. While your finger is on the image the page does not scroll, so use the area around the image to scroll.

Is my photo uploaded?

No. The photo is opened and cropped by your browser on your device, and the result is saved directly from there.
