Profile pictures need a square crop, video covers often use 16:9, and phone wallpapers use a portrait layout. The image cropper provides common aspect ratios and downloads the result directly from your browser. Your image is not uploaded.

Available controls

• Aspect Ratio：Custom, 16:9, 4:3, 1:1, 3:4, and 9:16.
• Drag Mode：adjust the crop selection or move the underlying image.
• Zoom：zoom in or out to position the crop.
• Rotate：turn the image 90° left or right.
• Flip：mirror horizontally or flip vertically.
• Lock：prevent accidental movement of the image and selection.

How to crop an image

1. Open Image Cropper and select or drag in an image.
2. Choose an Aspect Ratio, or keep Custom for a freeform crop.
3. Drag the selection corners to resize it and drag inside it to reposition it. Switch Drag Mode when you need to move the image instead.
4. Use the rotation or flip controls if needed.
5. Choose an output format and click Crop at the top right. The cropped image downloads automatically.

Aspect ratios for common uses

• Profile pictures and product thumbnails: 1:1.
• Video covers, landscape banners, and presentation images: 16:9.
• Traditional photos and document illustrations: 4:3.
• Phone wallpapers and vertical video covers: 9:16.
• Portrait posters and social media images: 3:4.

Choosing an output format

• Original file format: requests the source image format.
• PNG: lossless and supports transparency; useful for icons and screenshots.
• JPG: useful for photographs; transparent areas become white.

WebP：often offers smaller files at comparable quality for website images.

If your browser cannot export the selected format, the tool falls back to PNG and shows a notice. The filename extension follows the actual output format.

Output dimensions

The maximum output width and height are 4096 pixels. Larger selections are scaled down proportionally. Ordinary photos and screenshots often fit within this limit, but a very large panorama may export at fewer pixels than the original selected area.

Practical tips

• Crop before compressing：remove unnecessary areas, then use Image Compression.
• Change a portrait's proportions：start with a rough Custom crop, then switch to the target ratio for fine adjustments.
• Correct orientation：use the 90° rotation controls for sideways images. Small-angle straightening requires another editor.

Frequently asked questions

What will the downloaded file be called?

The original name is retained, with the extension changed to match the output format.

Can I use it on a phone?

You can open it in a mobile browser, but precise crop adjustments are easier on a computer.
