Crop an image
Drag the crop box over your picture, or lock it to a common ratio. Download the cropped result in its original format.
Files never leave your deviceHow to crop an image
- Drop an image onto the box above, or choose one from your device.
- A crop box appears over your picture. Drag inside it to move it, and drag the round handles on the corners and edges to resize it.
- For a specific shape, pick an Aspect ratio such as 1:1, 4:3 or 16:9. The box keeps that ratio while you resize it. Choose Free to move each edge independently.
- For precision, type exact values for left, top, width and height in pixels.
- Press Crop image and download the result.
With the keyboard, focus the crop area, then use the arrow keys to move it. Hold Shift for bigger steps or Alt to resize instead of move.
Cropping stays on your device
The picture is shown straight from your own computer or phone. When you press the button, a background worker cuts the selected area out and encodes the new file. No upload takes place, so private photos and screenshots with sensitive details remain with you.
Getting the crop right
Ratios matter because every place that shows pictures has its own shape. Square 1:1 suits profile photos and many feeds. 4:5 is a tall portrait format for Instagram. 16:9 matches video thumbnails and presentation slides, while 3:2 is the shape of most camera sensors and 4:3 that of many tablets and phones. 9:16 fits stories and vertical video.
When you need a particular pixel size as well as a ratio, crop first and then use the resize tool. Cropping removes pixels, and resizing afterwards scales what is left.
Good to know
- The file is saved in its original format. JPG, WebP and AVIF crops are encoded once more at high quality, so repeated crops of the same file slowly lose detail. Crop from the original when you can.
- Pixels inside the box are not scaled, so the output size equals the size shown in the width and height boxes.
- Photos with a rotation tag are cropped as you see them, and the result is saved upright.
- Metadata such as GPS location and camera information is not included in the cropped file.
- Cropping handles one image at a time, because each picture needs its own box. For many pictures at once, the resize tool with a preset can crop to a ratio automatically.
Frequently asked questions
How do I crop to an exact ratio?
Pick a ratio such as 1:1, 4:3 or 16:9 and the crop box keeps that shape while you drag and resize it.
Can I crop several images at once?
Crop one image at a time so you can position each box. To change many images at once use the resize tool.
Does cropping change quality?
Pixels inside the crop are kept as they are. The file is saved again in the same format, so lossy formats get one extra encoding pass.
Are my files uploaded anywhere? How can I check?
No. The image cropper runs entirely in your browser using JavaScript and WebAssembly, so your files never leave your device. You can verify it: open your browser's DevTools (F12, or Cmd+Option+I on a Mac), switch to the Network tab, tick "Preserve log", clear the list and process a file. You will only see requests for this site's own static files, never one that carries your data. You can also turn on "Offline" in the Network tab (or disconnect from the internet) once the page has loaded, and the tool keeps working.
Does it work offline?
Yes. After your first visit a service worker saves the tool to your device, so it opens and works without a connection. Only advertising needs the internet; the processing never does.
