Crop an image
This free tool crops a JPG, PNG, WebP, GIF, BMP or AVIF image to the area you mark, either by dragging a box on the picture or by typing the position and size in pixels, with optional fixed shapes such as 1:1, 4:3 and 16:9. Cropping runs in your browser and the image is not uploaded. It handles one image at a time, a JPG is saved again at 92 % quality, and camera details are removed.

Why crop an image
Cropping cuts away the parts of a picture you do not want: the edge of a messy desk around a document photo, a stranger at the side of a holiday snap, the taskbar under a screenshot, or the empty space around a logo. It is also the way to give an image the shape a site asks for, such as a square profile picture or a 16:9 thumbnail for a video. Open an image, drag a box over the part to keep, move it into place, and download the cropped copy. The numbers next to the picture show exactly which pixels are kept, and you can type them to get a precise result. The image is read and cropped by your browser on your own device, so a photo of an ID card or a screenshot of a bank statement never leaves it.
How to crop an image
- Drop an image in the box, or click to choose it. JPG, PNG, WebP, GIF, BMP and AVIF are accepted.
- Drag on the picture to mark the area to keep, or type its left and top position, width and height. Choose a shape such as 1:1 if you need one.
- Click Crop image and download the result.
What to know about cropping
Fixed shapes
With a shape such as 1:1 or 16:9 chosen, the box keeps that proportion while you drag, and choosing the shape gives you the largest box of that shape in the middle of the picture. Typing a width then sets the height for you, and the other way round. Free lets you draw any rectangle.
Exact pixel numbers
Left and top count from the top-left corner of the picture as it is shown, starting at 0. A photo taken with the phone held upright is turned upright first, so the numbers always match what you see. The box can never reach outside the picture; values that would are shortened to fit.
Which format comes out
The cropped image keeps its format where the browser can write it. A JPG is saved again as a JPG at 92 % quality, which is hard to tell apart from the original; PNG stays lossless with its transparency; WebP stays WebP in Chrome, Edge and Firefox, while Safari, which cannot write WebP, saves a PNG and says so. GIF and BMP become PNG, with only the first frame of an animated GIF, and AVIF becomes JPG.
Cropping does not shrink the picture
The pixels you keep stay at their original size, so a crop from a large photo can still be large. To get a smaller width as well, resize the cropped image afterwards.
Camera details are removed
The new file contains only the picture: the date, camera model and GPS position of a phone photo are not copied. Make sure the crop has really removed what you wanted hidden; nothing outside the box is kept in the file.
About the formats
JPG
JPG (or JPEG) is the most widely used image format for photos, supported by every camera, phone, browser and image editor. It uses lossy compression, which keeps files small at a small cost in quality.
- Best for photos; text and sharp lines can get blurry edges.
- No transparency: transparent areas become a solid colour.
- The quality setting trades file size against detail.
PNG
PNG (Portable Network Graphics) is a lossless image format from 1996 and the usual format for screenshots, logos, diagrams and images with transparency. Every pixel is stored exactly, so text and sharp edges stay crisp.
- Lossless: saving again never reduces quality.
- Supports full transparency (an alpha channel).
- Photos saved as PNG are usually several times larger than as JPG.
Frequently asked questions
Is my image uploaded?
No. The image is cropped by your browser on your own device and is never sent anywhere.
How do I crop a picture into a square?
Choose 1:1 (square) as the shape. The largest square in the middle of the picture is marked at once; drag inside it to move it, or drag on the picture to draw a smaller square.
Can I crop several images at once?
This tool crops one image at a time, because every picture needs its own box. To cut many images to the same width, use the resize tool instead.
Can I undo a crop?
Your original file is not changed. The cropped copy is a new file with _cropped added to its name, for example photo_cropped.jpg, so you can always start again from the original.
Does it work on a phone?
Yes. Drag with your finger on the picture to draw the box, or type the numbers if the picture is small on your screen.
