Crop an image in your browser

What this tool does
The tool cuts a rectangle out of one picture and writes it in the format of the original. You mark the area by dragging on the preview or by typing its position and size in pixels. Fixed proportions, for example a square for a profile picture, keep the width and height in step.
How to use it
- Choose a picture, or drop it on the marked area. A preview appears.
- Choose the proportions, or leave them free.
- Drag on the preview from one corner of the wanted area to the opposite corner. The four fields follow.
- Adjust the fields if you need exact values.
- Start, then download the result.
Everything can be done with the keyboard alone: the fields for left edge, top edge, width and height define the area completely, and dragging is only a quicker way to fill them.
How the area is defined
All values are pixels of the original picture, not of the preview, which is usually shown smaller. The left edge and the top edge are the distance of the area from the left and the top of the picture, starting at 0. The area must end inside the picture: left edge plus width may not exceed the width of the picture, and the same holds for the height.
With fixed proportions, choosing them selects the largest area with these proportions in the middle of the picture. When you then change the width, the height is calculated, and the other way round. If the area would reach beyond the picture, both values are reduced together.
The pixels inside the area are copied without scaling. JPG and WebP results are written with quality 92, PNG results without loss. Metadata of the original is not copied.
Worked example
A photo has 4000 × 3000 pixels and should become a square profile picture. Choosing Square (1:1) selects the largest square in the middle: the side is the smaller dimension, 3000 pixels. The left edge is (4000 − 3000) ÷ 2 = 500, the top edge is 0.
For 16:9 the full width of 4000 pixels is used. The height is 4000 × 9 ÷ 16 = 2250 pixels, and the top edge is (3000 − 2250) ÷ 2 = 375.
Common mistakes
- Cropping when a smaller picture is wanted. Cropping removes parts of the picture; to keep everything at a smaller size, use the resize tool.
- Cropping very tightly and enlarging afterwards. The cut-out has only the pixels that were inside the area.
- Cropping a JPG several times in a row. Each run writes the picture again with loss. Crop once from the original.
Frequently asked questions
- Is my picture uploaded for the preview?
- No. The preview shows the file straight from your device through a temporary address that exists only in this browser tab, and it is released when you choose another picture or leave the page. The crop itself is also done in your browser. When advertising is enabled and permitted, the page also loads third-party advertising scripts; the privacy policy explains this.
- Can I crop several pictures at once?
- No. The area is chosen for one picture at a time. Choosing another picture replaces the current one.
- Why is the photo shown upright although the file is stored sideways?
- Cameras often store the picture as the sensor saw it, together with a note on how to turn it. Your browser applies this note, and the tool crops the picture the way it is displayed.
- Does cropping reduce the quality?
- For PNG it does not. JPG and WebP are written again with quality 92, which removes a little detail, as every lossy save does.
- Can I crop to a circle or another shape?
- No. The area is always a rectangle.
