How to use it
- Click Choose files or drop a picture on the box. You can also paste one with Ctrl+V.
- If the picture is sideways, click Turn left, Turn right, or a flip button.
- Pick an Aspect ratio, or leave it on Free. Drag the box to place it, and its corners or edges to resize it.
- For exact figures, type the Left, Top, Width and Height in pixels.
- Click Crop image and download the result.
Moving and resizing the box
Drag inside the box to move it, and drag a corner or an edge to resize it. With a ratio chosen, a corner keeps the ratio while you drag it, and an edge sets the other side from the ratio. The box never leaves the picture. With the keyboard, Tab to the box, then use the arrow keys to move it and Shift with an arrow key to change its size.
Turning and flipping first
A photo taken with a phone held sideways is turned when the browser reads its orientation, so it usually shows the right way up. If it does not, turn or flip it here. The crop is cut from the turned picture, and the box goes back to the whole picture when you turn or flip it.
Circle crops
A circle crop uses a square area and clips it to a circle. The corners outside the circle are transparent, which a JPEG cannot store, so the result is always a PNG. Use it for profile pictures and round logos.
Example: a 16:9 header from a 4000 × 3000 photo
Choose the 16:9 ratio on a 4000 × 3000 pixel photo. The largest box with that shape is 4000 pixels wide and 2250 pixels high, placed 375 pixels from the top, so the top and bottom bands are removed evenly.
The result is a 4000 × 2250 pixel picture, the right shape for a website header, and the file name ends in -cropped.
Frequently asked questions
Is my photo uploaded when I crop it?
No. The crop is cut from the picture in your browser, on your own device. You can check by turning off your internet connection after the page has loaded and cropping a picture.
Does cropping lower the quality of the picture?
Cutting out part of a picture does not change the pixels that remain. A JPEG is written again, at a high quality, so a crop of a JPEG is a little different from the original, but the difference is small at this quality.
How do I make a round profile picture?
Tick Circle crop. The box becomes a square, and the picture is clipped to a circle with transparent corners. The result is a PNG, so it can be placed on any background.
Why does the box jump back to the whole picture when I turn it?
Turning or flipping changes the shape of the picture, so the box is set again to the whole picture, or to the ratio you chose. Draw or type the box again after you turn the picture.
Can I crop a picture to an exact number of pixels?
Yes. Type the Left, Top, Width and Height in pixels. The box is kept inside the picture, so a value that goes past its edge is brought back to the edge.
