How to Use the Image Cropper to Crop a Picture Online
Cropping removes unwanted edges and focuses attention on a subject. This image cropper uses pixel coordinates, so preview the image and keep the crop rectangle inside its original dimensions.
Select the area to keep
- Choose an image and wait for the preview to appear.
- Drag the box on the picture to move it, and drag its corners and edges to resize it. Use Draw new selection to start again, or Select whole image.
- If you need exact numbers, open Enter exact values and type the position and size in pixels.
- Start the crop and check the edges of the downloaded picture.
- Adjust the box and try again if an important detail was cut off.
Understanding X, Y, width and height
X and Y are the left and top edge of the box in pixels, counted from the top-left corner of the picture. The width and height are the size of the area to keep. Dragging the box fills these numbers for you, and the box must stay inside the picture.
Prepare images for a destination
Different profile, product and document layouts may use different aspect ratios. Check the target service dimensions before cropping; this tool does not automatically infer a platform-specific frame.
Using the selection box
After the picture appears, a box shows the area that will be kept. Drag inside the box to move it and drag its corners or edges to resize it. Draw new selection starts a fresh box, which is useful on a phone, and Select whole image puts the box around everything. Press the crop button when the box is where you want it, then look at the edges of the saved picture.
Exact numbers when you need them
Open Enter exact values to see or type the position and size of the box in pixels. X and Y are the left and top edge of the box, counted from the top-left corner of the picture, and the width and height are the size of the area to keep. The numbers and the box follow each other. For a square use the same width and height, and for a 3 by 4 shape use a width and height in that ratio, such as 600 by 800.
After cropping
Cropping creates a new file and leaves your original as it is. If the form or website asks for a particular pixel size, crop first for the right shape and then use Image Resizer to set the size, or use the optional Crop first step inside Image Resizer. Keep the original, because cropped-away parts cannot be brought back from the new file.
Frequently asked questions
Why does the crop fail?
The selected rectangle may start outside the image, have zero size or extend beyond the source dimensions. Reduce or reposition the crop values.
Can I restore cropped edges later?
The downloaded image contains the crop result only. Keep the original if you may need a different crop.
How do I crop a square?
Drag the box and make the width and height the same in Enter exact values.
Can I undo a crop?
Not from the cropped file. Use your original and crop again.
