Crop an Image to the Best Composition
Choosing the part of the picture to keep
Select the part of an image you want to keep and adjust the crop visually. Use a preset aspect ratio for a square avatar or portrait cover, or enter a custom crop around the subject. Everything outside the selection is removed from the result. Check faces, text and important edges before exporting; use Resize Image afterward if the destination also requires exact pixel dimensions.
Cost: Free to use. File size and usage limits apply.
How to crop an image
Upload one image
Click Upload an image to crop or drop a file onto the preview, up to 200 MB. Images you uploaded or created in other tools are listed under Files. The line under the preview shows the size, for example
4032x3024px.Place the crop box
The box starts centred at 70% of the width and height. Drag inside it to move it, drag one of the eight handles to resize it, or press outside it and drag to draw a new one. The dimmed area is removed.
Fine-tune the numbers
Under Crop, X and Y set the top-left corner and W and H the size, all in px. When the box has keyboard focus, the arrow keys move it by 1 px, or 10 px with Shift.
Crop and download
Click Crop Image!. The preview then shows the result with a slider to compare it with the original. Click Download to save it, or Clear result to return to the original with the same box and adjust it. The result is also added to Files for other image tools.
Crop settings
The examples use a 4000 × 3000 px photo.
- Freeform
- The default. Width and height change independently.
- Square
- Sets the largest centred square: 3000 × 3000 px at
X 500,Y 0. While Square is selected, the box stays square: dragging any handle or typing a new W or H changes both sides together. - Circle
- Starts with the same square, and the preview shows the circle inside the box. In the result, everything outside the circle becomes transparent. The box stays square while you change its size. JPG and BMP cannot store transparency, so their circle crops are saved as PNG; GIFs are cut to the circle frame by frame.
- X and Y
- The top-left corner of the box in px, measured from the top-left corner of the image. The box always stays inside the image, so X can go up to the image width minus W and Y up to the height minus H. Moving the box with the arrow keys stops at the edge.
- W and H
- The size of the result in px; nothing is scaled. The minimum is 1 px when typed and 8 px when dragging, the maximum is the image width minus X or the height minus Y.
- Full image
- Resets the box to the whole image. Useful when only one edge needs trimming: start here and drag that edge's handle inwards.
- Center (1:1)
- Sets the same centred square as Square without changing the selected shape.
- 80% (Inset)
- Trims 10% from every edge and keeps the aspect ratio: 3200 × 2400 px at
X 400,Y 300. A quick way to cut off a border.
Cropping to 16:9, 4:5 or another exact ratio
Apart from the square there is no ratio lock, so you calculate the box once and type it in. Keep one side at full length and derive the other from the ratio.
From a 4000 × 3000 px photo to 16:9: keep the full width, so H = 4000 × 9 ÷ 16 = 2250 px, and centre it with Y = (3000 − 2250) ÷ 2 = 375. Enter X 0, Y 375, W 4000, H 2250, then drag the box up or down to place the horizon; dragging does not change its size. For a 4:5 portrait of the same photo, keep the full height: W = 3000 × 4 ÷ 5 = 2400 px and X = 800.
If the destination also needs an exact pixel size, such as 1080 × 1350 px for that 4:5 crop, crop first and then scale the result with Resize Image; because the ratio already matches, nothing is stretched. If the horizon is tilted, straighten the photo in Rotate Image first, so the filled corners of the rotation are cropped away too.
What happens to format, quality and metadata
The pixels you keep are never resampled. How the result is saved depends on the source format.
PNG, BMP, TIFF, TGA and ICO
Saved in the same format without loss. Transparent areas stay transparent where the output format supports them.
JPG
Saved as JPG again at about the original quality setting, which ImageMagick estimates from the file. The re-save adds a little new compression loss.
WebP and AVIF
Saved in the same format at a fixed quality of 90 out of 100; WebP output is always lossy, even from a lossless original. Animated WebP stays animated, with every frame in full colour.
HEIC and HEIF
Saved as PNG, because the server can read these formats but not write them. The lossless PNG may be larger than the original; compare the actual sizes. Convert Image turns it into a JPG.
GIF
All frames and their timing are kept, along with each frame's colours, transparency and the loop setting.
EXIF and GPS data
Metadata such as the camera model and GPS position stays in a cropped JPG. To remove it, run the file through Compress Image with Strip metadata switched on.

Frequently asked questions
Can I lock the crop box to 16:9, 4:3 or 4:5?
Only 1:1: Square and Circle keep the box square while you resize it, and Center sets a centred square once. For other ratios, type W and H as shown above, then drag the box into place.
How do I get an exact size such as 1080 × 1080 px?
Crop to the matching ratio first, here a square, then scale the result in Resize Image. Cropping never scales, so a 3000 × 3000 px square stays 3000 × 3000 px.
Why is my circle crop a PNG, and why are the corners black or white?
JPG and BMP cannot store transparency, so their circle crops are saved as PNG with transparent corners. Viewers and upload forms without transparency support show those corners as a solid colour, often white or black.
Why is the cropped file larger than the original?
Usually the format changed or the file was re-encoded: HEIC and HEIF become lossless PNG, and circle crops of a JPG become PNG. A WebP originally saved at low quality can also grow, because the result uses quality 90. A JPG crop keeps fewer pixels, but its file size still depends on the image and re-encoding; compare the actual result.
Is my image uploaded to a server?
Yes. The crop runs on our servers with ImageMagick, or FFmpeg for GIFs, and the image is not sent to any AI service. Uploads and results are deleted automatically after the storage period listed under Formats and limits.
