Crop Image Online — Free, Round, or by Aspect Ratio
Crop image online in seconds, right in your browser. Drag a box over any part of your photo to keep just the area you want, lock it to a fixed aspect ratio, or switch to circle crop for a clean round profile picture.
Beyond a simple free-form crop, you can rotate and flip the image, zoom in for pixel-precise edges, turn on Rule of Thirds guides, and export the result as PNG, JPEG, or WebP with adjustable quality. It is built for social media posts, avatars, screenshots, and any image that needs trimming to a specific shape or ratio.
How to Crop an Image
Add your image
Click the upload area to pick a file, drag and drop an image onto it, or paste one from your clipboard with Ctrl+V (Cmd+V on Mac). PNG, JPG, WebP, GIF, and BMP are supported.
Choose a crop mode
Pick Free to crop any shape, Ratio to lock to a preset such as 1:1, 4:3, or 16:9 (or a custom ratio), or Circle for a round crop with a transparent background.
Adjust the crop area
Drag inside the box to move it and drag any of the 8 handles to resize. Use zoom or the mouse wheel for precision, and toggle Guides to align your shot with the Rule of Thirds. The output size in pixels updates as you go.
Rotate or flip (optional)
Rotate the image 90 degrees left or right, or flip it horizontally or vertically before cropping. Hit Reset any time to return to the original orientation.
Export the result
Choose PNG, JPEG, or WebP, set the quality if you like, then click Crop & Download to save the cropped image to your device.

Frequently Asked Questions
How do I crop an image online for free?
Upload your image, drag the crop box over the area you want to keep, then click Crop & Download. There is nothing to install or sign up for — open the page and start cropping.
Can I crop a photo into a circle?
Yes. Click the Circle button and the crop box becomes round with a 1:1 ratio. The result is exported as a PNG with a transparent background, which is perfect for avatars and profile pictures.
Can I set a custom aspect ratio?
Yes. Click Ratio, then enter your own width and height values in the custom ratio fields and apply them. You can also pick a preset such as 1:1, 4:3, 16:9, 9:16, or 4:5.
Does cropping reduce image quality?
Cropping keeps the original pixels inside the selected area, so the kept region is not scaled down or blurred. If you export as PNG the result is lossless; with JPEG or WebP you can use the quality slider to balance file size against detail.
What is the difference between cropping and resizing?
Cropping cuts away the parts of an image you do not want and keeps the rest at its original resolution. Resizing instead scales the whole image up or down to new dimensions. This tool crops — use it to trim or reshape, not to rescale the entire picture.
What image formats can I upload and export?
You can upload PNG, JPG, WebP, GIF, and BMP. For export you can choose PNG (lossless, with transparency), JPEG (smaller files for photos), or WebP (good compression at similar quality). Circle crops always export as transparent PNG.
What are the guide lines for?
The guides show the Rule of Thirds grid, a classic composition technique. Placing key elements along these lines or at their intersections often makes a crop look more balanced and engaging. Toggle Guides on or off any time.
Are my images uploaded to a server?
No. All processing happens entirely in your browser. Your images never leave your device, so cropping is completely private.
