UlvixorImage Cropper
Upload an image and crop it by dragging your mouse directly over the preview to select the area you want to keep. The crop is generated with canvas in your browser and always downloaded as PNG. The file is never uploaded to any server.
How it works
- Select an image from your device using the file picker; a preview of the full image is shown.
- Click and drag over the preview to draw the rectangle that defines the area to crop.
- Adjust the selection by dragging again if the area isn't the one you want; the rectangle is drawn in real time.
- Press 'Crop' so the tool translates the selection into the image's actual coordinates and generates the crop.
- Review the crop preview and download it with one click; the file is always generated in PNG format.
Use cases
- Crop a photo to keep only the relevant part before sharing it.
- Extract a logo, icon, or specific element from a larger screenshot.

- Prepare an image cropped to the exact framing you need for a thumbnail or avatar.

Common mistakes
- Trying to crop without having dragged a large enough selection over the image.The 'Crop' button stays disabled until you draw a rectangle of a minimum size over the preview; if you don't see any effect, make sure you're dragging (click and hold while moving the mouse) over the image, not just clicking.
- Expecting the crop to be adjustable with exact numeric position and size values.This tool works only through visual selection by dragging over the image; it doesn't offer numeric fields to define exact crop coordinates.
- Assuming the crop keeps the original file format, for example JPG.The crop result is always generated as PNG, regardless of the original image's format. If you need the crop in another format, convert it afterward with the Image Converter.
