Crop Image Online Free — Custom Aspect Ratio, No Upload

Cropping a picture to focus on the subject or create a circular profile avatar should be quick and confidential. With Pexlii, you do not need to install photo editing software or send personal pictures to external web servers. When you load a photo, our tool renders it onto an interactive HTML5 workspace in your browser memory. You can freely adjust the crop boundary, lock standard aspect ratios such as 1:1 square, 16:9 widescreen, or 4:3 standard, or toggle the circular avatar mask for Discord, Slack, and social media profile pictures. When you hit crop, the tool reads the exact pixel coordinates of your selected bounding box and extracts that sub-region from the source image buffer onto a clean canvas. If you used circular crop mode, the outer pixels are rendered transparent as a crisp PNG file. Everything finishes in milliseconds on your local hardware with zero data leaving your device.
