上传图片即可自动裁剪出平滑圆角，解决直角图片在UI界面中显得生硬的痛点。该工具基于Canvas渲染技术，实时计算像素遮罩并输出透明背景PNG，适配各类网页与App设计场景。

上传的图片文件大小建议控制在10MB以内，过高分辨率可能导致浏览器渲染延迟。圆角半径超过图片宽高一半时将自动限制为圆形。所有处理均在浏览器本地完成，不会留存您的图片数据。

在Web前端开发中，CSS border-radius属性虽能实现圆角，但会因浏览器差异导致渲染不一致。使用本工具预生成带透明通道的圆角PNG，可彻底解决跨平台渲染兼容问题。建议为UI组件准备2x或3x尺寸素材，以适配Retina屏幕的高清显示需求。
