About 图像标注器

Last updated: May 2026

OptiPix Image Annotator 是您一直缺少的那款截图标注工具 - 使用 Ctrl+V 粘贴截图,绘制箭头和矩形,添加文本标注,放置编号步骤标记,模糊电子邮件和密码等敏感信息,然后将结果复制回剪贴板,即可即时粘贴到 Slack、Jira 或电子邮件中。工具包括箭头、直线、矩形(描边或填充)、椭圆/圆形、自由手绘笔、文本标注、编号步骤标记、半透明高亮、模糊/像素化区域和裁剪。每种形状都支持颜色、粗细、填充不透明度和字体大小。选择任何标注即可移动、调整大小或删除它。通过 Ctrl+Z / Ctrl+Shift+Z 进行撤销/重做。“捕获屏幕”按钮使用 getDisplayMedia 来抓取屏幕、标签页或窗口。输出为 PNG 或 JPEG,或直接复制到剪贴板。所有内容都在本地渲染到画布上 - 您的截图绝不会被上传。

How It Works

标注存储为形状(箭头、矩形、文本等)的矢量列表,并在每一帧渲染到源图像上方的画布上。导出时,所有形状会被展平为单个 PNG/JPEG 位图,可以复制到剪贴板或下载。

Use Cases

  • 为工程团队创建带标注的错误报告
  • 为设计师添加反馈以标注设计模型
  • 使用编号截图构建分步教程
  • 在公开分享截图前模糊敏感个人信息
  • 在产品截图上添加箭头和文本以供文档使用

Frequently Asked Questions

我可以从剪贴板粘贴截图吗?
是的 - 按 Ctrl+V(或 Mac 上的 Cmd+V)直接粘贴截图。结合复制到剪贴板的输出,您可以获得最快的截图 → 标注 → 粘贴工作流程。
如何模糊敏感信息?
选择模糊工具,然后在该区域拖出一个矩形。选定的像素会被像素化/模糊处理,因此截图中的电子邮件、密码和个人数据将不再可读。
我可以添加编号步骤标记吗?
是的。数字工具会在您单击的任何位置放置一个带编号的圆圈(1、2、3…) - 非常适合分步教程和错误报告。
这个工具会上传我的截图吗?
不会。所有绘图都在本地画布上进行。屏幕捕获 API 完全在浏览器中运行,复制到剪贴板的操作永远不会接触到服务器。
我可以编辑绘制的标注吗?
是的 - 单击任何形状以选中它,然后拖动以移动,拖动控制柄以调整大小,或按 Delete 键将其删除。
