免费图片元数据清理工具
通过浏览器 画布 重绘生成干净副本,减少常见嵌入元数据再分享。
先在本地生成更干净的副本,再分享敏感图片。
关于这个工具:免费图片元数据清理工具
Redraw images through browser canvas to create clean copies without common embedded metadata. 无需上传——全部处理都在你的浏览器本地完成,兼顾隐私与速度。
常见用法
- 画布 导出会生成新图片,通常不会保留大多数嵌入元数据。
- 如果后面还要相机、色彩或作者信息,记得保留原图。
分享之前先清掉图片元数据
一张照片带的远不止画面:相机型号、拍摄时间,往往还有拍摄地点的 GPS 坐标。发布之前把这些清掉,是隐私动作,不是技术洁癖。
清什么、什么时候清
- 1
先清位置
GPS 坐标是最敏感的字段,也是公开发图时最容易被忽略的那一个。
- 2
时间也要考虑
拍摄时间会暴露「某个地方那时没人」,而这恰恰是有些照片不该透露的信息。
- 3
留一份带元数据的副本
要发布的是清过的副本;原图存档,别把以后可能需要的记录也一起丢掉。
清除元数据常见问题
- 清除元数据会改变画面吗?
- 不会。唯一的例外是朝向,所以清完之后确认一下图没有被转歪。
- 原文件会被改吗?
- 不会,工具会另写一个新文件,你的源文件保留原有元数据。
- 是在本地完成吗?
- 是。这个操作在你的浏览器里完成,文件不会上传到任何服务器。
