免费图片旋转工具
图片方向不对时,在浏览器里本地旋转或翻转后再上传或发布。
先在本地修正图片方向,再上传或发布。
关于这个工具:免费图片旋转工具
Rotate and flip local images in the browser when orientation is wrong before upload or publishing. 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
- 手机照片方向错了,优先用 90 度旋转修正。
- 只有主体或文字镜像时才需要翻转。
旋转与镜像:修正图片朝向
旋转看着是小事,直到手机拍的照片横着送来、或者扫描件左右反了。请直接旋转像素来修正朝向,而不是依赖下一个工具可能忽略的元数据。
正确修朝向
- 1
旋转像素,而不只改标记
EXIF 朝向只是元数据,很多流程会把它剥掉。烘焙进像素的旋转不会丢。
- 2
能按 90 度转就按 90 度转
直角旋转是像素精确重排,不掉画质;任意角度必须整图重采样。
- 3
含文字的图要再确认一次
镜像的图看着挺正常,直到你发现文字反了——扫描件最常见的破绽。
旋转常见问题
- 为什么同一张照片在一个软件里是横的、另一个里是正的?
- 一个读 EXIF 朝向标记,另一个忽略它。直接旋转像素就能终止这种分歧。
- 旋转会降低画质吗?
- 按 90 度转不会;任意角度会重采样,略微变软。
- 是在本地吗?
- 是,而且免费。处理在浏览器本地进行,文件不会上传,也不消耗积分。
