纯好奇,很多平台对上传的图片都会进行压缩处理,不知道有没有人验证过,这个处理过程包不包含剔除图片的 EXIF 信息呢?

What happens to the Exif data for my photo?
When location services are enabled, and you attach a photo in the composer, Twitter refers to the Exif data of the photo to show suggested locations. 
In addition, Twitter uses Exif data for analytics purposes related to whether tweeted media was taken with the device camera. 
Twitter retains Exif data temporarily to process your photo. It is not available to those who view your photo on Twitter.
Twitter 是这么说的。
