Apple has introduced a new image format in iOS 11 called HEIF (.heic file extension). I know you can export images as JPG from iOS devices, but I want to upload the HEIC-files to my server and convert them there to JPEG files that can be shown on all other devices.
苹果在iOS 11中引入了一种新的图像格式HEIF (HEIF)。heic文件扩展名)。我知道你可以从iOS设备上以JPG格式导出图像，但是我想把heic文件上传到我的服务器上，并将它们转换为JPEG文件，这些文件可以在所有其他设备上显示。
Can anyone recommend a good and efficient way to achieve this?
有人能推荐一种有效的方法来实现这个目标吗?

答:
Since this question has been closed, I will edit in my answer here for the rest of you. We now use this library for converting HEIC to JPEG: https://github.com/monostream/tifig
既然这个问题已经结束了，我将在这里编辑我的答案。我们现在使用这个库将HEIC转换为JPEG: https://github.com/monostream/tifig。
Also ImageMagick now support converting HEIC to JPEG thanks to a fork from @toshic
另外，ImageMagick现在支持将HEIC转换为JPEG，这要感谢@toshic提供的fork
Thank you to @monostream and @toshic for your great contributions!
感谢@monostream和@toshic为您所做的巨大贡献!

It's complicated because iOS 11 is actually storing tiles of HEVC encoded images in a HEIF container, but there's a demo using the nokia lib to extract them all, ffmpeg to decode them and then stitching them into a single jpeg with imagemagick in the heiftest repo linked from corrupted HEIC tile when converting to JPEG

We also have a working one you can use by cloning https://github.com/pushd/heif and then:
我们还有一个可用的，您可以通过克隆https://github.com/pushd/heif来使用，然后:

CloudConvert supports to convert these HEIC files to JPG: https://cloudconvert.com/heic-to-jpg. They also have an API with PHP/node.js/Python SDKs.

There is no such library available right now for image conversion on a server for HEIF to JPEG, ImageMagick doesn't have support for that till now.
现在还没有这样的库可以在服务器上对HEIF到JPEG进行图像转换，ImageMagick到现在还没有支持。
The only way you can do this by exporting your images from your device, that should produce a JPEG image.
要做到这一点，唯一的方法是从设备中导出图像，这会生成一个JPEG图像。
Nokia has a HEIF reader javascript implementation which you can have a look at: Nokiatech heif
诺基亚有HEIF阅读器javascript实现，你可以看看:Nokiatech HEIF
Alternate: You can try this website if this works.
