If possible, try to compress images and videos on the front end before uploading. This can reduce the capacity of images and videos, speed up loading, and reduce storage capacity:
WeChat Mini Program pictures can be used [https://developers.weixin.qq.com/miniprogram/dev/api/media/image/wx.compressImage.html](https://developers.weixin.qq.com/miniprogram/dev/api/media/image/wx.compressImage.html)
WeChat Mini Program videos are available
[https://developers.weixin.qq.com/miniprogram/dev/api/media/video/wx.compressVideo.html](https://developers.weixin.qq.com/miniprogram/dev/api/media/video/wx.compressVideo.html)
uni-app corresponds to `uni.compressImage` and `uni.compressVideo`
H5 can use corresponding npm components, and other methods such as native apps can use corresponding solutions.
