Picture compression function

[KormiMeiko]

Summary

I hope you can add a compressed file size function to the image upload

[Johann150]

I think if you want to compress the file, you should do it before uploading. If Misskey has to compress the file, it could be complicated.

I think it would be useful, since continuously uploading large images can stress drive space.

Maybe there should be an option to save only the webpublic and not the original.

I agree with this view very much!
There may be another way:

Maybe so, but I just want to have this function to make it as convenient as possible for community users~

There is a drive size limit. So users should pay attention to how much space they have left. And then they hopefully notice that it may not be much and know to upload smaller images. It is easy to do using e.g. Paint and resizing the image to a smaller size.

If it is easy for community users, then it is probably hard for developers.
Also it might be hard on the servers CPU, unless it is done with JavaScript. But using JS for this sounds like a bad idea to me.

Even now, Misskey servers always compresses the file when the image is uploaded.
(As for remote images, it depends on the instance settings.)

クライアントで変換してあげるといい感じになる。
実装上はcanvas展開してブラウザでjpg変換しているので、変換もアップロードも速くなる。
