Issue:
[Feature Request]: [batch processing] file compression ratio is not controlled,can you add control to it?
### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

when we are in the img2img  batch processing,the output file format defaults to highly compressed jpg,
under the resolution of 896x1200,it's only 45k,this is great,
but a lot of times,we don't want to lose image quality to save storage space,
although i have set [save jpeg picture quality] to 100% in [settings] [image save settings],
but it didn't work,i can't control it,
is there any way i can improve the quality of the picture myself?

### Proposed workflow

1. [settings] --[image save settings],
2. [save jpeg picture quality] to 100%
3. [img2img] --  [batch processing] the quality of the output picture will be controlled,
