Hello, upload to China Photography and Popular Photography. How much should the photos be compressed without changing the original pixels? ...

No compression is required. Generally, SLR is in RAW format. When a manuscript is submitted, it is converted into JPG format for copyright protection.

If you shoot in JPG format, you should compress it before submitting it, which is also for copyright protection.

If it's taken in medium format, you'd better compress it, otherwise it's too big.
