About Xiaohongshu Image Compressor
On Xiaohongshu (RED), the vertical 3:4 frame at 1080×1440 px takes up the most screen space in the feed and tends to earn longer dwell time than square or landscape images. The app also re-compresses whatever you upload, so starting from a clean, right-sized file means the version readers actually see stays sharper. This tool helps you check your image against that recommended size and compress it so it uploads quickly without visible quality loss.
Make covers count
The first image is your cover and does most of the work in the feed — keep its key subject and any text well inside the frame so nothing gets cropped by the app's thumbnail. Compress after you've finalized the crop, not before.
