About Xiaohongshu Image Compressor / 关于本工具
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.
在小红书，竖向 3:4、1080×1440 像素的画幅在信息流里占屏最大，比方图或横图更容易获得更长的停留。App 还会对你上传的图再压一次，所以从一张干净、尺寸合适的文件出发，能让读者最终看到的版本更清晰。本工具帮你对照该推荐尺寸检查图片，并压缩到能快速上传、又看不出损失的程度。
Make covers count / 封面要讲究
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.
第一张是封面，在信息流里承担最主要的曝光——把主体和文字都留在画面安全区内，避免被 App 缩略图裁掉。务必先定好裁剪再压缩，不要颠倒顺序。
