Why 100MB, not the official maximum

Xiaohongshu’s published caps are generous. Uploading a multi-gigabyte 4K file on a phone still fails or gets crushed on the way in.

A 100MB 1080p H.264 file uploads quickly and gives the app less reason to hammer the bitrate. Product shots and captions stay cleaner.

Vertical 3:4 and 9:16 files work. We do not crop — compress whatever you have; crop in your editor first if you need a different frame.
