When you post on Moments, that doesn’t have to be the final version of the image or video. You can edit them even after they are already on WeChat. You can write on the image, draw, or crop it. Here’s how you can access the edit feature. 1. Open Moments in WeChat. 2. Press and hold the image you want to edit. 3. A small menu will appear. Select “Edit.” 4. Make the changes you want and select “Done.”
