Most social media platforms do not accept HTML5 designs, so when you export your design for social media you should export it as a static JPG image or video (MP4).
To export your social design as an MP4 video, check out our guide on how to Export to Video MP4.
To export static JPG images for a social media platform, open the Export panel on the right-hand side of the editor and open the Social tab. Under the Export As options, ensure that Static JPG is selected. Next, select the sizes you'd like to export, and then click 'Export Design (.ZIP)'.
If your design has an animation sequence, Flexitive will export a static image from the last frame of the animation sequence.
