Every network displays images and videos in its own frame. iZop Composer and Copilot previews mirror each platform's feed layout: caption placement, action buttons, and the aspect ratio closest to your uploaded file. Use this guide when you export creative from design tools so posts look sharp without unexpected cropping.
Composer checks every selected platform when you upload a photo or carousel slide. If a file is too large or the wrong format for any network in your post, upload is blocked until you pick a compatible file or let iZop convert it.
