How do I create an Instagram mockup?
Upload your image, fill in the username, caption, likes and date, then pick the Instagram or Facebook look and the format (1:1, 4:5 or 1.91:1). The preview updates live; after that you download the mockup as a PNG – free with a watermark, or in HD without a watermark once you’ve entered your email. You can pair the result with the comment generator or an Instagram Reel mockup, and a cohesive campaign mockup often needs a DM & chat mockup too. You’ll find all the other helpers in our tools overview.
A mockup shows how a post can look – real reach only comes from the reactions to it. If you want to know how to actually capitalize on those interactions, read our guide to social media comment management or the overview of Instagram comments with AI. Once your posts are live, replient.ai automatically answers and moderates the comments in your brand voice, so every interaction turns into more.
