Instagram Post Generator

The Instagram Post Generator lets you build a realistic, clearly fictional Instagram feed post in seconds. Set the username, avatar, photo, caption, like count, and comments, then switch between light and dark mode. Everything runs in your browser and exports as a high-resolution PNG. It is perfect for marketers, designers, educators, and creators who need convincing mockups without touching a real account.

Instagram Post Generator features

Light and dark mode

Toggle between Instagram's light and dark themes so your mockup matches the device, deck, or campaign you are designing for.

Full post customization

Edit the username, avatar, verified badge, post image, caption, likes, timestamp, and comments to compose any scenario you need.

Use your own images

Upload your own photo and profile picture, then crop and zoom them to fit the frame exactly the way a real feed post would look.

High-resolution PNG export

Download a crisp, retina-quality PNG rendered at several times the on-screen resolution, ready for slides, mockups, and social graphics.

Private and client-side

All rendering happens in your browser with no login and no server upload, so your images and captions never leave your device.
