Instagram Post Mockup Generator

Mockups show how a post will look in the feed before it goes live. Marketers use them in ad creatives, agencies use them to present content to clients, and creators use them to check that an image and caption work together on a phone screen.

Square (1:1), portrait (4:5) and landscape (1.91:1), the three feed ratios Instagram supports for photos. Upload any image and it is cropped to the ratio you pick. Use the crop position slider to choose which part stays in frame. For the best quality in the real app, upload 1080 x 1080, 1080 x 1350 or 1080 x 566 pixels.

In the feed Instagram shows about two lines, usually around 125 characters, before cutting the caption with “… more”. The exact point depends on the screen width and the length of your username. The mockup measures the text the same way, so you can see where your hook gets cut off.

Please don't. Use your own account or neutral sample names. Mockups are meant for ads, presentations and planning. Using them to impersonate a person or brand, fake an endorsement or invent engagement numbers can mislead people and breaks Instagram's rules.

No. Everything is drawn in your browser on a canvas. Your images never leave your device, and nothing is stored once you close the page.

The mockup is 390 pixels wide, the width of a modern phone screen, and exports at 2x (780 pixels) or 3x (1,170 pixels) so it stays sharp in slides and ad creatives.
