Instagram post generator

Make a fake Instagram post with a photo, caption, and likes, then download a PNG. Local-first. No signup.

What is an Instagram post generator?

An Instagram post generator (also searched as an Instagram post maker or fake Instagram post maker) lets you compose a feed-style post—photo, username, caption, and counts—and export it as a picture. Use this free local-first mockup for drafts and jokes. It does not publish to Instagram and it is not a screenshot from a real account.

Instagram post maker features

A local fake Instagram post mockup.

  • Feed layout

    Username, avatar, square photo, actions, likes, caption, and date.

  • Your photo

    Upload a post image and an avatar, or start from a color block and initials.

  • Light and dark

    Match a light or dark Instagram-style frame.

  • PNG export

    Download or copy the post. No watermark.

How to generate an Instagram post

From fields to a PNG.

  1. Fill the header

    Enter a username, optional location, and turn on the verified badge if you want it.

  2. Add the photo and caption

    Upload an image or keep the placeholder, then write the caption and counts.

  3. Export the picture

    Download a PNG or copy it for a joke, storyboard, or deck.

Tips for post mockups

Cleaner fake Instagram posts.
  • 01

    Use a square photo

    The frame crops to 1:1, which matches a classic feed post.

  • 02

    Keep the caption short

    One or two lines read more like a real feed screenshot.

  • 03

    Label it as a mockup

    If you publish the image, make it clear the post was composed, not taken from the app.

  • 04

    Skip the badge unless it fits

    A verified mark on a casual username looks less like a real account.

Great for

When an Instagram post maker helps.

  • Jokes and stories

    Illustrate a bit with a feed-style frame.

  • Content drafts

    Preview caption length and a photo crop before you post for real.

  • Decks

    Show sample social creative without logging into an account.
