About this fake instagram post generator
With the fake Instagram post generator you can turn any photo you own into an Instagram-style square post. Add a username and avatar, a location line, a caption with hashtags and a like count, then switch between light and dark feeds. The preview shows the familiar heart, comment and share icons.
Show off your 'gourmet' sandwich, your dog's graduation or a rock named Dwayne. Your photo is processed in your browser and never uploaded, and the exported image always includes a small Prank watermark. Change the caption or swap the photo as often as you like; your draft autosaves locally, so a refresh won't lose your best hashtags.
How to make a fake Instagram Post (for fun)
- Pick a prank idea. Start from one of 4 ready-made ideas, or keep the default instagram post.
- Edit the details. Change names, avatar, messages, times, counts and theme in the Content panel — the preview updates as you type.
- Check the preview. On a phone, switch to the Preview tab; the mockup scales to fit your screen.
- Download or share. Save a PNG or JPG at 2x or 3x, copy it, or share it straight from your phone. Then reveal the joke!

Keep it a joke. Mockly makes parody images for fun. Never use a mockup to deceive, defame, harass or defraud anyone, and don't pose as a real person's or brand's official account. Every export carries a small “Prank · altftool.com” watermark. Not affiliated with Instagram or any app shown.

Is it legal to make a fake Instagram screenshot?
Making a parody image for a joke is generally fine. Using one to deceive, defame, harass, impersonate or defraud someone can be illegal and breaks every platform's rules — so don't.
