Fake Instagram post generator
A pixel-close Instagram feed post mockup: your username, image, caption, and numbers, exported as a clean PNG. For decks, client approvals, and courses. Nothing gets posted.
The honest-use line
- Client approvals and decks: show the post as it will look in the feed before anything is published. The everyday professional use.
- Courses and tutorials: teach caption structure or feed aesthetics with examples you control instead of borrowing someone's real post.
- Fabricating posts from real people or brands and presenting them as authentic: not fine, and impersonation is against Instagram's rules regardless of the tool used.
- Everything is client-side: your images become data URLs in browser memory and are gone when you close the tab.
Frequently asked questions
How do I make a fake Instagram post?
Set the username, upload the post image and an avatar if you want one, write the caption, and adjust likes, comments, and the time label. Then download the card as a PNG or copy it to your clipboard. Everything renders in your browser; nothing is posted to Instagram and nothing is uploaded to us.
Is it legal to make a fake Instagram post?
Creating a mockup image is normal creative work: ads, pitch decks, tutorials, and social media courses are full of them. The line is deception: presenting a fabricated post as something a real person or brand actually published can be defamation, and impersonating accounts violates Instagram's terms. Mock up, don't mislead.
Does this connect to Instagram at all?
No. There is no login, no API call, and no draft created anywhere. The tool draws a picture of a post that does not exist, and the images you upload stay in your browser's memory as data URLs.
What image size works best?
Square (1080 x 1080) or portrait (1080 x 1350) sources look most like a real feed post. The mockup renders your image at feed proportions, so a very wide screenshot will be center-cropped the way Instagram itself would crop it.
Why mock up an Instagram post instead of screenshotting one?
Because the post is not live yet: planned launches, client approval flows, course slides, and A/B caption tests all need the visual before publishing. This gives you the pixel-faithful preview without touching a real account.
From mockup to published, same picture
posthell schedules real Instagram posts (it even warns you when media is missing or off-aspect), tailors captions per network, and shows what each post did. The mockup is the pitch; the calendar is the delivery.
