Instagram Mockup Generator

Preview posts and plan your feed with confidence.

Render your text and image as a realistic Instagram post so you can see it the way a follower will — before it is live. Useful for approvals, for pitch decks and for catching the awkward line break or the crop that eats the product.

How to use the Instagram Mockup Generator

  1. Type the post text and add a profile name and avatar.
  2. Upload the image you plan to use.
  3. Check how it reads at Instagram size, where only the first ~125 characters show before “more”.
  4. Download the mockup for the deck or the approval thread.

Frequently asked questions

Does this publish the post?

No. It is a preview image only. Publishing to Instagram needs a connected account — that is what OneClickPosts does.

Are my images uploaded anywhere?

No. The mockup is drawn in your browser on a canvas; the image never leaves your machine.

Can I use the mockup in a client deck?

Yes — that is the common use. It is a visual of your own content, so there is nothing to license.

Will the real post look exactly like this?

Close, not pixel-identical. Networks change their chrome constantly and render differently on each device. Trust it for layout and length, not for exact fonts.
