What the tool does, how to run it, and what to expect from the result.

How to make a mock Instagram post image

Set the username, the like count, and the caption, and optionally upload a photo. The canvas composes a post at 540 points wide, rendered at 2x for a 1,080 pixel PNG, with a square image area, a header with an initial avatar, and a footer with the like count and caption.

It is a mockup for design and presentation work. There are no action icons, no comment count, and no timestamp, which is what keeps it a clear illustration of a post rather than an imitation of one.

  • Type the username, which also sets the letter shown in the avatar circle.
  • Type a like count, remembering that the field is free text and is not validated.
  • Write the caption, which wraps automatically and grows the footer.
  • Upload a square image if you have one; a non-square photo is cover-cropped to the 1:1 frame.
  • Click Download PNG to save the 1,080 pixel wide mockup.

About this Instagram post generator

Set a username, like count, and caption, and optionally upload an image (a gradient is used if you skip it). The post is drawn on a canvas so you can download a clean image. It is a mockup for design and fun, not for impersonation.

Tips

Getting a better result out of Instagram Post Generator

Specific settings and thresholds, not general advice.

  • The canvas is 540 points wide rendered at 2x, so the exported PNG is 1,080 pixels across, which is exactly the width Instagram renders a feed image at. The image area is a 540 by 540 square, matching the 1:1 crop.
  • Your uploaded photo is fitted with a cover crop, scaled to fill the square and centred, so anything outside the square is cut off. That is the same thing Instagram does, and it is why a wide landscape photo loses its edges here exactly as it would in the app.
  • With no image uploaded, the square is filled with the Instagram gradient (yellow through magenta to blue), which makes it obvious at a glance that this is a placeholder rather than a real post.
  • The likes field is free text, not a number, so it renders whatever you type. That is a convenience for mockups and it is also a warning: an invented like count in a screenshot presented as real is a fabricated metric, and using it to sell a service or a sponsorship is fraud.
  • The avatar is generated from the first letter of the username on a pink circle. There is no avatar upload, which is one of several reasons the render reads as a mockup rather than as a capture of a real profile.
Limits

What Instagram Post Generator does not do

The honest boundary, so you do not lose time finding it yourself.

  • No action icons (heart, comment, share, save), no comment count, no timestamp, and no verified badge.
  • No avatar image upload. The profile circle is a coloured initial.
  • Square 1:1 image only. There is no portrait 4:5 or landscape crop, and no carousel.
  • The likes field is unvalidated free text, so nothing stops it from being nonsense or from being misleading.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is the Instagram Post Generator free?

Yes. It is completely free, with no sign-up, no watermark, and no usage limits.

Is my image uploaded?

No. If you add an image it is processed locally in your browser with a canvas, so it never leaves your device.

Can I download the post?

Yes. The mockup is rendered on a canvas and downloads as a PNG.

Why is my photo cropped?

Because the image area is a 540 by 540 square and your photo is fitted to cover it, centred, with the overflow cut off. Crop the image to a square first if you want to control exactly what is kept.

What size is the exported image?

1,080 pixels wide, from a 540 point canvas rendered at 2x. The height depends on how many lines your caption wraps to, since the footer grows to fit.

Can I add a verified badge or comment count?

No. The mockup renders a header with a username and initial avatar, the image, a like count, and a caption. Nothing else is drawn.

Is it acceptable to invent the like count?

For a design mockup, a slide, or a tutorial, yes, because nobody is being asked to believe it. Presenting an invented like count as real engagement, to a client, an advertiser, or a platform, is misrepresentation, and no design need requires it.

Does my photo get uploaded?

No. It is decoded into a canvas in your browser and composited there. The PNG is generated in your tab and never sent anywhere.
