How to make an Instagram post mockup
No account, no sign-up, completely free. The mockup renders live and the PNG is generated in your browser, so neither your caption nor your photo is ever uploaded to a server.
Upload the photo
Start here. Instagram is image-first, so the photo carries the card and everything else arranges itself around it.
Write the caption
Set the handle, an optional location, and the caption. Keep it short and lowercase, the way real captions run.
Download the PNG
Set the likes and comments, add a couple of visible replies, then export a crisp 2x PNG for a slide, a comp, or a meme.
The Details
What makes a card read as Instagram
Facebook and Instagram are both feeds owned by the same company, and mockup tools routinely draw one and relabel it. Three details separate them, and all three are easy to get wrong.
photo first + caption below + no share count
The image comes before the words, the caption sits under the action icons prefixed with the handle, and there is no public share count anywhere on the card, only likes and comments.
The comment styling is the other giveaway. Facebook wraps each comment in a rounded gray pill. Instagram runs them as plain text under the caption, with the handle in bold and nothing behind it. If you have ever looked at a mockup and felt that it was Instagram-ish without being able to say why it was off, this is usually the reason.
After that it is proportion. Comments tend to land at a small fraction of the likes, and captions run short. A card with eight thousand likes, three comments, and a four-sentence marketing paragraph is internally inconsistent in three directions at once, no matter how accurate the chrome around it is.
Two things worth saying plainly. Believable styling is for design work, never a reason to present a mockup as a real post, and on this platform that particularly means not inventing brand deals or endorsements. And because the card is built around a photograph, use images you actually have the rights to.
Settings
Every setting, and when to use it
Seven controls shape the look of the export. This is what each one does and the job it is best suited to.
| Setting | What it does | Best for |
|---|---|---|
| Photo | The image the whole card is built around, shown at full width | Not optional in practice. Instagram is image-first, so this carries the mockup Most used |
| Handle | The username at the top, with a gradient ring around the avatar | Lowercase with a dot or underscore. Never a formatted first and last name Most used |
| Location | A small line under the handle | A detail most mockups skip. Adds a lot of realism for one short field Situational |
| Caption | Text under the action row, prefixed with the handle in bold | Instagram puts the caption below the photo, never above it Most used |
| Likes and comments | The like count and the "View all N comments" line | Instagram shows no share count publicly, which is why there is no field for one Most used |
| Visible comments | Up to six comments as plain text, each with a handle and a like count | Plain text, not gray bubbles. That is the clearest difference from a Facebook post Situational |
| Dark theme | True-black card rather than a white one | What a large share of Instagram users actually see, and better for reels Most used |
Themes follow the common light and dark Instagram palettes as of 2026. This tool is a generic design mockup and is not affiliated with, or endorsed by, Instagram or Meta.
Use It Right
Good uses, and the two to never touch
A post mockup is a design asset. These are the everyday jobs it is built for, and the uses that turn it into something else entirely.
| Scenario | What it is | Verdict |
|---|---|---|
| Client and portfolio comps | Showing how a photo or a campaign will look in a real feed before anything ships | Good use |
| Pitch decks and case studies | Illustrating a social strategy with example posts that do not exist yet | Good use |
| Memes and skits | Clearly humorous posts from invented accounts | Good use |
| Product and app mockups | Filler feed content in a UI comp or a design system example | Good use |
| Faking an endorsement or brand deal | Inventing a post from a real brand or creator to imply a partnership that never happened | Never |
| Impersonation or faked evidence | Presenting a mockup as a genuine post from a real account | Never |
Avoid These
What gives a mockup away, and the line never to cross
Four of these are craft. The first two are not negotiable. Read them before you export anything that will leave your own screen.
Passing it off as a real post
The one rule that matters more than every design tip here. A mockup is not a record of anything. Using one to claim a partnership, win an argument, or mislead a client or a platform is fraud, not design.
Never present it as realUsing a photo you do not own
This one is specific to the image-first platforms. The mockup card is generic, but the photo inside it is somebody’s work. Use your own images, or licensed ones, especially if the export leaves your machine.
Own the photoA display name instead of a handle
Instagram leads with the username. "Studio Oak" in the header reads as Facebook. Something like studio.oak is what a real post shows.
Handles, not full namesInventing a share count
Instagram does not display shares publicly, only likes and comments. A mockup showing a share count is instantly wrong to anyone who uses the app, which is why this tool has no field for one.
No public share countComments in gray bubbles
That is Facebook’s pattern, not Instagram’s. Instagram runs comments as plain text under the caption. Mockups made in a generic post tool almost always get this wrong.
Plain text commentsA caption written like an ad
Captions on Instagram run short, lowercase, and often a little oblique. A polished marketing paragraph is the fastest way to make the whole card read as staged.
Short and lowercaseBest Practices
8 tips for a post mockup that lands
All CommonNinja widgets mentioned below are free to start. Apply these while you build the card and after you place the image.
01
Start with the photo
Everything else is furniture around the image. Pick or shoot the photo first, then write a caption that suits it, rather than designing the card and dropping an image in at the end.
02
Use a square image
The card renders the photo at full feed width. A square or near-square crop sits in the layout the way a real post does, where a very tall or very wide image will not.
03
Default to dark mode
A large share of Instagram users run the app dark, so a black card often reads as more authentic than a white one, and it makes most photos look better too.
04
Add the location line
One short place name under the handle is on almost every real post and missing from almost every mockup. It is the cheapest realism available here.
05
Keep the like-to-comment ratio sane
Comments usually land somewhere around a fortieth of the likes, give or take a lot. Eight thousand likes with three comments, or with six thousand, both read as invented.
06
Write the caption in lowercase
Not a rule, but a very strong convention, especially for design, art, and creator accounts. It is a small signal that does a lot of work.
07
Put your real grid on your own site
A mockup is a graphic. An embedded feed is your actual Instagram, refreshing itself on a page you own, so the audience you earned lands somewhere you control.

Fit the grid into a tight layout
If a full feed is too much for the space, a slider shows the same work in one row and keeps the rest of the page intact.
