What Is This Tool?
The Instagram Post Generator is a browser-based mockup tool that recreates the Instagram feed post card — the gradient-ringed circular avatar, an @username with an optional blue verified checkmark, a photo placeholder, the heart/comment/share/bookmark action row, a like count, a caption with hashtags, and the "View all N comments" line — so you can type your own content and export it as a shareable image.
For entertainment and design use only: this tool is built for jokes, memes, presentation slides, UI/UX prototypes and social media content. It must never be used to fabricate fraudulent evidence, harass or defame someone, or impersonate a real person's actual post — doing so can be illegal depending on your jurisdiction and is strictly against the intended use of this tool.
Nothing you type ever leaves your device — the whole post is rendered with the HTML Canvas API directly in your browser, and the PNG is generated and downloaded locally. There is no server upload, no account and no tracking of your content.
Why Use It?
- You're writing a meme where the joke is the caption and engagement numbers on a ridiculous fake post, and you need it to look like an actual feed screenshot rather than plain text over a photo.
- You're pitching an influencer marketing campaign to a client and want to show what a sponsored post could realistically look like — caption tone, hashtag style, and a believable engagement count — before any real content exists.
- You're a UX designer testing how a caption of a certain length wraps, or how a five-digit versus six-digit like count affects the feed card's layout, and need quick disposable mockups rather than screenshotting a real account.
- You're building a course, tutorial, or case study slide that walks through "what a good Instagram caption looks like" and need a realistic example image rather than a block of text pretending to be a screenshot.
- You want to preview how your actual caption and hashtags will look once posted — wrapped, colored, and laid out exactly like Instagram's real feed card — before you commit to posting it for real.
- 100% local rendering — your caption and numbers never touch a server.
How to Use
- Set the username (@handle), avatar color or upload a photo, and toggle the verified badge.
- Write the caption and hashtags, and choose whether to show a photo placeholder.
- Set the like count and comment count shown under the post.
- Watch the feed-card preview update live, then click "Download PNG" to save the image.
Example
Input
Username: "@alex.rivera" · Verified: on · Caption: "Golden hour on the coast never disappoints ✨" · Hashtags: "#travel #sunset #ocean" · Likes: "4,281" · Comments: "63"Output
A 480×576 PNG image showing an Instagram feed post: gradient-ringed avatar and username with a blue checkmark, a photo placeholder, the heart/comment/share/bookmark row, "4,281 likes", the caption with hashtags in blue, and "View all 63 comments".The image is generated instantly in the live preview canvas and downloads with a single click — no waiting, no upload.
What you can customize
- Username (@handle), avatar color or uploaded photo, and a toggleable blue verified badge.
- Caption text with hashtags, rendered in Instagram's link-blue color.
- Like count and comment count, shown exactly as real Instagram posts display them.
- An optional photo placeholder area, matching Instagram's square feed-image proportions.
Responsible use
This generator exists to make it easy to create clearly fictional Instagram post images for humor, storytelling and design work. It is not a tool for fabricating evidence, staging harassment, or misleading anyone into thinking a fake post is real. If you plan to share an image made with this tool, consider adding context (like "fake" or "mockup") so viewers understand it is not an actual Instagram post, especially when the subject could be mistaken for a real person or real events.
Writing a caption that reads as real
A mockup's caption and numbers do most of the work in making it feel authentic — the layout is already accurate, so a caption that reads like ad copy rather than a real post is usually the giveaway that something was staged.
Real Instagram captions tend to open with a short, punchy first line (since that's what shows before "...more" truncates it), then trail into a few more sentences or a joke, followed by a cluster of hashtags at the end rather than scattered mid-sentence. Engagement numbers should scale with the account size you're implying — a caption written like a small personal account paired with a six-figure like count reads as obviously fake, while a believable ratio (dozens to low hundreds of likes for a personal account, thousands-plus for something implying a larger following) does more for realism than any visual detail in the mockup itself.
Frequently Asked Questions
Is it legal or ethical to use this tool?
The tool itself is legal to use for entertainment, mockups, presentations and design work. What is not legal or ethical is using the generated image to deceive someone — for example presenting it as a real post to commit fraud, harass or defame a person, or impersonate someone's actual content. Depending on where you live, that kind of misuse can constitute fraud, defamation or harassment. Please only use this for clearly fictional or illustrative purposes.
Does the tool upload my caption or numbers anywhere?
No. Everything you enter stays in your browser's memory and is drawn directly onto a canvas element using JavaScript. The PNG file is generated and downloaded on your device — nothing is ever sent to any server.
Can I turn off the verified badge?
Yes — the blue checkmark next to the username is a simple checkbox toggle, so you can generate both verified and non-verified account mockups.
Can I upload a real photo as the avatar or feed image?
You can upload a real photo for the circular avatar. The feed photo itself is a colored placeholder rectangle by design, to keep the tool simple and avoid any temptation to pass off someone else's real photo as your own post.
What image size does it export?
The preview and exported PNG use a feed-card aspect ratio that looks natural when shared on social media or embedded in a presentation.
Should I use this or one of the other Instagram mockup generators?
If you're mocking up a permanent feed post with a caption, hashtags and a like/comment count, use this Post generator. If you need a full-screen vertical Story instead, use the Instagram Story Generator; if you only need the comment thread under a post, use the Instagram Comment Generator; if you need a whole profile page with bio and post grid, use the Instagram Profile Generator.
Does the tool count hashtags or characters for me to stay within Instagram's limits?
No automatic counter is built in, but Instagram allows up to 30 hashtags per post and roughly 2,200 characters in a caption — well beyond what looks good in a mockup anyway, since a caption that long gets truncated with "...more" in the real feed. Keep your caption to a few lines and your hashtags to a handful if you want the mockup to resemble how a real post typically displays before a viewer taps to expand it.
Can I make the like count and comment count show "0" or hide them entirely?
You can set the like and comment counts to "0" directly in the input fields, which is useful for mocking up a fresh or low-engagement post; there isn't a separate toggle to hide the numbers completely, since that row is part of Instagram's standard feed layout.
Will the hashtags actually render in Instagram's blue link color?
Yes — the caption text is rendered with hashtags automatically colored in Instagram's characteristic link-blue, matching how real hashtags and @mentions display in the app, so the mockup reads as visually authentic rather than plain black text with hash symbols.
Can I create multiple post mockups and compare them side by side?
The tool generates one post at a time, but nothing stops you from downloading several PNGs with different captions, like counts, or verified-badge settings and laying them out side by side afterward — useful for A/B-testing caption ideas or comparing verified versus non-verified presentation before you decide which version to actually use.
