About Instagram Post Generator

The Instagram Post Generator builds a pixel-accurate visual mockup of an Instagram post inside your browser. You fill in a username, upload a profile picture and a post image, write a caption up to 2,200 characters, set like and comment counts, and the tool assembles the full Instagram card in real time — header, image, action bar, like count, caption, and timestamp — exactly as it appears in the app. You can switch between square (1:1), portrait (4:5), and landscape (16:9) aspect ratios to match real Instagram post dimensions.

Unlike the Instagram Line Break tool (which fixes caption spacing) or the Instagram Font Generator (which converts text to Unicode styles), this tool is for building a complete post image. It is aimed at UX designers mocking up social media screens, marketers producing before-and-after concept art, educators showing students what a finished post looks like, and content creators who want to preview their caption alongside the actual photo before they publish. A "Fill Demo Data" button lets you populate every field instantly for a quick demonstration.

Everything runs entirely in your browser. Your photos, captions, and profile pictures are never sent to any server — they are loaded via the FileReader API and kept in local memory for the duration of your session. The export button uses html2canvas to render the visible preview at 2x resolution and download it directly as a PNG file. There is no account required, no watermark added, and no file size limit.

Key Features

check_circle

Three post aspect ratios

Choose Square (1:1 / 1080×1080 px), Portrait (4:5 / 1080×1350 px), or Landscape (16:9 / 1080×608 px) to match the exact dimensions Instagram uses for each format.

check_circle

Full engagement metrics

Set any like count, comment count, and share count. Numbers above 1,000 are automatically formatted as 1.2K, and above 1 million as 1.2M, matching Instagram's real display.

check_circle

Dark and light theme toggle

Switch between Instagram's dark and light colour schemes in one click. The preview — including the background, borders, text colours, and icon strokes — updates instantly to match.

check_circle

UI detail toggles

Turn individual Instagram UI elements on or off: verification badge, story ring gradient, Follow button, "liked by viewer" filled heart, tagged-users indicator, and comment count row.

check_circle

2x resolution PNG export

The export button captures the live preview using html2canvas at double pixel density. The resulting PNG is crisp enough for slide decks, portfolios, and client presentations.

check_circle

Mobile and desktop preview widths

Toggle between a 375 px mobile-width card and a 468 px desktop-width card so you can check how the layout reads at both breakpoints before exporting.

Common Use Cases

  • arrow_circle_right

    Social media pitch decks

    Designers and agencies drop the exported PNG into client presentations to show exactly how a campaign post will look inside the Instagram app, without needing a live account or draft post.

  • arrow_circle_right

    Before-you-publish caption review

    Content creators upload their photo, paste the full caption including hashtags, and check how the text wraps and truncates at the "more" threshold before going live.

  • arrow_circle_right

    UX and app design mockups

    Product designers embedding social feeds in app prototypes use the exported card as a realistic Instagram post asset instead of a hand-drawn placeholder.

  • arrow_circle_right

    Educational demos and tutorials

    Teachers and workshop facilitators generate a sample post to walk students through Instagram UI terminology — post size, engagement metrics, verification badges — using a controlled, offline example.

  • arrow_circle_right

    A/B testing caption and image concepts

    Marketers generate two versions of the same post with different captions or cropping ratios side by side to compare visual weight and readability before scheduling.

Frequently Asked Questions

What is an Instagram Post Generator? expand_more
An Instagram Post Generator is a tool that builds a realistic visual mockup of an Instagram post — complete with profile header, post image, action icons, like count, caption, and timestamp — so you can preview or export the full card without posting anything to the platform.
Is my data safe and private? expand_more
Yes, completely. All processing happens locally in your browser using JavaScript. No images or data are uploaded to any server. Your photos, captions, and profile pictures stay entirely on your device until the session ends.
What image formats can I upload? expand_more
You can upload any standard image format supported by your browser, including JPG, PNG, GIF, WebP, and SVG. Images are loaded through the FileReader API and displayed using native browser rendering.
How is this different from the Instagram Line Break tool? expand_more
The Instagram Line Break tool is a text-only utility: you paste a caption and it adds invisible spacing characters so the line breaks survive when you copy the text into the Instagram app. This Post Generator is a visual mockup builder — it combines your image, profile picture, caption, and engagement numbers into a full-card preview that you can export as a PNG. Use the Line Break tool to fix caption formatting before publishing; use this tool to visualise or present an entire post.
How is this different from the Instagram Font Generator? expand_more
The Instagram Font Generator converts your text into Unicode lookalike characters (bold, italic, cursive, etc.) that you then paste into a real post caption or bio. This tool does not change your text at all — it places the text inside a rendered mockup of an Instagram post card for preview and export.
What post sizes does the tool support? expand_more
Three sizes: Square at 1:1 (1080×1080 px), Portrait at 4:5 (1080×1350 px), and Landscape at 16:9 (1080×608 px). These match the actual pixel dimensions Instagram uses for each format.
Can I use this for commercial purposes? expand_more
You can use the exported images for presentations, portfolios, and design projects. Creating mockups to deceive others or impersonate real accounts may violate platform terms of service and local laws, so use the tool responsibly.
What export resolution does the tool produce? expand_more
The export feature uses html2canvas at a 2x scale factor, which doubles the pixel density of the visible preview. The resulting PNG is sharp enough for slide decks and client presentations.
Is there a character limit for captions? expand_more
Yes — matching Instagram's own limit, the caption field accepts up to 2,200 characters. A live counter below the textarea shows you how many characters remain.
