Star Rating Maker (Free Image Generator)

Set a value like 4.3 in a star rating maker, set the max (usually 5), choose an icon and colors, and download a PNG or SVG. It's for review scores in emails, product cards, and social images, not a live widget inside your app.

What a star rating showsWhat a star rating shows

A rating is a row of icons filled up to a number. If you also want stars in search results, that comes from AggregateRating structured data on the page, not from the image. Two values define it. The value is the score, and it takes fractions like 4.3. The max is how many icons sit in the row, usually 5, though "8.6 of 10" tallies work fine too.

The interesting part is the last icon. When the score is fractional, one of three partial settings decides how it fills:

• exact: the last star fills proportionally, so 4.3 leaves a fifth star about a third full.
• half: the score rounds to the nearest half star.
• rounded: the score rounds to a whole star.

Beyond that you pick the shape (star, heart, circle, or a custom emoji), the active and inactive colors, and whether empty icons are solid gray or hollow outlines. You can also switch on a numeric label like 4.3, 4.3/5, or 4 of 5. The star is the default because it reads as a score at a glance, a convention that goes back to the star classification systems used for grading things long before the web.

An image is a snapshot for humans to read: a rating in a marketing email, a badge on a landing page, a score in a Slack digest. It isn't an interactive control. If you need clickable stars, build a widget. If you need a picture of a score, an image is the right tool.

Open the star rating maker. Set the value and max, choose stars or hearts, pick your colors, and download. No signup, no watermark. Export a PNG for emails and docs, or an SVG when you want it crisp at any size.

The input is generic on purpose. Give it a value and a max and it draws the row. Product, seller, recipe, app: none of that matters to the picture. If you have a score, you get a rating.

Embed it anywhereEmbed it anywhere

A rating image embeds like any other image. One line of HTML and it renders inline:

<img
  src="https://your-render-url?value=4.3"
  alt="4.3 out of 5 stars"
  width="180"
/>

This is the part worth knowing. Point at a render URL rather than a saved file and the row redraws on each load. Put it on a product card or in a review email and pass the value per product at request time. The score follows your average, and no one re-exports it.

Save a static file when you want a fixed snapshot, like a rating frozen in a printed report. Use a render URL when the stars should follow the live number.

Generate at scaleGenerate at scale

One badge by hand is fine. One per product across a catalog, or a fresh score each morning, is where the API does the heavy lifting.

Rating is a first-class API component, so a badge is something you configure once and render on demand. One call sets the value, max, icon, and colors, then returns the image. A few ways people wire it up:

• Per product: your catalog page renders each card's stars from that product's current average.
• On a schedule: a weekly job pushes the support team's CSAT score into a Monday email as green stars.
• Through an AI agent over MCP: the agent reads the score and calls the render itself, you stay out of it.

The API docs come with examples that run, so you copy the request instead of guessing it. Set the badge up once, then feed it scores.

• Build one now in the star rating maker, free, PNG or SVG.
• Configure it as an API component and render per product on demand.
• Automate it through the API or an AI agent.

The free plan covers 100 renders a month, enough to wire up a batch of product badges and see them land before deciding.
