## Pricing

from $0.20 / 1,000 image listeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Page Images Extractor: image URLs, alt text, sizes, lazy src

Every image on a web page, up to 500 pages a run and 1,000 images each: absolute URL, alt text, title, width and height, format, lazy source, srcset, whether it sits in a link, plus per page the counts of images and images without alt text. Robots-aware, no browser, no downloads. Pay per image.

### Why this scraper

- **Only delivered results are charged.** Inputs that fail come back as clear error
  records at no cost.
- One plain fetch per page, parsed with lxml, no browser, no start fee and nothing downloaded. Measured on the platform: 32 images from three pages (a Wikipedia article, BBC News, python.org) in 6 seconds for a sixth of a cent.
- Every image as a usable row: the absolute URL (relative paths and `<base>` resolved), alt text with a separate missing-alt flag, title, width and height attributes, format from the URL, whether it is lazy-loaded and from which attribute, srcset candidate count and the largest candidate, whether the image sits inside a link and where that link goes, host and internal or external, and how often the page repeats it.
- Page totals on every row: unique image count, images without alt text and inline data: images, so an accessibility or SEO audit reads off the first row per page.
- Robots-aware: each host's robots.txt is read once per run and a closed path comes back as a free `ROBOTS_DISALLOWED` row (measured: Google's `/search` path).

### Who this is for

Paste page URLs in `urls` (up to 500 per run) and set `maxImagesPerPage` (default 200, ceiling 1,000, page order). Switch `includeDataUris` on to see inline base64 images as rows with their length. Built for alt-text and accessibility audits, image SEO checks, finding oversized or lazy-loaded images, building image inventories of a site and seeding download or vision pipelines with clean URLs.

### Who this is not for

No browser is used, so images that a page adds with JavaScript after loading are not seen; lazy-loading attributes in the HTML are read, scripts are not run. Only `<img>` elements count: CSS background images, `<picture>` sources without an `<img>`, videos and SVG drawn inline are not rows. `width` and `height` are the HTML attributes, not the pixel size of the file; `format` is read from the URL and empty when the URL has no extension or format parameter (measured: 1 of 32). Nothing is downloaded, so file sizes are not known. A page without any image comes back as a free `NO_IMAGES` row.

### Input fields

| Field | Type | Required or default | What it does |
|---|---|---|---|
| `urls` | list of text | required | One per row, up to 500: full page URLs (https://...). Each host's robots.txt is respected. |
| `maxImagesPerPage` | number | 200 | Cost ceiling per page, in page order. |
| `includeDataUris` | true/false | false | On: inline base64 images are delivered with their length instead of a URL. Off (default): they are counted but skipped. |

### Input example

```json
{
    "urls": [
        "https://en.wikipedia.org/wiki/Web_scraping",
        "https://www.python.org/"
    ],
    "maxImagesPerPage": 200,
    "includeDataUris": false
}
```

### Output example

| Field | Type | What it holds | Example |
|---|---|---|---|
| `pageUrl` | text | The page this image was found on. | `https://en.wikipedia.org/wiki/Web_scraping` |
| `position` | number | The place in the source's own order, counting from 1. | `1` |
| `url` | text | The image file itself, made absolute. | `https://en.wikipedia.org/static/images/icons/enwiki-25.svg` |
| `altText` | text | The alt text, which is what a screen reader says and what search engines read. Empty is the finding, not a gap in our data. | `Wikipedia` |
| `hasAlt` | true/false | Whether the image has an alt attribute at all, which is not the same as having text in it. | `False` |
| `title` | text | Filled when the image carries a title attribute, the text shown on hover. |  |
| `width` | number | Filled when the img tag states a width; many pages leave the size to CSS. | `50` |
| `height` | number | Filled when the img tag states a height; many pages leave the size to CSS. | `50` |
| `format` | text | Read from the file extension, for example jpg or webp; 'data' for an image embedded in the page. | `svg` |
| `isLazy` | true/false | Whether the page loads the image late, through loading=lazy or a data-src placeholder. | `False` |
| `lazySource` | text | The real image behind a lazy placeholder; empty when the image loads normally. |  |
| `srcsetCount` | number | How many alternative sizes the page offers for this image; 0 when it offers none. | `0` |
| `srcsetLargest` | text | The largest of those alternatives, which is usually the one worth downloading. | `https://thumb.wikimedia.org/wikipedia/en/thumb/9/99/Quest...` |
| `inLink` | true/false | Whether the image sits inside a link, which makes it a button rather than an illustration. | `True` |
| `linkUrl` | text | Where that link goes; empty when the image is not inside one. | `https://en.wikipedia.org/wiki/Main_Page` |
| `domain` | text | The domain the image is served from, which shows whether a site hosts its own images. | `en.wikipedia.org` |
| `isInternal` | true/false | Whether the image is hosted on the same registered domain as the page. | `True` |
| `occurrences` | number | How often the same image URL appears on the page; a repeated logo counts once with a higher number here. | `1` |
| `pageTitle` | text | The title of the page the image was found on. | `Web scraping - Wikipedia` |
| `pageImageCount` | number | How many images the page has in total, repeated on every row. | `10` |
| `pageMissingAltCount` | number | How many images on the whole page have no alt text, repeated on every row so one row carries its own context. | `3` |
| `pageDataUriCount` | number | How many images are embedded in the page itself rather than loaded; these are skipped unless includeDataUris is on. | `0` |

Error codes: `INVALID_URL`, `ROBOTS_DISALLOWED`, `NOT_HTML`, `NO_IMAGES`, `FETCH_FAILED`, `BLOCKED`.

One delivered row looks like this:

### Pricing

Pay per event: one `image-listed` event per delivered result. No charge for inputs
that fail, no separate platform-usage surcharge.

**Free Apify plan:** this actor delivers up to 25 rows per run for accounts on the Apify free
plan, and then stops with a message. That limit is set by us, not by Apify. It exists so the
actor keeps paying for itself for the people who do pay. Any paid Apify plan runs it at full
size, billed per delivered row, with failed rows never charged.

**Reviews:** if this actor saves you time, a short review on this page is the one thing that
helps most. Ratings are what other buyers look at first, and we have no other way to ask.

### Use with AI agents

AI assistants such as Claude, ChatGPT or Cursor can run this actor through Apify's own MCP server. Ask for the actor `steadydata/page-images-extractor` by its full name, so the assistant does not pick a different one, and start from this minimal input:

```json
{
  "urls": [
    "https://en.wikipedia.org/wiki/Web_scraping",
    "https://www.python.org/"
  ]
}
```

The assistant can read the price per event from the Pricing section above before the first paid run. Failed input comes back as an error row, as described above.

### FAQ

**Is personal data collected?**
No. Image URLs and alt texts are what the page publishes; the actor reads only the URLs you give it and downloads no image.

**How do I find images without alt text?**
Filter on `hasAlt` false. `altText` is empty both when the attribute is missing and when it is an empty string (decorative images); `hasAlt` is false in both cases, and `pageMissingAltCount` on the page row gives the total.

**Which URL is delivered for a lazy-loaded image?**
The real source: when `src` is empty or a placeholder data: image, the lazy attribute (data-src, data-lazy-src, data-original and the like) or the first srcset candidate is used, and `lazySource` shows it. `srcsetLargest` gives the biggest candidate for high-resolution needs.

**Can it download the images?**
No, by design; it lists them. Feed the `url` column to a downloader of your choice.

**What does a run cost when a page fails?**
Nothing. `ROBOTS_DISALLOWED`, `NOT_HTML`, `NO_IMAGES`, `FETCH_FAILED`, `INVALID_URL` and `BLOCKED` rows are free; only delivered images are charged.

**What happens when the source changes?**
Sources change from time to time; that is the nature of this work. The actor is
monitored daily and fixed fast, and while it is broken you are not charged, because
only delivered results cost anything.

**Can I call it from my own code, like an API?**
Yes. Every run is available through the Apify API: start it with one HTTP request, then read
the results as JSON, CSV or Excel from the dataset endpoint, or use the official Python and
JavaScript clients. The input is the same JSON as in the input example above, so a scheduled
script, a Make or Zapier step or an AI agent can call it without any changes.
