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.

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.

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.
