Image Sitemap Generator, Get Your Images Indexed by Google
Pair each page URL with the images it contains, add optional titles and captions, and export a spec-valid image sitemap Google can crawl to surface your pictures in Google Images. Validated live, generated entirely in your browser. No crawl, no upload, no signup.
What is the image sitemap generator?
The Image Sitemap Generator pairs each page URL with its hosted images and emits a valid Google image sitemap using image:image, image:title and image:caption, escaping XML-unsafe characters. Live validation flags non-HTTPS or duplicate image URLs and the 1,000-per-page and 50,000-URL limits. Free and browser-based, so CDN-hosted assets never leave your machine.
The GigAI Image Sitemap Generator builds a Google image-extension sitemap: an XML document where every <url> points at a page and lists the <image:image> entries hosted on it, so Googlebot can discover pictures that lazy-loading, CSS backgrounds, JavaScript galleries or CDN hosting would otherwise hide. Group your image URLs under the page that displays them, add an optional <image:title> and <image:caption> per image, and the tool emits a well-formed <urlset> that declares the xmlns:image namespace Google requires. As you type it validates the result, flagging pages with no images, non-HTTPS or non-absolute image URLs, duplicate image locations, and warning before you approach the 1,000-images-per-page and 50,000-URL protocol limits. XML-unsafe characters in URLs, titles and captions (&, <, >, quotes) are escaped automatically, so the file always parses. When it looks right, copy the XML or download image-sitemap.xml, place it at your domain root, and submit it in Google Search Console or reference it from robots.txt. Unlike crawler-based tools that spider your live site on a server (and cap free plans), this runs 100% in your browser from the image URLs you already have. There is no page limit we impose, nothing is uploaded, and unpublished or CDN-hosted assets never leave your machine.

How to use the image sitemap generator
- 1
Add a page URL
Start each block with an absolute page URL on its own line. This becomes the <loc>: the page Google associates the images with.
- 2
List its images beneath it
Indent (or prefix with '- ') each image URL on the following lines. Optionally append a title and caption: image-url | Title | Caption.
- 3
Review validation
Watch the live status: pages, total images, HTTPS coverage, duplicates and any per-page or protocol-limit warnings. Fix flagged rows before you export.
- 4
Copy or download image-sitemap.xml
Copy the XML or download image-sitemap.xml, upload it to your domain root (e.g. https://example.com/image-sitemap.xml), and submit that URL in Google Search Console.
- 5
Reference it from robots.txt
Add a 'Sitemap: https://example.com/image-sitemap.xml' line to robots.txt so every crawler discovers it automatically, not just Google.
What Image Sitemap Generator includes
Page → images, one valid sitemap
Group image URLs under the page that hosts them and get a Google image-extension <urlset> with the xmlns:image namespace, escaped locations and clean indentation.
Optional titles and captions
Add an image:title and image:caption per image inline (image | Title | Caption) to give Google richer context for Google Images ranking and previews.
Live protocol validation
As you type we flag pages with no images, non-absolute or non-HTTPS image URLs, duplicate image locations, and warn before the 1,000-image-per-page and 50,000-URL limits.
Automatic XML escaping
Ampersands, angle brackets and quotes in image URLs, titles and captions are escaped for you, so the sitemap is always well-formed and never rejected as unreadable.
Copy or download image-sitemap.xml
One click copies the XML or downloads a correctly-named image-sitemap.xml. Drop it at your site root and submit it in Search Console.
100% in your browser
No crawler, no server, no page cap. Your image URLs (including CDN-hosted and unpublished assets) are turned into XML locally and never uploaded, stored or logged.
Why use our image sitemap generator
Surface images Google can't find
Lazy-loaded, JavaScript-rendered, CSS-background and CDN-hosted images are often missed by the crawler. An image sitemap points Google straight at them.
Win traffic from Google Images
Image search is a real discovery channel for recipes, products, portfolios and how-tos. Titles and captions give Google the context to rank and preview them well.
Ship well-formed XML every time
Automatic escaping and live validation mean the file you download parses cleanly in Search Console. No 'could not read your sitemap' errors.
Keep unpublished assets private
Nothing is crawled or uploaded, so you can build a sitemap that references pre-launch, staging or CDN URLs without exposing them to a third party.
Built for the way you work
From quick one-off fixes to daily workflows, see how people put this tool to use.
- E-commerce / product SEO
Index every product photo
List each product page with its gallery image URLs, titles and captions so product shots can rank in Google Images and drive shopping discovery.
- Photographer / portfolio
Get a JavaScript gallery crawled
Lightbox and infinite-scroll galleries hide images from the crawler. An image sitemap lists every full-resolution URL explicitly so none are missed.
- Publisher / blogger
Add rich context to article imagery
Give diagrams, infographics and hero images descriptive titles and captions so Google understands and previews them in image results.
- Agency / freelancer
Map CDN-hosted images to their pages
When images live on a separate CDN or subdomain, an image sitemap ties them back to the page URL that displays them, privately, with no third-party crawl.

Common problems, solved
Hit a snag? Here are quick fixes for the issues people run into most.
Search Console says my image sitemap couldn't be read.
Confirm the file is reachable at the URL you submitted (open it in a browser), is served as XML/text, and that it declares the image namespace (xmlns:image). This tool emits that namespace automatically, re-download if you hand-edited the file.
My images still aren't showing in Google Images.
A sitemap aids discovery, not guaranteed indexing. Make sure the image URLs return HTTP 200 and aren't blocked by robots.txt, that pages aren't noindex, and that images have relevant alt text and load fast. Then allow days-to-weeks for recrawl.
Some image lines were skipped.
Every image must be an absolute URL like https://example.com/photo.jpg. Relative paths (/img/photo.jpg) and non-http(s) entries are skipped and flagged. Fix or remove the highlighted lines.
One page has hundreds of images: is that ok?
Google allows up to 1,000 images per page in the sitemap. The tool warns as you approach it. If you exceed it, keep the most important images or split the gallery across paginated page URLs.
Get the most out of it
Only list images you actually want in Google Images, decorative icons and spacers add noise and waste crawl attention.
Use absolute HTTPS image URLs. Relative paths and http:// entries are flagged and can be rejected by Search Console.
Write real, human-readable titles and captions. They help Google understand the image and can appear alongside it in results.
You can list images hosted on a different domain or CDN, but you must verify that host in Search Console for them to be attributed.
Combine this with a standard URL sitemap: a page sitemap for crawling and an image sitemap for image discovery cover both bases.
