What is img2dataset?

A tool often used by researchers and developers to scrape images and create large-scale image-text datasets for AI training.

A tool often used by researchers and developers to scrape images and create large-scale image-text datasets for AI training. img2dataset is an AI data-collection crawler operated by Open Source Community. It harvests web content to build or expand training datasets for large language models (LLMs). Unlike search crawlers, img2dataset does NOT influence your page ranking in any search engine. The user-agent string img2dataset can be safely blocked via robots.txt, meta tags (noai), or the emerging llms.txt standard without any SEO penalty. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

What happens if you block img2dataset?

✅ **No SEO Impact** - Blocking img2dataset does not affect your rankings in Google, Bing, or any other search engine. img2dataset is an AI training crawler, not a search indexer. You can freely block it via User-agent: img2dataset / Disallow: / without any SEO penalty. This is the recommended approach if you want to opt out of Open Source Community's LLM training datasets.
Generally safe to allow; provides legitimate crawling value.

How to block img2dataset with robots.txt

<code>User-agent: img2dataset</code> - Matching is case-insensitive. Robots.txt is fetched from the root of each subdomain separately.

Block completely (robots.txt)
User-agent: img2dataset Disallow: /
Allow all (robots.txt)
User-agent: img2dataset Allow: /
Block private only (robots.txt)
User-agent: img2dataset Disallow: /private/ Disallow: /api/ Disallow: /admin/ Allow: /
Nginx server block
# Nginx: Hard-block img2dataset if ($http_user_agent ~* "img2dataset") { return 403 "Bot blocked"; }
Apache .htaccess
# Apache: Hard-block img2dataset SetEnvIfNoCase User-Agent "img2dataset" bad_bot Order Allow,Deny Allow from all Deny from env=bad_bot
Meta robots tag
<meta name="robots" content="noindex, nofollow">
X-Robots-Tag header
X-Robots-Tag: noindex, nofollow

Is img2dataset safe to allow?

Yes, img2dataset is a **safe and legitimate** crawler. It is operated by Open Source Community, which publicly documents its crawler at an official URL and follows the Robots Exclusion Protocol (RFC 9309). The user-agent string img2dataset is verifiable via reverse-DNS lookup on the crawling IP addresses. You can safely allow it unless you have a specific reason to block (e.g., AI training opt-out or SEO tool visibility).
Verify by reverse-DNS lookup: legitimate img2dataset requests resolve to open-source-community's domain.

What does img2dataset do?

Understanding img2dataset's purpose helps you decide whether to allow or block it.

  • Collects web content for AI model training
  • Gathers data to improve language understanding
  • Scrapes text, code, and other content for datasets
  • May be used for chatbot and AI assistant development
  • Typically does NOT affect search engine rankings

Frequently Asked Questions

What is the official user-agent string for img2dataset?
The official user-agent string for img2dataset is: img2dataset. This is the exact string you must use in robots.txt, Nginx, Apache, or Cloudflare firewall rules to target this bot. User-agent matching in robots.txt is case-insensitive, but the string must be spelled correctly. You can verify that a request genuinely comes from img2dataset by performing a reverse-DNS lookup on the source IP - legitimate bots resolve back to their operator's domain.
Is img2dataset safe?
Yes, img2dataset is a **safe and legitimate** crawler. It is operated by Open Source Community, which publicly documents its crawler at an official URL and follows the Robots Exclusion Protocol (RFC 9309). The user-agent string img2dataset is verifiable via reverse-DNS lookup on the crawling IP addresses. You can safely allow it unless you have a specific reason to block (e.g., AI training opt-out or SEO tool visibility).
Will blocking img2dataset hurt my SEO?
✅ **No SEO Impact** - Blocking img2dataset does not affect your rankings in Google, Bing, or any other search engine. img2dataset is an AI training crawler, not a search indexer. You can freely block it via User-agent: img2dataset / Disallow: / without any SEO penalty. This is the recommended approach if you want to opt out of Open Source Community's LLM training datasets.
How do I block img2dataset in robots.txt?
Add the following lines to your /robots.txt file: 
User-agent: img2dataset
Disallow: /
This instructs img2dataset not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders. To only block specific sections, replace / with the path (e.g., Disallow: /blog/). Note: robots.txt is publicly readable - any bot or human can inspect it at yourdomain.com/robots.txt.
Does img2dataset respect robots.txt?
Yes - img2dataset is a well-behaved bot operated by Open Source Community. It fetches and parses /robots.txt before crawling any page, following RFC 9309.
How do I verify if img2dataset is crawling my site?
Search your web server access logs for the string img2dataset (case-insensitive grep: grep -i "img2dataset" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For img2dataset specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of img2dataset?
img2dataset crawls at a moderate rate. If you notice excessive traffic in your logs, you can add a Crawl-delay directive: 
User-agent: img2dataset
Crawl-delay: 10
(10 second delay between requests).
Can I block img2dataset from specific pages only?
Yes. Instead of a global Disallow: / you can restrict img2dataset to specific paths: 
User-agent: img2dataset
Disallow: /private/
Disallow: /staging/
Allow: /
This allows img2dataset everywhere except the listed paths. Path matching in robots.txt uses prefix matching - Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Does blocking img2dataset prevent AI training on my content?
Blocking img2dataset via robots.txt signals to Open Source Community that your content should not be used for AI training. However, robots.txt is a **voluntary** protocol - there is no technical enforcement. For stronger protection: 1. Add <meta name="img2dataset" content="noai, noimageai, noindex"> to your pages. 2. Add a llms.txt file at your domain root (emerging standard). 3. Use Cloudflare WAF or Nginx to return 403 for this user-agent. 4. Consider IP blocklists for Open Source Community's known crawler IP ranges.
Is there an alternative to robots.txt to opt out of img2dataset?
Yes. Several additional opt-out mechanisms exist for AI crawlers: • **Meta tag**: <meta name="img2dataset" content="noindex"> • **X-Robots-Tag HTTP header**: X-Robots-Tag: noai, noimageai • **llms.txt**: Add a /llms.txt file (similar to robots.txt but for LLMs) • **Server block**: Return 403 or 429 for this user-agent via WAF or Nginx Using multiple layers provides the strongest protection.
