How to: XML Sitemap Generator
- Paste your page URLs, one per line.
- Choose lastmod date, change frequency and priority options.
- Download sitemap.xml, upload it to your site and submit it in Search Console.
An XML sitemap is a list of the pages you want search engines to know about. It helps new sites get discovered, makes sure deep pages are not missed and signals when content changes. Fileopia’s generator turns any pasted list of URLs into a valid sitemap that follows the sitemaps.org protocol – cleaning duplicates, rejecting invalid lines, escaping special characters and adding optional lastmod, changefreq and priority values. Nothing is sent to a server.
Common uses
- Create a sitemap for a hand-coded or static website.
- Build a sitemap for a subset of pages, such as a new product range.
- Replace a broken or outdated sitemap from an old plugin.
- Submit important pages to Google Search Console and Bing Webmaster Tools.
- Prepare a sitemap during a site migration to speed up re-indexing.
Tips for best results
- Only include canonical, indexable pages that return status 200.
- Use full absolute URLs with https:// and the same host version everywhere.
- Keep lastmod honest – Google ignores it if it changes on every crawl.
- Add a Sitemap: line to robots.txt so all search engines find it.
- Regenerate the sitemap whenever you add or remove pages.
What search engines use
Google reads the loc and lastmod fields and ignores changefreq and priority. Bing uses lastmod as a hint too. The optional fields do no harm, which is why the generator offers them, but the real value of a sitemap is a clean, complete list of URLs you want indexed with accurate modification dates. A sitemap does not guarantee indexing – it is a discovery aid – but it often speeds it up on new and large sites.
Cleaning your URL list
Duplicate URLs, mixed http and https versions, trailing-slash inconsistencies and parameters such as ?utm_source make sitemaps noisy. The generator removes exact duplicates, can normalise trailing slashes, and skips lines that are not valid URLs, listing them so you can fix them. Ampersands and other special characters are escaped as XML requires, which prevents the most common “sitemap could not be read” errors.
Submitting your sitemap
Upload sitemap.xml to your web root so it is reachable at https://yoursite.com/sitemap.xml. Then add it in Google Search Console under Sitemaps and in Bing Webmaster Tools, and add a Sitemap: line to robots.txt. Search Console reports how many URLs were discovered and indexed, which is a handy health check. Resubmit after large changes; small ones are picked up automatically.

Frequently asked questions
Does it crawl my website?
No. A browser cannot crawl other sites, so you paste the URLs. Export them from your CMS, a spreadsheet or your analytics pages report.
How many URLs can a sitemap hold?
Up to 50,000 URLs and 50 MB uncompressed. For bigger sites, split into several sitemaps and list them in a sitemap index.
Do I need a sitemap for a small site?
Not strictly – Google can find well-linked pages – but it is quick to make and helps new pages get discovered faster.
What is lastmod?
The date the page content last changed meaningfully, in W3C date format such as 2026-10-25.
Can I include images or videos?
This tool creates a standard URL sitemap. Image and video sitemap extensions are not included.
Is XML Sitemap Generator really free?
Yes. Every tool on Fileopia is 100% free with no file limits, no sign-up and no watermarks. The site is supported by unobtrusive ads.

No. Fileopia processes your files directly in your browser using JavaScript. Your documents never leave your device, so they stay completely private.
