A free sitemap diagram maker for planning a site's structure
- Free
- No sign-up
- Works offline
Lay the pages out as a tree, see how deep the navigation really goes, then press Present and walk stakeholders through the structure section by section.
Present reveals your sitemap diagram one step at a time, on its own.
This draws a visual sitemap — the tree of pages and sections you sketch when planning or redesigning a site. Free, no sign-up, kept in your browser.
To be clear about what it is not: it does not generate an XML sitemap file for search engines. That is a different job done by a crawler. This is the diagram you use to agree the structure with people, before anything is built.
Pages, sections and the depth problem
A sitemap diagram is a tree: the home page at the root, top-level sections beneath it, and pages beneath those. What makes it worth drawing is that depth becomes visible.
A page four or five clicks from home is a page most visitors never reach, and no amount of navigation design fixes structure that is genuinely too deep. Seeing the tree is usually what prompts a team to flatten it.
Group by what a visitor is trying to do, not by who owns the content internally. Sites organised around the org chart are the most common structural failure, and the diagram makes it obvious: one enormous branch where a department was, and a thin one where the customers actually go.
Planning a redesign, and agreeing it
The sitemap diagram is where a redesign gets agreed cheaply. Moving a box is free; moving a page after launch means redirects, lost links and a conversation about search rankings.
It is also the artefact that makes the URL structure visible before it is set. A tree that is clean on the diagram tends to produce URLs that are clean too, and those are difficult to change later.
Present it section by section
Press Present and the tree builds one section at a time, narrated — which is how you take a stakeholder through a proposed structure without them immediately looking for their own page.
How to make a sitemap diagram, start to export
Open the editor, put the home page at the top, then add each top-level section and the pages beneath it. Watch the depth as you go. Export a PNG or PDF for the proposal, or present the structure in the review.
Free, private, and offline
Diagramium is free and there is no paid tier. Draw, present and export PNG or SVG without an account; a free account unlocks the animated export formats — GIF, video and animated SVG.
Your diagram is stored in your own browser, not on a server. It keeps working with the network off, and nothing is uploaded unless you choose to publish it.
Frequently asked questions
Is this sitemap maker free?
Diagramium is free and there is no paid tier. Draw, present and export PNG or SVG without an account; a free account unlocks the animated export formats — GIF, video and animated SVG.
Does this generate an XML sitemap for search engines?
No. This draws the visual site-structure diagram used for planning. An XML sitemap is generated by crawling a built site and is a different tool entirely.
How deep should a website structure be?
Aim for any important page within three clicks of home. The diagram is where excessive depth becomes obvious, usually well before anyone has built the navigation.
Can I use this to plan a site redesign?
Yes, and it is the cheapest place to do it. Rearranging boxes costs nothing; rearranging live URLs costs redirects and rankings.
How do I show navigation versus page hierarchy?
Draw the page hierarchy as the tree, and note where navigation deliberately differs — a footer link into a deep page, for instance. Where the two disagree often is a sign the structure needs revisiting.
