Click a node to select · Double-click to rename · "+ Child" adds a child · Drag nodes to rearrange · Scroll/pinch to zoom · Pan by dragging empty space

Saved Maps

All maps are stored in your browser (IndexedDB). They persist across page reloads without any account.

How it works

SVG canvasNodes and connectors are drawn as SVG elements — no canvas API, no raster blurring when you zoom.
IndexedDB storageYour maps are saved in your browser's IndexedDB — the same technology used by offline PWAs. Nothing is sent to any server.
Drag & dropDrag any node by its label to reorganise the tree. The connector curves update instantly.
ExportPNG uses an SVG→Canvas→PNG pipeline. SVG downloads the raw vector file. JSON exports the tree data so you can reload it later.

Keyboard shortcuts: Tab adds a child to the selected node · Enter adds a sibling · F2 renames · Delete removes

Frequently asked questions

Do I need to create an account to use this mind map tool?
No. The tool runs entirely in your browser using HTML, SVG, and JavaScript. There is no login, no registration, and no email required. Your maps are saved to your browser's local IndexedDB storage, so they persist across sessions on the same device without any server involvement. You can open the page while offline and it will still work fully.
Where are my mind maps stored — will I lose them if I clear my browser?
Maps are stored in IndexedDB, which is part of your browser's local storage. They survive normal browser restarts and tab closures. However, if you use your browser's "Clear site data" or "Clear browsing data" option and include IndexedDB / local storage, they will be erased. To prevent data loss, use the JSON export button to save a backup file to your computer — you can reload it at any time with the "Load JSON" button.
How do I add child nodes and build a tree?
Click any node to select it (it will highlight with a glow). Then click + Child in the toolbar (or press Tab) to add a child node directly connected to it. To add a node at the same level as the selected node, click + Sibling (or press Enter). Double-click any node label — or select it and press F2 — to rename it inline. Drag a node by its circle or label to reposition it anywhere on the canvas.
What export formats are available and what are they good for?
PNG produces a raster image suitable for presentations, documents, or sharing on social media. SVG exports a scalable vector file that stays crisp at any size — ideal for printing or further editing in Inkscape or Illustrator. JSON saves the raw tree data so you can re-import it into this tool later, share it with a colleague who uses the same tool, or process it programmatically.
Is the mind map tool free forever?
Yes. This tool is part of Knackpad's suite of free browser-based utilities. There is no paid tier, no usage limit, and no feature locked behind a subscription. The source is a single self-contained HTML file — you can even save it from your browser and use it completely offline without visiting this website.
