Export NotebookLM Mind Maps to Offline HTML, Images and Editable Files
Export HTML, PNG, SVG, Markdown, FreeMind, OPML and JSON for free. Choose a whole map or one branch. Free batches allow 5 items; Pro removes that batch limit.
NotebookLM Ultra Exporter · Updated
Open the export entry on a NotebookLM mind map, wait for the extension to read its available content, then follow Choose output → Confirm content → Download. Offline interactive HTML is selected by default. All seven single-map formats are free without a daily export quota.
Can I export a whole map or one branch?
The whole map is selected by default. Choose one branch to include that node and all its available descendants, with the parent path as context. Parent paths distinguish branches with the same name. Preview and download use the same scope. You can change the filename and choose a white or transparent background for PNG / SVG.
The extension reads available tree data first. Changes to the data source or Google's page can make the full range uncertain. Check the actual read counts, preview and any specific warnings, then reload if needed.
Which formats can I export? (same on Free and Pro)
| Format | Use |
|---|---|
Interactive HTML .html | One self-contained offline file for desktop browsers: expand / collapse, search, pan, zoom and locate parent paths; recipients need no account |
OPML .opml | Structured outline; import where the target tool supports OPML |
FreeMind .mm | Keep organizing in compatible mind-mapping software |
Markdown .md | Save to a notes tool as headings and lists |
JSON .json | Keep the tree structure for later processing |
SVG .svg | Vector graphic with automatic layout |
PNG .png | Image with automatic layout for sharing and document illustrations |
None of these formats use the 5-per-day premium quota. PNG does not consume a long-image export. Images preserve the original text, hierarchy and sibling order with automatic layout. If a map is too large for a clear PNG, choose SVG / HTML for free. Target applications differ in their OPML / FreeMind import, style and layout support.
How do I export several maps together?
Choose Batch export in the single-map dialog to open the current notebook's maps, or use the existing workspace / Studio batch entry. Choose one format for the selected maps. Each map produces one file; multiple files use ZIP.
Free allows 5 selected results per batch; Pro removes that batch limit. Mixed batches count all selected results, including other content. Counts apply to results, rather than nodes, branches or ZIP file entries. An oversized selection is preserved so you can reduce it or upgrade and continue. Retry only failed items when needed. Existing PDF quotas for reports / flashcards and other content still apply in mixed batches.
