CanvasPort

Take any Obsidian Canvas anywhere. CanvasPort is a local-first desktop plugin that turns Canvas files into self-contained HTML, PNG, JPEG, WebP, SVG, PDF, Excalidraw, Mermaid, or D2 without sending vault data to an external service.

Canvas in. Portable formats out. Export once for documentation, publishing, printing, presentations, or diagram-as-code workflows.

What CanvasPort does

• Exports one canvas to several formats in a single action.
• Applies one clear light, dark, or Obsidian-matched theme to every visual export.
• Creates PNG, JPEG, WebP, and SVG visuals for documentation and sharing.
• Converts Canvas structure into Excalidraw, Mermaid, and D2 diagrams.
• Keeps canvas groups, connections, text, file content, and labels in the rendered output where the target format supports them.
• Embeds images directly and places the first page of each Canvas PDF node into PDF exports at full vector quality.
• Lets you choose an output folder and safely overwrite, rename, or skip existing exports.
• Offers grid, group-label, transparent-background, image-scale, and image-quality controls.
• Lets visual exports match Obsidian’s current theme or use a fixed light or dark appearance.

Supported Obsidian Canvas export formats

Included test suite

The repository includes a self-contained Obsidian test dataset in tests/dataset/. It provides eight focused Canvas files, reusable image and document fixtures, and expected-result documentation for repeatable visual regression testing.

• Start with 00 - Test Suite Dashboard.canvas.
• Use reference/Expected Results.md for format-by-format acceptance checks.
• Record manual verification in reference/Test Run Template.md.
• Keep generated exports outside the dataset or in temporary test-output folders.

Install locally in Obsidian

CanvasPort requires the desktop version of Obsidian because image and PDF rendering use Electron APIs.

Install from a GitHub release

1. Download main.js, manifest.json, and styles.css from the latest release.
2. Create <your-vault>/.obsidian/plugins/canvasport/.
3. Copy the three downloaded files into that folder.
4. Restart Obsidian, open Settings → Community plugins, and enable CanvasPort.

Build from source

1. Download or clone this repository.

2. In the project folder, install Node.js dependencies and build the plugin:

   npm install
   npm run build
   

3. Create <your-vault>/.obsidian/plugins/canvasport/.

4. Copy the three files from build/ into that folder: main.js, manifest.json, and styles.css.

5. Restart Obsidian, open Settings → Community plugins, and enable CanvasPort.

Using the plugin

Open a .canvas file, then use one of these commands from Obsidian’s Command Palette:

• Export current canvas… — choose one or more formats and export options.
• Export to [format] — export directly to a chosen format.
• Re-export with last settings — repeat the last export selection.

You can also right-click a Canvas file in the file explorer and choose Export canvas….

Development

CanvasPort requires Node.js 20 or later and npm.

npm install
npm run verify

npm run verify validates publication metadata and test fixtures, runs Obsidian's official ESLint rules, checks TypeScript, executes exporter tests, and creates a production build. Use npm run dev to rebuild while developing. npm run build always writes a ready-to-copy plugin package to build/.
