Export & Sharing

NavSlides Editor supports multiple export formats so you can share your presentation in any context — live on the web, offline at a conference, or embedded in a document.

HTML export (standalone)

The default HTML export produces a self-contained .html file that loads reveal.js and other assets from a CDN.

• Open your presentation in the editor.
• Click File → Export → HTML.
• Save the .html file to your computer.
• Open the file in any browser to present.

TIP

Standalone HTML is the smallest file format because assets are fetched from a CDN at runtime. Use it when you expect an internet connection.

Offline HTML

Offline HTML inlines all external CSS, JavaScript, and font assets so the file works without any internet connection.

• Click File → Export → Offline HTML.
• The export process downloads all CDN assets and inlines them — this may take a few seconds.
• The resulting file is self-contained and can be copied to a USB drive or shared by email.

TIP

Use offline HTML when presenting at a conference venue where Wi-Fi may be unreliable, or when distributing slides to students.

PDF

Export a print-ready PDF using the browser's print dialog with reveal.js print styles applied.

• Click File → Export → PDF.
• The editor opens a print-optimized view in a new tab with all fragments expanded.
• Use Ctrl+P (or Cmd+P) and choose "Save as PDF" in the print dialog.
• Set margins to "None" for best results.

WARNING

PDF export relies on the browser's print engine. Complex layouts, custom fonts, or TikZ diagrams may render slightly differently than on-screen. Check the print preview before finalizing.

PPTX (PowerPoint)

Export a PowerPoint-compatible .pptx file for editing in Microsoft Office, Google Slides, or LibreOffice Impress.

• Click File → Export → PPTX.
• Text, images, and basic shapes are exported as editable PowerPoint elements.
• Complex elements (LaTeX blocks, charts) are rasterized as images in the PPTX.

Shareable links

Generate a shareable URL that others can open to view (or edit) your presentation directly in their browser — no installation required.

• Click Share → Get Link.
• Choose View only or Editable.
• Copy and share the URL.

TIP

Shareable links require your NavSlides Editor instance to be accessible from the internet (or your local network). If running locally behind a firewall, share the exported HTML file instead.

GitHub sync & hosting

Push your presentations to a GitHub repository and host them for free with GitHub Pages — no separate hosting setup required.

Setting up GitHub

1. Open any presentation and click the GitHub button in the top toolbar.
2. Enter your repository owner (your username or org) and repository name.
3. Create a Personal Access Token with repo scope and paste it into the token field.
4. Optionally set a Pages URL if you use a custom domain (e.g. https://yoursite.com/presentations). If left blank, it defaults to https://<owner>.github.io/<repo>.
5. Click Save Settings.

This configuration is saved once and reused across all your presentations.

Pushing a presentation

1. Click the GitHub button, enter an optional commit message, and click Push to GitHub.
2. NavSlides Editor exports a self-contained presentation.html and the raw presentation.json into a folder named after your presentation title.
3. All images and assets referenced in the presentation are uploaded alongside the HTML into an assets/ subfolder.
4. A README.md at the repo root is automatically generated with links to all your pushed presentations.

Each push creates a new commit, so you get full version history of every presentation in the repo.

Hosting on GitHub Pages

Once pushed, you can serve your presentations as a live website using GitHub Pages:

1. Go to your repository on GitHub → Settings → Pages.
2. Under Source, select the branch (usually main) and folder (/ (root)).
3. Click Save. GitHub will publish your site within a minute or two.
4. Your presentations are now live at https://<owner>.github.io/<repo>/<folder>/presentation.html.

The auto-generated README.md contains direct links to every presentation. You can share these links with anyone — they load instantly in any browser with no login or software required.

TIP

If you have multiple presentations in one repo, they each get their own folder. Push as many as you like — the README index updates automatically with every push.

Version history from GitHub

NavSlides Editor can also pull commit history from GitHub to browse and restore previous versions of a presentation:

• Click the History button (clock icon) in the editor toolbar.
• Browse past commits with timestamps and messages.
• Click any version to preview it, and restore it if needed.

This gives you git-backed version control in addition to the built-in snapshot system.
