OpenPresentation -- Presentation Tool¶

OpenPresentation is a super simple, free presentation tool that runs entirely in your browser. Built with vanilla JavaScript as part of the OpenSuite project, OpenPresentation makes it easy to create and present slides -- no sign-up, no installation, no complicated software. Just open it and start building your presentation.

Themes¶

OpenPresentation includes 15 built-in themes across four categories:

Professional	Modern Blue, Corporate Gray, Executive Dark, Clean White
Creative	Sunset Gradient, Neon Pop, Pastel Dream, Forest Green
Academic	Classic Serif, Minimal Scholar, Research Paper
Bold	Red Impact, Electric Purple, Midnight Gold, Ocean Teal

Applying a theme updates the background, text colors, fonts, and accent colors across all slides. The theme intelligently detects titles (large text) vs body text and applies appropriate styling.

Theme Generator¶

Create your own custom themes with the built-in theme generator:

Pick background, title, body, and accent colors using color pickers
Choose title and body fonts from the dropdown
See a live mini-preview update in real time
Click Apply to apply to your presentation
Click Save Theme to save for future use

Custom themes are stored in your browser's localStorage and appear alongside built-in themes in the theme picker.

Basic: Fade, Dissolve, Cut
Directional: Slide Left/Right/Up/Down

OpenPresentation uses the same storage system as OpenSheets and OpenDocs:

Browser storage: Your presentation auto-saves to localStorage every 2 seconds
URL sharing: Click "Save & Share" to encode your presentation into a shareable URL (as a compressed base64 string)
Independent workspaces: Each shared link recipient gets their own browser cache key
No account needed: Everything runs in the browser

Click File > Save & Share
Your presentation is serialized, compressed, and encoded as a base64 string in the URL hash
The URL is automatically copied to your clipboard
Send the URL to anyone -- they can open it and see your presentation
The recipient gets their own workspace and can edit independently

Save your share link

Your presentation is stored in your browser's localStorage. If you clear your browser data or switch to a different browser, your local copy will be lost. Always keep your share link -- it contains your complete presentation and serves as your backup. If you lose both your browser storage and your share link, your data cannot be recovered.
