Why this workflow
Edit Your HTML Slides Without Writing Code
A browser can display an HTML deck. A visual slide workspace lets you change the content, images, and page order before you share it.
- Update text and typography directly on the slide.
- Move or resize images and adjust supported solid backgrounds.
- Organize the presentation from the thumbnail rail.
Practical example
A Workspace for Your Existing HTML Presentation
Recognizable slide sections become individual pages you can select and edit.
Open a saved HTML deck with slide containers.
Select a slide and make a focused change.
Download revised HTML and reopen it for later edits.
A real HTML presentation
Explore the deck. Then make it yours.
Browse an eight-slide English presentation about design resources for Codex. Open the same file in the editor to change its text, images, and slide order.

Use Cases
Make the Changes Your Presentation Needs
Use the same visual workspace for AI-generated decks and HTML slides you have built yourself.
Update figures, labels, or copy in an existing report.
Replace or reposition a local image before a presentation.
Reorder slides and save a revised version for sharing.
Process your deck in your browser
Open, edit, and export your HTML file without sending the deck to a conversion server. No account is required. Remote images or fonts referenced by your HTML may still request their original hosts.

HTML Presentation Editing FAQ
What you can change, how to save it, and which files to bring.
Do I need coding experience to edit HTML slides?
No. Click supported text in the canvas to edit it, use the formatting controls, and move images visually without writing HTML or CSS.
What elements can I edit in my HTML deck?
You can edit text, font size, emphasis, color, supported solid backgrounds, and local images. You can also add, reorder, duplicate, or delete slides. Fit text reduces text size on the current slide; check whether further changes are needed.
How do I save or present my edited HTML presentation?
Export HTML downloads a single-file presentation with slide navigation and fullscreen playback. You can also export a static PPTX with editable text and shapes where supported.
Can I re-import the exported HTML file later?
Yes. Save the exported HTML file and open it again for further editing. Changes in an unsaved browser session are not a substitute for downloading your file.
Why do some scripts or animations look different?
Import removes source scripts and unsafe embedded content. Layouts that depend on JavaScript may need preparation. HTML export includes a built-in player, while PPTX export is static; neither preserves every custom runtime effect.
Can I upload a .pptx file to edit directly?
The input must be an HTML presentation file. SlideBeaver does not import native .ppt or .pptx files, turn screenshots into editable text, or generate a presentation from a prompt.
Are my presentation files kept private?
Your HTML file is processed in your browser, not uploaded to a conversion server. External images and fonts referenced by the file may still need a network connection.
Open Your HTML Presentation and Make It Yours
Bring a local HTML file, make your changes, and download the revised deck.
