Problem
HTML-to-PPTX conversion often breaks the exact thing you liked.
A converter may produce editable PowerPoint objects, but spacing, fonts, layering, and rich HTML visuals can drift immediately.
Conversion can flatten rich visuals or misplace text.
Editable PPTX is less useful if the deck no longer looks right.
Editing HTML first keeps the original presentation design stable.
Workflow
The ProductStudio-style structure, focused on deck polish.
A clear sequence replaces the thin demo feel: open the HTML file, make precise slide edits, then export a portable deck.
02
Fix what conversion would break
Adjust text, images, page order, and overflow before any downstream export.
03
Export a clean deck
Download the revised HTML file and decide later whether PPTX is still needed.
Capabilities
The practical controls AI HTML decks need.
The tool stays narrow: final visual polish for a generated HTML deck, not another AI presentation generator.
Click-to-edit text
Select titles, bullets, captions, or labels and adjust copy, font size, emphasis, and color without touching code.
Image insert and positioning
Drop in a local image, keep it embedded in the deck, resize it, and nudge it into place.
Page management
Add, duplicate, delete, and reorder slides directly from the thumbnail rail.
Fit overflowing content
Reduce oversized text on the current slide when an AI-generated layout starts to overflow.
Block image export
Select a slide block and copy or download it as a PNG for reuse in documents, posts, or messages.
Clean HTML export
Export a single-file HTML deck that preserves the edited layout and embedded images.
Example
Edit before conversion changes the design
If the HTML deck already looks good, fix the presentation while the original layout is still intact, then decide whether downstream PPTX conversion is worth it.
Editing path
route-specific proof, not keyword swapping
1
Preserve original typography and spacing during final edits.
2
Copy selected blocks as PNG when a native slide file is unnecessary.
3
Keep the cleaned HTML deck as the source of truth.
Comparison
Built between AI generation and final delivery.
The product has a narrow job: keep the AI draft intact while a human fixes what needs visual judgment.
HTML to PPTX
Useful when a PowerPoint file is required, but formatting may change.
HTML to editable slides
Makes the HTML deck itself editable so the original visual style stays intact.
When PPTX still makes sense
Use PPTX when collaborators require PowerPoint-native review or corporate templates.
Use cases
For people who already have an AI-generated HTML deck.
The interface is built for the post-generation workflow: a usable draft exists, and now it needs controlled visual polish.
Preserve AI-generated HTML design.
Avoid broken conversion before client delivery.
Export clean HTML as the portable source file.
Copy selected blocks as images when native slide editing is not required.
FAQ
Questions before opening a local HTML deck.
Clear boundaries matter: this is a local browser editor for HTML decks, not a cloud storage or PPTX conversion system.
Can I edit text directly?
Yes. Open a sample deck or upload a local HTML file, click into the slide canvas, and edit text in place.
Can I change font size and color?
Yes. The editor includes text size, color, bold, and italic controls for quick final polish.
Can I move inserted images?
Yes. Inserted images can be resized from the canvas and nudged from the formatting panel.
Does it work with Claude-generated HTML?
Yes. Claude decks that use section, article, data-slide, or slide-like containers are split into editable pages.
Does it work with ChatGPT or Codex output?
Yes. The first version focuses on single-file HTML decks from AI tools such as ChatGPT, Codex, Cursor, Gemini, and Claude.
Will the design change after export?
The editor preserves the HTML structure and inline edits. Complex third-party scripts are removed for a safer single-file export.
Can I export to PPTX?
Not in the first version. The product is intentionally positioned as a safer direct HTML editing workflow before any PPTX conversion step.
Is my file uploaded to a server?
No. In this version, files are opened and edited in the browser. The landing page states this as a local-first workflow.
