Paste the HTML
Bring the content fragment or document body you want to convert. The tool treats it as untrusted input.
Gixo Lumen · deterministic document conversion
Turn HTML into reviewable PowerPoint slides while stripping the parts that should never become slide content.
Paste a fragment or document body, see the sanitized structure as slides, and inspect the result before download. Headings, lists, tables, and text become slide content; scripts and presentation-only styling do not.
Editable slides, not screenshots
Free preview, no account required
Structure read from your source
Your wording kept
PPTX and PDF export
Stable layouts export as editable PowerPoint text and shapes; complex slides export as images that keep their appearance, so their text cannot be edited separately.

Real slide text, tables, and extracted structure
A pasted HTML fragment or document body containing headings, lists, tables, and text.
Review every slide in the browser for free, without an account. Sign in only when you want to download PPTX or PDF.
Input
Scripts, styles, iframes, event handlers, and external resources are removed before extraction.A converter, not a prompt box
Turn the structure you already have into a slide preview.
HTML to PowerPoint is a content-structure converter, not a browser screenshot tool. It deliberately leaves web-only styling and behavior behind.
The conversion step is deliberately structural. It extracts the source, identifies headings and blocks, and splits long sections into readable slides — it does not paraphrase your source or invent a narrative around it. Rewriting, restructuring and theming are separate, opt-in steps you take afterwards in Lumen.
Free preview: convert and inspect the complete deck in your browser without an account. Sign in is the download boundary for PPTX and PDF.
How it works
Three bounded steps from pasted HTML to slides.
Sanitize and structure
Scripts, styles, iframes, and event handlers are removed; headings, lists, tables, and text blocks are normalized.
Inspect before download
Review all slides, then export to PPTX or PDF when the structure looks right.
Source rules
What the converter reads from pasted HTML.
HTML is sanitized first. H1–H3 headings become boundaries, lists become bullets, tables receive their own slide, and active or presentation-only markup is removed.
Sanitization
The fragment is cleaned before any structure is inferred. Active elements never become slide content.
Headings
H1–H3 headings define slide boundaries; the parser does not need a model to guess which paragraph is a title.
Tables
Tables are isolated onto their own slide so row and column relationships remain inspectable.
Output behavior
What stays faithful, and what does not.
Preserved or represented
- H1, H2, and H3 heading hierarchy
- Ordered and unordered lists
- Native table structure
- Text content after HTML sanitization
Outside this batch
- Scripts, styles, iframes, and event handlers
- Pixel-perfect reproduction of a web layout
- AI rewriting or design generation
- External resources being fetched as part of the paste
Supported formats & specifications
The contract we can state today.
Benchmark pending for this input; limits are not guessed on this page.
| Aspect | What to expect |
|---|---|
| Input | pasted HTML |
| Result | Full deck preview in the browser, including slide count, source-page count, and extraction warnings. |
| Free vs signed in | Preview is free without an account. Sign in to download PPTX or PDF, apply a brand kit or theme, or restructure the narrative with AI. |
| Measured limits | Benchmark pending for this input; limits are not guessed on this page. |
| Extraction | Structural, not generative: headings, blocks and tables are read from the source rather than rewritten. |
| Safety | Uploads are validated and bounded-parsed. URL conversion accepts public HTTP/HTTPS pages only. |
What conversion does, and what it leaves to you
Structure is extracted. Judgement stays yours.
Conversion reads the structure already in your source and lays it out as slides. The complete preview is free without an account; downloading, brand kits, theming, and AI restructuring begin after sign-in. Nothing is silently reworded between the file you brought and the deck you present.
A note about HTML fidelity: The preview is the authority for the converted structure: web-only CSS and behavior are intentionally not represented as slide content.
Details
What pasted HTML to PowerPoint conversion includes
See what the free converter does, what remains unchanged, and where the full Lumen workflow begins.| Topic | Details | What to know |
|---|---|---|
| Input | pasted HTML | The source format determines which structural signals the converter reads. |
| Review | Every slide appears in the browser preview before export. | You can inspect the output before anything leaves the workspace, then edit the downloaded PPTX in PowerPoint. |
| Free preview | Full deck preview without an account. | Slide count, source-page count, and extraction warnings are visible before sign-in. |
| Export | PPTX and PDF after sign-in, with editable text and native tables on stable layouts. | Stable layouts export as editable PowerPoint text and shapes; complex slides export as images that keep their appearance, so their text cannot be edited separately. |
| Method | Structural extraction and slide assembly, not paraphrase. | The same source structure produces the same conversion behavior. |
Does HTML to PowerPoint preserve CSS?
No. Styles, scripts, iframes, and event handlers are stripped before conversion. The result preserves content structure rather than browser layout.
Is pasted HTML safe to convert?
The converter sanitizes the input before reading it and treats the source as untrusted data. Active markup is not executed as part of the conversion.
Can HTML tables become editable PowerPoint tables?
Tables are represented as their own structured slide. Inspect the result in the preview before exporting to confirm the exact layout.
Does the converter use an AI model?
No. HTML sanitization, heading detection, slide splitting, and output assembly are deterministic.

Ready to inspect the result?
Convert pasted HTML to PowerPoint and review the slides before you export.
Reviewing is the point: you can see whether the source structure made a useful deck before anything is exported, then edit the downloaded file in PowerPoint.
