Why SlideKiln

Everything the deck does, your browser does

Pixel-faithful rendering

All 187 preset shapes, custom geometry, text cascades, tables, effects and fills — parsed straight from OOXML with no conversion middlemen.

Animations & Morph

The full timing engine ships with every package: entrances, emphasis, motion paths and Morph transitions play back exactly as authored.

Real font metrics

Server-side text layout with true font metrics and an embedded font service, so line breaks land where PowerPoint put them.

Charts & SmartArt

Native chart rendering and SmartArt support, including embedded video and audio with transcode controls.

Built for automation

REST API with idempotency keys, signed upload URLs for big files, HMAC-signed webhooks and correlation ids.

Team-ready

Organizations with roles and invites, per-key usage attribution, and usage-based billing that scales with you.

Three ways in, one perfect package out

1

Drop a file in the dashboard

Drag a .pptx into the converter, watch the job progress live, and download the package when it lands.

2

Or call the API

Create an API key, POST the file (or a source URL), poll the status endpoint or receive a signed webhook.

3

Host the package anywhere

The output is a self-contained bundle of HTML, SVG, CSS and JS — a static folder any CDN can serve.

curl -X POST https://api.slidekiln.com/v1/jobs \
  -H "Authorization: Bearer sfk_your_api_key" \
  -F "file=@quarterly-review.pptx"

# → { "jobId": "8b1f…", "statusUrl": "/v1/jobs/8b1f…" }

FAQ

Questions, answered

What does SlideKiln actually produce?

A self-contained package of HTML, SVG, CSS and JavaScript that renders your PowerPoint deck in any modern browser — no PowerPoint, no plugins, no third-party viewer. You can host it on any static host or CDN, embed it in your site, or ship it inside your product.

How is this different from embedding a deck with Google Slides or an iframe viewer?

Embedded viewers rasterize slides or approximate them, and they keep your content on someone else's servers. SlideKiln parses the PPTX file format (OOXML) directly and rebuilds each slide as native web elements — real text, real vector shapes, real fonts — so the output is crisp at any zoom level, selectable, and entirely yours.

Do animations and transitions survive the conversion?

Yes. SlideKiln ships a full animation runtime with every package: entrance, emphasis and exit effects, motion paths, slide transitions and PowerPoint's Morph transition all play back as authored, with click-through navigation like a real presentation.

What happens to fonts?

Text is laid out server-side with real font metrics, so line breaks land where PowerPoint put them. Licensed fonts you can't redistribute are substituted with metric-compatible equivalents (for example Calibri → Carlito) and every substitution is reported in the conversion result.

Can I automate conversions from my own product or pipeline?

Yes — that's the primary use case. Create an API key and POST a .pptx (or a source URL) to the REST API. You get a job ID to poll, or an HMAC-signed webhook when conversion finishes. Idempotency keys and signed upload URLs for large files are built in.

How much does it cost?

The free plan includes 2 conversions a month with no credit card. Pro is $29/month with 50 conversions included ($0.75 each beyond that), and Scale is $149/month with 500 included ($0.40 beyond). Every plan uses the identical rendering engine.

Is my presentation content secure?

Uploads and converted packages live in private cloud storage, download links are time-limited signed URLs, and files are automatically deleted after the retention window (24 hours by default). Your decks are never used for anything except your conversion.

Your decks, everywhere.
