Why SlideKiln
All 187 preset shapes, custom geometry, text cascades, tables, effects and fills — parsed straight from OOXML with no conversion middlemen.
The full timing engine ships with every package: entrances, emphasis, motion paths and Morph transitions play back exactly as authored.
Server-side text layout with true font metrics and an embedded font service, so line breaks land where PowerPoint put them.
Native chart rendering and SmartArt support, including embedded video and audio with transcode controls.
REST API with idempotency keys, signed upload URLs for big files, HMAC-signed webhooks and correlation ids.
Organizations with roles and invites, per-key usage attribution, and usage-based billing that scales with you.
Drag a .pptx into the converter, watch the job progress live, and download the package when it lands.
Create an API key, POST the file (or a source URL), poll the status endpoint or receive a signed webhook.
The output is a self-contained bundle of HTML, SVG, CSS and JS — a static folder any CDN can serve.

Flip on hosting when you convert — or mark any recent conversion as hosted — and we serve the deck live at a stable public URL. Drop it into any page with an <iframe>. No zip to unpack, no server to run. Prefer to self-host? Every conversion still downloads as a self-contained package you can put on your own CDN.

FAQ
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.
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.
Yes. Turn on hosting when you convert (or mark any recent conversion as hosted from the dashboard) and we serve the deck live at a stable public URL — paste it into any page with an iframe, no zip to unpack and no server to run. Each plan includes a number of hosted presentations (2 on Free, 15 on Pro, 50 on Scale); unhosting one frees a slot. You can still download every conversion and self-host it instead.
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.
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.
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.
The free plan includes 2 conversions a month with no credit card. Pro is $29/month with 35 conversions included ($1.00 each beyond that), and Scale is $149/month with 350 included ($0.55 beyond). Every plan uses the identical rendering engine.
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) — unless you choose to host a deck, in which case that deck stays live at its public embed URL until you unhost it. Your decks are never used for anything except your conversion.
