The complete format guide: what deckshare opens, streams, and stores

Investors do not arrive with a tidy MIME-type checklist — they arrive with a folder. A Keynote deck from Monday, an MP4 product walkthrough from Tuesday, a ZIP of source exports from your CTO, and a CSV traction export someone forgot to convert.

deckshare.ai routes each upload intelligently: video through Deckshare streaming for adaptive HLS playback globally; documents, images, and audio through the Deckshare converter for in-room preview; archives stored in Deckshare storage for secure download when preview is unnecessary.

Video — Deckshare streaming

Adaptive streaming for diligence recordings, founder updates, and product demos. Formats we ingest include:

MP4 · MOV · M4V · MKV · WebM

Deckshare handles transcoding and global delivery; visitors receive signed playback tokens — no generic iframe embeds.

Archives — download-only

When preview is not the point — source trees, bundled exports, legacy diligence drops:

Stored securely; offered for download when your space policy allows.

Practical limits

Each file may be up to 2 GB. Storage is unlimited under our published fair-use terms — built for fundraising rounds, not cold-storage archives.

Why two pipelines?

Specialisation beats a single hammer. Adaptive video streaming is engineered for investor-grade playback at scale; the Deckshare converter excels at faithful document and media normalisation. deckshare orchestrates both from one upload surface so founders never think about routing tables.
