The request came from a partner at a consultancy who had watched a colleague present a link-based deck in a basement meeting room with no signal. The deck was fine. The room was the problem.
Everything inlined
The HTML export contains the slides as markup, the fonts as base64, the images as data URIs and about eleven kilobytes of navigation script. No CDN, no analytics, no fetch calls. Open it from a USB stick on a machine that has never seen the internet and it presents.
If your presentation needs a network connection, you have two things that can fail instead of one.

PDF is excellent and free on every plan, but it cannot do build order, speaker notes or presenter view. The HTML export keeps those. It is the format we use internally for anything presented live.
Both sit alongside the .pptx, and none of them cost credits.
