Decklit FAQ – Security, Engagement & Green Streaming

Decklit is the platform built for everything that happens after you create a deck. Share securely without giving away your files, present live with native WebRTC streaming, keep your audience engaged with real-time Q&A, and capture insights that last long after the session ends.

Most professionals navigate multiple tools just to share, present and follow up on one deck. Decklit replaces all of them, with fewer tools, less spend and more efficiency in one place. The only platform engineered with dual view, a proprietary presentation experience where your deck, your screen share and your participants coexist on one screen simultaneously. No switching, no lost context, no divided attention. Audiences stay engaged, presenters stay in control, and with less hardware strain than traditional conferencing setups, the whole experience is more energy efficient by design.

One platform, one link, one place where every presentation lives from the moment it leaves your hands to the final piece of audience feedback.

Yes. Open the three-dot menu on your deck and select Edit. You can then either edit the current version in the Decklit editor, or upload a completely new file, PPTX or PDF, as a new version of the same deck. You can also do this from the versions page, using Edit or Upload new version.

The link stays the same, so anyone you've already shared it with will see the updated deck without needing a new link.

When you upload a new file, you can choose whether it becomes the current version straight away. Making a version current permanently clears the questions and notes on the deck, and they can't be restored. If you'd like to keep them for now, upload the new file without making it current. It will be saved under Other versions until you're ready.

Every version is kept. You can view them all under See all versions and set any of them as current at any time, bearing in mind that doing so also clears the questions and notes.

You decide. When you upload your deck, you can choose whether to make it available to your audience after the presentation. Your deck remains available for up to 30 days after the live session ends, and you can remove it at any time before then. If you choose to share your deck, you can make it available for a limited time after the presentation (24h, 48h, or 72h) or for the entire period during which the deck is available on the platform.

Decklit is built for sharing professional presentations, particularly with external audiences. It's well suited for client presentations, sales pitches, webinars, training sessions and white-labelled decks, offering a secure, browser-native environment that protects your content and enhances engagement. It can also be used for internal presentations where privacy and controlled access are important. Uploads are supported in PDF and PPTX, with PPTX recommended when your deck includes GIFs or videos.

Yes. Decklit provides a native WebRTC presentation experience designed specifically around slides, not generic video calls. Its key differentiator is the ability to present your deck and share an additional screen at the same time, keeping your slides persistent while showing demos, documents, or other content when needed (available on paid plans).

Decklit can be used on its own for presentation-focused sessions, or alongside tools like Zoom, Google Meet, or Microsoft Teams. When the presentation is delivered directly through the deck, Decklit helps reduce unnecessary data usage compared to traditional screen sharing, making sessions lighter and more sustainable while giving you greater control over your content and interactions. If screen sharing is used extensively within external meeting tools, performance will depend on those platforms.

Yes. When you upload a PPTX, Decklit's engine extracts embedded GIFs and videos and places them back exactly where they sat on the slide. GIFs play and loop automatically, and videos play at full quality on each viewer's own device, including phones, rather than through a compressed screen share.

For the most reliable playback, especially with longer or high resolution videos, we recommend adding them natively through the Decklit editor after uploading your deck. Media added this way is handled directly by Decklit and gives you full control over how it plays.

Note that PDF files cannot carry media. If your deck includes GIFs or videos, upload the PPTX rather than a PDF export.

Decklit converts uploaded slides into images to ensure stability, privacy and optimal performance during live sessions. GIFs and videos embedded in a PPTX are the exception, and are extracted and played back in place. See "Are GIFs and videos in my PowerPoint supported?" for details.

With the built-in Editor, you can reorder or remove slides, add structured transitions, and embed videos directly into your deck. Because media is handled natively within Decklit, playback is more stable and consistent than traditional screen sharing or external embeds.

Element-level animations, such as objects appearing one by one within a slide, aren't preserved automatically. For animated sequences, we recommend splitting them into consecutive slides before uploading for the best visual result.

Pressing "End Session" will immediately end the live streaming for everyone. Once stopped, the session cannot be resumed, and you’ll need to upload the deck again to create a new session and generate a new QR code.

If your content hasn’t changed, you can use the Duplicate feature to quickly create a new session without re-uploading the deck. You can also update the title and session time before starting the new live stream.

For the best experience with text and layout, we recommend uploading your file as a PDF. This preserves fonts, layout and design exactly as intended. Export directly from PowerPoint via File → Export → PDF, and always check the PDF looks correct before importing. If something looks off there, fix it in your original tool first. If your deck includes GIFs or videos, upload the PPTX instead, since a PDF turns every slide into a still image.

If your presentation uses custom or non-standard fonts, make sure they are embedded before exporting. On Windows, go to File → Options → Save, check "Embed fonts in the file" and select "Embed all characters". On Mac, go to PowerPoint → Preferences → Save and do the same under Font Embedding. Some fonts are restricted by their creator and cannot be embedded. If that happens, replace them with a standard font before exporting.

When uploading a PPTX, some font weights such as semibold, medium or light may not display as intended and can appear as regular or bold instead. If that happens, export the deck as a PDF, which preserves every weight exactly. If you need to keep the PPTX, for example because it contains GIFs or videos, switch those text styles to bold in PowerPoint before uploading.

If you work in Google Slides, export as PDF rather than PPTX. Google Slides embeds fonts automatically on PDF export, whereas its PPTX export can shift fonts, spacing and layout when opened outside Google. The same applies to round trips. If a deck was originally made in PowerPoint, avoid uploading a version that has been imported into Google Slides and exported back to PPTX, as each conversion can move margins and spacing. Upload the original PowerPoint file instead.

Decks created in AI or design tools such as Canva, Gamma, Beautiful.ai or Claude Design are best exported as PDF rather than PPTX. Their PPTX exports go through a conversion layer that can lose fidelity or carry hidden formatting, so the file may already differ from what you designed before it reaches Decklit. Their PDF export preserves the design as intended, and Decklit renders it faithfully. If your deck includes GIFs or videos and you need the PPTX, check the slides after importing and swap any that shifted for an image via the editor. Need to fix just one slide after importing? Go back to your original file, correct the slide, and export it as a PNG or JPEG at 2560x1440. Upload it to your Decklit gallery and swap it in via the editor — no need to re-upload the full deck.

Steps may vary depending on your version of PowerPoint. Always refer to the official Microsoft support documentation for the most up to date instructions. If you need support, you can always contact us at [email protected].

Decklit includes built-in WebRTC video and audio to support real-time interaction during presentations. For optimal performance, we recommend that participants turn off their cameras when they don't need to be seen, as this significantly helps maintain call stability and quality.

Decklit's unique architecture does not require screen sharing to present slides. Slides are delivered directly to participants' devices, which significantly reduces bandwidth usage compared to traditional screen-sharing meetings.

For audiences where many participants have video enabled, turning off cameras where possible and switching to audio-only for attendees who don't need to be seen ensures a smooth experience for everyone. Decklit can also be used alongside traditional WebRTC meeting tools, which complement the presentation experience while Decklit continues to handle slide delivery and engagement.

Each deck thumbnail gives you a visual indication of its current state.

Before a live session, the View Deck button appears in purple and no status label is shown as the deck has not been presented yet.

Once a live session has taken place, the View Deck button turns blue and a status label appears to let you know the deck's current availability:

Active — the deck is live and accessible to viewers
Expiring soon — viewer access will expire in less than 24 hours
Expired — the deck is no longer accessible to viewers, though you as the presenter retain access for up to 30 days from when the live session ended

To keep Decklit fast and resource-efficient, we automatically close sessions that stay inactive for too long. If a deck is left unviewed for 1 hour and 10 minutes, you'll be returned to the dashboard, even if a live session is in progress.

This is a deliberate safeguard. Keeping a session open continuously uses streaming and processing resources, so when no one is actively viewing the deck, we close it rather than let an idle session run indefinitely. It protects both the platform's performance and your own consumption.

What this means in practice::

If you're a viewer: if you're returned to the dashboard, you can simply rejoin the live call if one is still running. Nothing is lost.
If you're the presenter: if you step away and the deck stays inactive past the 1 hour 10 minute limit, the session ends for everyone and the call closes. If you're planning a long pause or break, keep this in mind, the session won't stay open in the background while idle.

Tip: for long sessions, keeping the deck in active view prevents the timeout. If you need an extended break, let your audience know they may need to rejoin once you resume.
