Embed codes: iframe, script loader and parameters
Videokr gives you two embed codes for the same video. An iframe pointing at /e/VIDEO_ID works anywhere HTML is allowed, and a one-line script loader (embed.js with data-video) inserts a responsive iframe for you and reports its own height for playlists. Both accept autoplay, muted, start and token parameters.
Iframe embed
<iframe src="https://videokr.com/e/vid_abc123" title="Product tour"
style="width:100%;aspect-ratio:16/9;border:0"
allow="autoplay; fullscreen; picture-in-picture; encrypted-media"
loading="lazy"></iframe>Use the iframe when the host page restricts scripts (many CMS and email-builder contexts do). Keep aspect-ratio on the iframe rather than a fixed height so it stays responsive, and keep loading="lazy" so an embed below the fold costs the page nothing until it is scrolled into view.
Script loader
<script src="https://videokr.com/embed.js" data-video="vid_abc123" async></script>The loader replaces itself with a correctly-shaped, responsive box, sets the iframe allow list and loading="lazy" for you, and — for a playlist — listens for the player's own height message so the queue is never clipped.
Attributes:
| Attribute | Purpose |
|---|---|
data-video | Video id or slug. |
data-playlist | Playlist id or slug (instead of data-video). |
data-target | CSS selector to mount into, instead of in place. |
data-width | Any CSS width; defaults to 100%. |
data-ratio | 16/9 for a video, 16/11 default for a playlist. |
data-autoplay | Start playback when allowed by the browser. |
data-muted | Required alongside autoplay in most browsers. |
data-start | Start at N seconds. |
data-token | Access token for a password-protected video. |
URL parameters
The same options work on the iframe URL: /e/vid_abc123?autoplay=1&muted=1&start=30. A playlist embed uses /ep/PLAYLIST.
Autoplay only starts without a click when the video is muted — that is a browser rule, not a Videokr one. An autoplaying muted loop with a visible unmute control converts better than a forced-sound autoplay that the browser blocks anyway.
Multiple embeds on one page
Both forms are safe to repeat. Each embed is a separate player in its own iframe, so styles cannot leak between your page and the player either way.
Deep links and public pages
Every video also has a shareable public page at /v/slug with ?t=90 deep linking into a moment, and a Markdown twin at /v/slug.md for assistants. See SEO video pages.
Access-controlled embeds
A domain-locked video only plays on the hostnames you list — wildcards allowed — and refuses anywhere else, so a copied embed code is worthless on someone else's site. A password-protected video needs a token, which the public page issues after the password is entered.
Frequently asked questions
Which embed should I use?
The script loader, unless your CMS strips scripts — it handles sizing and lazy loading for you. Use the plain iframe where scripts are not allowed.
Does the embed work outside WordPress?
Yes. Both embeds are plain HTML and work on any site or framework. The WordPress plugin is a convenience, not a requirement.
