Wix Video, and the way around it

Embed video on Wix
without losing quality.

Wix Video transcodes every upload into an H.264 MP4, and its documented supported range stops at 1920 by 1080 pixels. A master exported above 1080p keeps its own resolution on a Wix page only when it plays from a host that streams the file as uploaded, through an Embed HTML element. Here is the exact menu path, the code to paste, and how to deal with Wix embeds not resizing with the page.

The short answer

Wix Video re-encodes every upload
and documents a 1080p top end.

Wix is direct about it: an uploaded video is automatically transcoded into an MPEG4 file containing the H.264 codec. The same article gives the supported range as 480x470 to 1920x1080 pixels. So the file on a Wix Video player is a Wix encode, and 1080p is the highest size Wix documents.

That is fine for plenty of sites. It is not fine for a cinematography reel, a grade test or a product film delivered above 1080p, where the point of the page is the image you finished. For those, the working route is to leave Wix Video out of the chain: host the master somewhere that streams the file as uploaded, and place its player on the page with Wix’s Embed HTML element.

Every upload is transcoded into an MPEG4 file with the H.264 codec.

The working route

Add an Embed HTML element
and paste one iframe.

The path below uses the names Wix gives in its own editor article. Wix only displays HTTPS code and URLs, and asks that embedded code be up to date and HTML5 compatible. A plain HTTPS iframe meets both.

Export a file a browser can play

Use a codec your viewers' browsers decode, such as H.264 or HEVC, and test on the devices your audience uses. A ProRes or camera RAW master is the right archive file and generally the wrong file for a web page.

Upload and copy the film's embed code

Upload the export (Up to 5 TB per file, within the storage left on your plan) and set the film to public, unlisted or embed-only. Copy its embed code, then use the Wix version below.

Add Embed HTML in the Wix Editor

Add Elements, then Embed Code, then Popular Embeds, then Embed HTML. Click Enter Code, paste under Add your code here, and click Apply. The optional What's in the embed? field is your alt text.

Size it, then check mobile

Drag the element to a 16:9 box, for example 960 by 540. Then open the mobile editor and check the element there before publishing, since Wix says embeds may display differently on mobile.

The code to paste into Embed HTML:

<iframe
  src="https://uncompressed.io/embed/VIDEO_ID?bg=000000"
  title="Your video title"
  frameborder="0"
  allow="autoplay; fullscreen; picture-in-picture; clipboard-write"
  allowfullscreen
  style="position:fixed;inset:0;width:100%;height:100%;border:0;"></iframe>

Replace VIDEO_ID with your film’s id and 000000 with your page’s background colour, as six hex digits without the hash. The style line is the change from a normal embed, and the next section explains it.

Why not Embed a site?

Wix’s other option, Embed a site, takes a web address (Enter Website Address, then What’s the website address?). It takes an address only. Embed HTML lets you set the iframe’s own attributes, including fullscreen permission and the style that makes the player fill the box. Wix also notes that some sites refuse to be embedded because of their security policies; if a URL shows nothing, that is the usual reason.

The resize problem

The Wix box does not resize,
so make the player fill it.

Wix says the HTML and URL elements in its editor are iFrames, and that the embedded content won’t be responsive, even if it is originally. A player that scales perfectly on its own page sits inside a box whose size you set by hand.

The usual embed code sizes the iframe from its width and an aspect ratio. Inside a Wix element that works against you: the box has a fixed size, and the iframe does not know it. The code above does the opposite. position:fixed;inset:0 with 100% width and height pins the player to the edges of the Wix box, whatever size you drag it to. The bg parameter sets the fill of the player’s frame, so set it to your page colour and any space the film does not cover blends into the page.

That leaves one manual step: the box itself. Set it to a 16:9 size in the desktop editor, then look at it in the mobile editor. Wix’s mobile article says embeds may be displayed differently on mobile and that certain iFrames are designed for specific screen sizes, so check the mobile layout before you publish rather than after a client mentions it. After publishing, test autoplay and fullscreen on the live site too, because the player now runs inside Wix’s own frame.

Per-placement settings

Eight parameters
on the embed URL.

Settings saved on the film apply first, and parameters added to the src override them for that one placement. For a silent loop at the top of a Wix page, for example: ?autoplay=1&loop=1&controls=none&bg=000000.

autoplay=1

Starts playback on its own and forces the player muted.

muted=1

Starts the player silent without starting playback.

loop=1

Repeats the film when it reaches the end.

title=1 or title=0

Shows or hides the title chip over the frame.

playbtn=0

Hides the large play button in the centre.

accent=RRGGBB

Six hex digits, no hash. Sets the player's accent colour.

controls=hover or none

hover floats the controls over the film on mouse-over. none removes controls, click-to-pause and the play button.

bg=transparent or RRGGBB

The fill around the film. Transparent by default.

What the embed will not show

Password-protected, private and vaulted films, and films still uploading, show a This video is unavailable card instead of playing. An archived film must be restored before it can be streamed or embedded. The player itself carries no platform logo; the only logo on it is your own, if you turn that on.

Not covered in theWix articles cited

Wix figures from the Wix Help Center, fetched 16 September 2026. Wix does not state what it does with a file above 1920x1080, and this table does not guess. Browser playback uses your uploaded export without another platform re-encode. Codec, device and connection requirements still apply.

Stay with Wix Video when your deliverable is already 1080p and a fresh H.264 encode is acceptable, when your visitors are mostly on phone data and a high-bitrate master would keep them waiting, or when you want the video to live in Wix’s own library with nothing to paste. Those are good reasons, and an embed adds a step you then own.

Embed when the image is the product: a reel judged frame by frame, a colour test, a film delivered above 1080p. High bitrate is not free to watch, so test the published page on an ordinary laptop and phone before you decide the embed is the better experience for your audience.

Questions

Frequently asked

Does Wix compress uploaded videos?

Wix states that uploaded videos are automatically transcoded into MPEG4 containing the H.264 codec. Whatever codec you exported, the file your visitor plays on a Wix Video player is a Wix-made H.264 MP4, not your original.

Can Wix Video play 4K?

Wix's supported-files article describes a supported range from 480x470 to 1920x1080 pixels. It does not say what happens to a file above that range, so this page does not guess. If the resolution of your master matters, embed it from a host that streams the file as uploaded.

Which Wix plan do I need for Embed HTML?

Wix's embed article names no plan requirement for Embed HTML or Embed a site. The requirement Wix does state, a Premium plan, a connected domain and no ads, applies to the Custom Element, which this workflow does not use. Check your own site before you rely on it.

Why is my embedded video cut off or tiny on mobile?

Wix says its HTML and URL elements are iframes and that embedded content won't be responsive, even if it is originally. Its mobile article adds that embeds may display differently on mobile. Make the player fill the element, as in the code on this page, then check the element in the mobile editor.

Will a password-protected film play in the Wix embed?

No. A password-protected, private or vaulted film shows a This video is unavailable card inside any embed. Set the film to public, unlisted or embed-only before you paste the code.

Put the export you graded on the page

Start free with 5 GB and one film at a time, upload a browser-playable export, and paste one iframe into a Wix Embed HTML element. Paid plans start at 100 GB of hot storage on Lite.
