“Export HTML to SVG” can mean either placing HTML inside an SVG’s <foreignObject> or converting supported page content into SVG elements. Use <foreignObject> when a compatible browser is the target and preserving HTML layout matters; use an SVG-native renderer or redraw the design when it must remain visible and editable in vector tools. Neither route guarantees that every browser, editor, or converter will display the same result.
Choose the export method for the file’s destination
Start by identifying where the SVG will be opened and what you need to edit. The extension alone does not tell you whether the file contains native vector shapes, raster images, or an HTML fragment wrapped inside SVG.
| Method | What the SVG contains | Best fit | Main limitation |
|---|---|---|---|
<foreignObject> wrapper |
HTML content embedded inside an SVG element | Showing a web-rendered component in a compatible browser | Some standalone SVG viewers and vector applications may omit the HTML |
| DOM-to-SVG renderer | SVG-native output for supported content; some images or canvas may remain raster | Vector-oriented output when the renderer supports the page’s elements and styles | Coverage is tool-specific; unsupported CSS or content may render incorrectly |
| Application-specific export or redraw | Depends on the editor’s export implementation; redrawing can produce native SVG | Graphics that must survive a particular downstream tool | HTML-backed editor content may still export as <foreignObject> |
MDN describes <foreignObject> as a way to include elements from a different XML namespace, most commonly XHTML in browser use. Its width and height define the embedded content’s layout area. MDN cautions: “A standalone SVG viewer is unlikely to be able to render HTML or MathML.” See MDN’s foreignObject reference and Other content in SVG.
Option 1: wrap HTML in SVG with foreignObject
This is the most direct way to preserve HTML rendering in an SVG container. It does not convert the HTML into paths or native SVG text: the browser still has to interpret and paint the embedded markup.
#1 Best Overall
Create a minimal wrapper
For a simple, self-contained example, save the following as card.svg and open it in a browser that supports the embedded XHTML:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xhtml="http://www.w3.org/1999/xhtml" width="640" height="360" viewBox="0 0 640 360">
<foreignObject x="0" y="0" width="640" height="360">
<xhtml:div style="box-sizing:border-box;width:640px;height:360px;padding:32px;background:#f3f6fb;font:16px Arial,sans-serif;color:#182230">
<xhtml:h1 style="margin:0 0 12px;font-size:28px">Exported component</xhtml:h1>
<xhtml:p style="margin:0">This content is HTML inside SVG, not native SVG text.</xhtml:p>
</xhtml:div>
</foreignObject>
</svg>The explicit XHTML namespace helps identify the embedded content. Set the SVG’s width and height and the <foreignObject> dimensions to the layout area you intend to capture. Inline critical styles for a portable example; external stylesheets, script-generated layout, relative URLs, and web fonts can complicate rendering when the file is moved or opened outside the original page.
Use a browser-side converter for an existing fragment
A browser-based converter can accept an HTML fragment, place it inside <foreignObject>, inline styles, serialize the SVG, and offer a download. The operator of convertsvg.org says processing happens locally in the browser, without uploading the file, and that it inlines critical styles from same-origin stylesheets. The operator also says styles from external CDNs need to be inlined manually. Those are the tool operator’s statements, not an independent privacy or compatibility audit.
Before using any converter, check whether the result is a wrapper or native SVG. Open the downloaded file as text: a <foreignObject> element indicates embedded HTML. Then open it in the actual browser or app where you plan to use it.
Option 2: render supported DOM content into SVG elements
If HTML inside <foreignObject> is unsuitable, a DOM-to-SVG renderer may map supported content into SVG-native output. For example, the @tooooools/html-to-svg project documents selecting an element, constructing a renderer, preloading declared fonts, rendering the element, and serializing or downloading the SVG. Its project documentation says text is outlined using Opentype.js, and that its documented path requires explicit font declarations because it does not yet load local fonts.
Typical package workflow
Install and use the package according to its current README and examples; its API can change, so do not assume an unverified snippet from an older release will run unchanged. Conceptually, the documented workflow is:
- Select the DOM element you want to export.
- Declare and preload the fonts the renderer should use.
- Construct the renderer and render the selected element.
- Serialize or download the returned SVG.
- Inspect the output in the destination application, especially text, images, and unsupported styling.
The project lists renderers for div backgrounds and border radius, text, <img>, canvas, and inline SVG. Its documentation says canvas is embedded as PNG in the SVG; inline SVG is also described as rasterized into an SVG image when that option is used. Therefore, a file with an .svg extension may contain raster content rather than editable vector paths for every part.
Check feature coverage before relying on it
A DOM renderer does not automatically support all browser CSS and HTML. The project documents specific renderers and a roadmap of unsupported CSS features. Validate the elements and styles you actually use instead of assuming a whole web page will reproduce perfectly.
Recommended Free Tools
- Check text for missing glyphs, fallback fonts, changed line breaks, and unexpected outlines.
- Confirm images have loaded and that their URLs remain available or their content is embedded as expected.
- Inspect canvas output separately; it may be raster data inside the SVG.
- Compare backgrounds, borders, rounded corners, layout, and effects against the browser rendering.
Option 3: export from the application that owns the content
If HTML is only the rendering implementation inside a graph or editor, use that product’s export API when available. Then test the exported file in its actual destination. The export API may produce a wrapper rather than vectorizing the HTML.
JointJS documents SVG export and warns that its HTMLBox/HTMLHost content is placed in <foreignObject>, which may disappear in vector tools such as Illustrator or Inkscape and in some SVG-to-PDF or raster converters. It recommends native SVG rendering when output must work in those tools. See JointJS SVG export documentation.
Compare fidelity, editability, fonts, and compatibility
There is no single “best” conversion independent of the destination. The documented features and limitations of the methods differ; the available sources do not establish an independent head-to-head benchmark.
| Question | foreignObject |
DOM-to-SVG renderer |
|---|---|---|
| Does it preserve browser-style HTML layout? | It embeds HTML for a browser to lay out and paint | Only to the extent the renderer supports the relevant DOM and CSS |
| Is the content native/editable vector artwork? | No; the HTML remains embedded content | Potentially for supported elements and text; inspect rasterized content |
| What about fonts? | Rendering depends on the viewer’s ability to resolve the font and styles | The cited package requires declared fonts for its documented Opentype.js workflow |
| What about images and canvas? | They remain HTML content rendered by the viewer | The cited package documents canvas as PNG in SVG and an inline-SVG option that rasterizes into an SVG image |
| Will it work in standalone SVG viewers and design apps? | Not reliably; standalone viewers may not render embedded HTML | Depends on generated SVG features and the target application |
| Is local processing established? | Depends on the tool; convertsvg.org’s operator says its browser tool processes locally | Depends on the implementation and how it handles assets |
Troubleshoot blank or incorrect exports
The SVG looks blank in Illustrator, Inkscape, or a converter
Inspect the file for <foreignObject>. If present, the target may not render the embedded HTML. Use a renderer that produces native SVG for the content you need, redraw it with native SVG, or choose a compatible browser as the viewer. An SVG file is not guaranteed to display identically in every application.
Fonts or line breaks changed
For a DOM-to-SVG workflow, declare and preload fonts as required by the renderer. Verify that the intended font is available to the rendering workflow; a fallback can alter glyph shapes, widths, and wrapping. For a foreignObject wrapper, remember that the viewer must resolve the CSS and font resources used by the embedded HTML.
Styles or layout disappeared
Make critical styles self-contained or inline them. Check that the wrapper dimensions are large enough, and confirm external stylesheet URLs are accessible from the context in which the SVG is opened. For convertsvg.org specifically, its operator says external CDN styles must be inlined manually.
Images or canvas are not editable
Check the renderer’s output and documentation. The cited package embeds canvas as PNG and describes rasterization for its inline-SVG option. If those areas must be individually editable as vectors, recreate them as native SVG shapes or use a workflow that explicitly supports vector output for those elements.
The result differs from the source page
Reduce the test to one representative element and compare it with the original browser view. Verify image loading, font selection, supported CSS, and any script-dependent layout. A renderer’s documented element support is not a promise that arbitrary pages will match pixel for pixel.

Final checks before you depend on the file
- Open the SVG in the exact application or viewer that will consume it.
- Determine whether it contains
<foreignObject>, native SVG elements, embedded raster images, or a mixture. - Check font appearance, image loading, clipping, dimensions, and any content known to be rasterized.
- If editability matters, select and inspect the output elements in the target editor rather than judging only by appearance.
Frequently Asked Questions
Does exporting HTML to SVG make the whole page vector?
No. A foreignObject wrapper keeps the HTML embedded, while DOM renderers may create vector elements for supported content but can leave images or canvas as raster.
Why does an SVG with HTML look blank outside a browser?
The file may rely on foreignObject, which some standalone SVG viewers, design applications, or converters do not render.
