If a Vuetify icon appears in the browser but disappears from an image made with html-to-image, first identify how the icon is rendered: as a font glyph or as SVG. Font icons need their CSS and font files available to the capture process; SVG icons need their markup, paths, dimensions, and styles present in the captured element. Then capture only after Vue has rendered the target and its required assets are ready. There is no universal one-line fix: the correct configuration depends on your Vuetify major version, icon library, and capture timing.
Why Vuetify icons can disappear from an html-to-image export
html-to-image does not take a screenshot of the browser window as-is. Its capture path clones and serializes a DOM node through an SVG stage, embeds web fonts and images, and then renders that SVG to a canvas for raster output. A visible browser icon can therefore be missing if its font, CSS, SVG markup, or styling does not make it through that process.
That distinction matters because an icon that is absent from the live page has a different cause from an icon that appears on the page but vanishes from the exported image. In the first case, investigate Vuetify registration, the icon name, and the library assets. In the second, investigate whether the capture target contains the icon and whether the relevant styles and assets are available when capture runs.
Identify whether the icon is a font glyph or SVG
Font-based icons
A font icon is usually represented by an element with an icon class and text-like glyph content. Its appearance depends on the matching stylesheet and font file. In developer tools, check that the expected class or content is present, that the intended font face is applied, and that the font has loaded. If the browser is showing a fallback glyph or an empty character, fix that before investigating image export.

For Vuetify 2, the official icon guide documents icon-font presets, including MDI. Its MDI font example imports @mdi/font/css/materialdesignicons.css. The selected icon library must be included in the project and match the Vuetify preset. Importing a different library’s CSS, or configuring one preset while rendering another library’s icon names, can leave icons missing even in the normal page.
SVG icons
An SVG-based icon should leave visible SVG markup in the target subtree: an <svg> element with a path or other drawable content. If the SVG exists but is invisible, check its dimensions, fill, and inherited color. Vuetify 2’s guide documents its mdiSvg approach using paths imported from @mdi/js; for custom SVG icons it notes that fill: currentColor allows the icon to inherit color and scale as intended.
When possible, inline SVG or path-based output is a useful choice for an export target because the drawable content is part of the captured DOM rather than depending on a separately loaded icon font. It still needs appropriate dimensions and styles; SVG markup alone does not guarantee a visible result.

Use Vuetify configuration that matches your major version
The cited Vuetify icon guide applies to Vuetify 2, not every Vuetify project. It identifies Vuetify 2 as end of life and shows v2.7.2 as its latest release. Use its mdiSvg, @mdi/js, or icon-font examples only when your project actually uses Vuetify 2. A Vuetify 3 project needs the documentation and configuration for its own major version; do not paste a Vuetify 2 preset into it and assume the settings are interchangeable.

Before changing the capture code, verify these items in the running application:
- The icon component is registered and is using the icon name expected by the configured library.
- The configured preset and imported CSS, font, or SVG path source refer to the same icon library.
- The icon appears inside the exact element passed to the capture function, rather than elsewhere on the page.
- The computed styles give it visible color and nonzero size.
Capture after Vue and the icon assets are ready
Call the capture function after Vue has rendered or updated the target. For font-based icons, wait for the document’s fonts to finish loading as well. This is a timing safeguard, not a universal diagnosis: if the icon is misconfigured or its library is absent, waiting will not fix it.

A minimal pattern for a mounted Vue component is:
import { nextTick } from 'vue'
import { toPng } from 'html-to-image'
async function exportElement(element) {
await nextTick()
if (document.fonts?.ready) {
await document.fonts.ready
}
return toPng(element)
}Pass the actual DOM element you want to export to exportElement. In a component, obtain it from a template ref after mount and invoke the function in response to an export action. If the element is conditionally rendered, wait until it exists before calling the function. The font wait is particularly relevant to font glyphs; it does not substitute for confirming SVG paths or other assets are present.
Inspect the intermediate SVG to locate the failure
Use toSvg on the same target before debugging the final PNG. The library’s capture sequence calls toSvg before producing a canvas image, so the intermediate representation helps divide the problem:
import { toSvg, toPng } from 'html-to-image'
async function inspectCapture(element) {
const svgDataUrl = await toSvg(element)
console.log(svgDataUrl)
const pngDataUrl = await toPng(element)
return { svgDataUrl, pngDataUrl }
}Open the logged SVG data URL in a browser or inspect its decoded contents. If the icon is already missing there, focus on the cloned target, CSS, font embedding, or external assets. If the icon is visible in the SVG but missing in the PNG, investigate the later SVG-to-canvas rendering stage and the browser environment used for export.

For a font icon, look for the relevant font styling and whether the font data is represented in the SVG. For an SVG icon, confirm the copied markup still contains its paths and that its fill and dimensions are visible. This check prevents changing Vuetify configuration when the icon is already present in the intermediate output—or chasing canvas behavior when the icon never entered the serialized target.
Troubleshoot missing icons by symptom
The icon is missing on the live page
- Check the icon name and preset. Confirm the name is valid for the selected library and the project is configured to use that library.
- Check library assets. For Vuetify 2 font icons, ensure the matching CSS and font package are included. For its SVG approach, ensure the path import and SVG icon configuration agree.
- Check the console and network panel. A missing stylesheet or font request can explain a blank or fallback glyph before image export starts.
The icon appears on the page but not in the export
- Check the capture boundary. Inspect the element passed to
toPngortoSvg; the icon must be a descendant of that node. - Wait for rendering and fonts. Allow Vue’s update cycle to complete, then wait for
document.fonts.readywhere font glyphs are used. - Inspect the intermediate SVG. If the icon is absent there, investigate clone-time styling and assets. If it is present there, investigate rasterization.
- Check SVG styling. Confirm paths have visible fill, the SVG has usable dimensions, and inherited styles such as
currentColorresolve to a visible color.
Only Font Awesome through Vuetify fails
A historical Vuetify issue describes a Font Awesome SVG integration failure in Vuetify 2.3.17, Vue 2.6.11, and Chrome 86 on Windows 10. The reporter found Font Awesome worked outside the Vuetify icon component but not through it; the issue is marked expected/wontfix. This is an example of an icon-integration problem separate from html-to-image, not evidence of a current general incompatibility between the capture library and Vuetify icons. First verify the icon independently in the live page.
Or skip the browser setup
If your Vue page is publicly reachable and you need a screenshot of the page rather than an arbitrary in-memory DOM node, ScreenshotNeo can capture its URL with one GET request. It is a website screenshot API, so it is not a drop-in replacement for exporting a single selected element from a local Vue application. See the ScreenshotNeo API documentation for request options.

FAQ
Should I use font icons or SVG for an exported Vuetify component?
Either can work. SVG puts drawable paths in the target markup; font icons depend on CSS and font availability during serialization. Choose the representation supported by your Vuetify version and verify it in the intermediate SVG.
Does a successful toSvg result guarantee a successful PNG?
No. It shows whether the icon survived the DOM-to-SVG stage. A later canvas rendering issue can still affect the raster output.
Can ScreenshotNeo export one Vue component from an unsaved local page?
No. ScreenshotNeo captures a URL. It is suited to capturing a reachable page, not selecting an arbitrary node from a local application’s in-memory DOM.
