For exports, check exporting.applyStyleSheets and the export route: from Highcharts v12.3, PNG, JPEG, and SVG export locally by default, while local PDF needs additional modules and libraries. Typography and chart layout are separate concerns, so use Highcharts layout options to position elements rather than CSS margins or padding.
Choose how to style the chart
Highcharts supports styling through chart options and through CSS. Choose based on whether you want the chart’s appearance configured alongside its data, or managed through a stylesheet and theme.
Use chart options for targeted text styles
Set the text and its typography in the relevant Highcharts option. For example, a title can use title.text and title.style; axis labels have their own style, and legend items have corresponding styling options. Highcharts text style properties use JavaScript camel case, such as fontFamily, not CSS property spelling such as font-family. The official Design and style guide describes text and layout options.
Text options control text presentation. To place chart elements, use Highcharts layout controls—such as alignment, spacing, and positioning options appropriate to the element—instead of relying on general CSS margins or padding. This matters because Highcharts calculates the chart’s plot area and surrounding elements as part of its own layout.

Use styled mode for a CSS-led design
Set chart.styledMode: true to move presentation into CSS. In styled mode, Highcharts omits many presentational SVG attributes, including fills, strokes, and font styles, so your stylesheet supplies those values. Load the default highcharts.css and add overrides, or define a custom theme. The Highcharts CSS styling guide documents this approach and its chart classes.
A rule on .highcharts-root can provide inherited properties such as the font family; more specific Highcharts classes let you target particular chart elements or series. Prefer documented classes, and use version-specific stylesheet URLs in production so that the CSS and the Highcharts version used by your application stay aligned.
Configure custom text and CSS
The following example uses option-based title and axis-label typography, while enabling styled mode for the chart’s broader CSS design. Include the CSS and JavaScript assets for the same Highcharts version in your page; the paths below are illustrative local asset paths, not a claim about a particular release’s file structure.

},
series: [{

}]
});
</script>This deliberately demonstrates two styling routes in one chart. In a styled-mode chart, CSS is responsible for presentation; if you need a fully CSS-led theme, define typography and colors in CSS rather than assuming every option style will supply the final appearance. Conversely, for a chart that does not use styled mode, option-based text styles are the straightforward way to control title, axis, and legend text. Validate the combination against the Highcharts version you deploy.
Style titles, labels, and legend text
- Title and subtitle: define the displayed content in the title or subtitle text option. Their options also support text styling; inline spans can be used where part of a title needs different formatting.
- Axis labels: set label typography through the axis label’s
styleoption. For CSS-led styling, use the relevant Highcharts class in styled mode. - Legend items: use the legend’s text styling option for option-based typography, or the matching chart CSS class in styled mode.
When custom text contains markup-like spans, ensure the text and any styling are supported by the Highcharts text configuration you are using. Do not use arbitrary CSS layout rules as a substitute for chart options that control element placement.
Make sure custom CSS survives export
On-screen appearance and exported output are related, but they are not the same rendering context. Check exporting.applyStyleSheets when your chart depends on user-applied CSS. The API reference describes this setting as allowing CSS to be retained in export, and says it is enabled by default in styled mode. If an export looks different from the page, verify that the relevant styles are available to the export path and that layout is controlled by chart options where necessary.

Custom fonts are another common source of mismatch. Highcharts documents that, from v12.3, external fonts declared with CSS @font-face rules are included in exported images. Explicitly setting fontFamily in export options disables that automatic font inclusion. If the desired typeface disappears or falls back, check the deployed Highcharts version, how the font is loaded, and whether export options explicitly set a family.
Export as PNG, JPEG, SVG, or PDF
The Export module provides download and print controls for PDF, PNG, JPG, and SVG. The Export module overview documents a default export scale of 2: a chart displayed at 600×400 pixels produces a 1200×800 pixel image by default. This is output scaling, not a change to the chart’s CSS layout dimensions.

According to Highcharts’ client-side export guide, from v12.3.0 the export module handles PNG, JPEG, and SVG locally by default. Local export avoids sending the chart configuration to Highsoft’s server. Local PDF is different: it requires offline-exporting.js and supporting libraries. Older or unsupported browsers may fall back to the export server unless fallback is disabled, so check the supported-browser information for your actual audience before relying on offline export.

Use an export server when local export is not enough
Highcharts suggests considering client-side export first. If it does not meet your requirements, its current server setup documentation describes a Node.js export server that accepts chart configurations or SVGs with additional resources and uses Puppeteer to render PNG, JPG, PDF, or SVG. A self-hosted server can be relevant when browser support or a private rendering service is a requirement, but it also means operating that service.
If you use Highcharts’ public export server, review its terms and fair-use policy. Highcharts says requests must include Referer and User-Agent headers and that it may manage or restrict excessive usage. Do not assume an endpoint is an unlimited production rendering service.
Pick an export route by privacy and operational needs
| Route | Where rendering happens | Browser and format considerations | Operational trade-off |
|---|---|---|---|
| Client-side export | In the user’s browser for supported local exports; the client-side guide describes this as avoiding external transmission of chart configuration. | From v12.3, PNG, JPEG, and SVG are local by default. Local PDF needs offline-exporting.js and supporting libraries. Browser support varies; unsupported cases may fall back to the export server. |
Less server infrastructure for supported formats, but behavior depends on browser support and loaded modules. |
| Self-hosted export server | Your Node.js service using Puppeteer, as described in Highcharts’ server setup guide. | Can render PNG, JPG, PDF, or SVG from chart configuration or SVGs with additional resources. | You operate and maintain the rendering service; Highcharts positions this for requirements client-side export does not satisfy. |
| Highcharts public export server | Highcharts’ hosted export service. | Follow the service’s required request headers and fair-use terms. | Review the terms and account for the fact that chart configuration is sent to a server. |
Troubleshoot mismatched text and exports
- CSS has no effect: confirm
chart.styledModeis enabled, the expectedhighcharts.cssis loaded, and your selector matches the rendered Highcharts class. In styled mode, presentation is intentionally supplied by CSS. - Text looks styled but is misplaced: change Highcharts layout options for the title, legend, or axes rather than adding CSS margin or padding. Typography and placement solve different problems.
- Export loses a custom style: inspect
exporting.applyStyleSheetsand confirm the CSS applies in the export context. The option is documented as on by default in styled mode. - Export uses the wrong font: check that the font is loaded, that the export path supports its loading method, and whether an explicit export
fontFamilyprevents automatic inclusion of an@font-facefont. The documented automatic inclusion behavior applies from v12.3. - PDF export fails locally: add
offline-exporting.jsand its supporting libraries, or use an appropriate server route. PNG/JPEG/SVG local-export defaults do not mean local PDF has the same requirements. - Some users are redirected to a server: verify browser support and fallback settings. Highcharts documents server fallback for older or unsupported browsers unless fallback is disabled.
- Output dimensions are larger than the chart on screen: review export scaling. The documented default scale of 2 doubles the pixel dimensions of a 600×400 chart.
- Hosted export requests are refused or restricted: include the required
RefererandUser-Agentheaders and check the public server’s terms and fair-use guidance.
