Use dom-to-image to render a DOM node into an image, then download or display the result. For a long page, select the document element and pass its scroll width and height as render dimensions. This is a practical starting point, not a guarantee: very large pages, missing cross-origin images, and browser rendering limits can produce incomplete output, so inspect the result in the browser you plan to support.
What dom-to-image captures—and what “full-page” means
dom-to-image is a JavaScript library that renders a selected DOM node to SVG, PNG, or JPEG. Its methods return promises, so you can wait for the generated image before displaying or downloading it.
This is DOM rendering, not a physical screenshot of the browser window. The output is derived from the node and the resources and styles the library can render. A page-sized image therefore depends on selecting a node that contains the page content and requesting dimensions that cover that content. It does not establish a universal maximum capture size or guarantee a pixel-perfect match to what you see on screen.
For the whole document, document.documentElement is a reasonable starting selection. Some sites place relevant content or scrolling on a different element, such as document.body or an application container. Check which element actually contains the content and has the expected scroll dimensions before capturing.

Install the library and choose a node
Install from npm
In a project that uses npm, install the package:
npm install dom-to-imageIn a bundled application, import the package and select the node you want to render. The repository also documents including a browser script that exposes a global domtoimage object; use the method names below with whichever setup you choose.
import domtoimage from 'dom-to-image';
const node = document.documentElement;If your build setup does not accept a default import, follow the module format supported by your project and the package. The important part is that domtoimage refers to the library object and node is the DOM element to capture.
Capture the full document to a PNG file
This example requests the document element’s scroll dimensions, renders a PNG, and triggers a browser download:
const node = document.documentElement;
domtoimage.toPng(node, {
width: node.scrollWidth,
height: node.scrollHeight,
})
.then((dataUrl) => {
const link = document.createElement('a');
link.download = 'page.png';
link.href = dataUrl;
link.click();
})
.catch((error) => {
console.error('Could not render the page', error);
});The width and height options are applied to the node before rendering. Reading scrollWidth and scrollHeight is useful for estimating the content extent, but this adaptation is not a project-published guarantee that every long page will render completely. Confirm the resulting file’s dimensions and inspect the bottom and edges for clipping or blank areas.

Capture a particular region instead
To capture a component rather than the whole page, pass that element as the node. For example:
const node = document.querySelector('#report');
if (!node) {
throw new Error('Could not find #report');
}
domtoimage.toPng(node)
.then((dataUrl) => {
const image = new Image();
image.src = dataUrl;
document.body.appendChild(image);
})
.catch((error) => console.error('Could not render #report', error));Use a selector that uniquely identifies the intended element. If you need a long component’s full contents, measure that element’s own scroll dimensions rather than assuming the document’s dimensions apply.
Choose the output format and rendering options
The library provides several output methods. Pick the format according to how the image will be used:
| Method | Result | Useful when |
|---|---|---|
toPng(node, options) |
PNG data URL | You want a lossless raster image that can be shown in an <img> or downloaded. |
toJpeg(node, options) |
JPEG data URL | You prefer a compressed photographic image and do not need transparency. |
toBlob(node, options) |
Blob | You want a binary image object, for example to save or process it without first handling a data URL. |
toSvg(node, options) |
SVG data URL | You want the library’s SVG output rather than a raster format. |
toPixelData(node, options) |
Pixel data | You need pixel values for further processing rather than a ready-to-download image. |
These methods are asynchronous. Handle their returned promises with .then() and .catch(), or use async/await inside an error-handling block.

Set a background, quality, or temporary style
bgcolorsets the background color for the rendered image. Set it when a transparent or unspecified background is not suitable for the destination.qualitycontrols JPEG image quality. It applies to JPEG output; it is not a way to increase the rendered dimensions.styleapplies style properties to the node before rendering. This can help adjust the captured node’s appearance for the image.filterexcludes a node and its children from rendering. Use it when a subtree should not appear in the result.imagePlaceholdersupplies fallback content if fetching an image fails. It can prevent a failed image resource from leaving an unintended gap, but it does not make the original resource available.
Options can be passed as the second argument to the output method. Keep changes targeted: a style or dimension adjustment that improves one page can change its layout, so inspect the output rather than assuming the rendered version matches the live page exactly.
Check dimensions and browser limits on long pages
Before treating an image as full-page, compare the captured bounds with the content you intended to include. Scroll dimensions are a useful input, not proof that the library can render a canvas of any resulting size. Long pages with large images or wide content can exceed browser or device rendering limits and may yield blank or partial output without an obvious error.
Browser canvas limits vary by browser and platform and can change. The html2canvas FAQ gives rough guidance for canvas limits in its own context, but those figures are not verified dom-to-image thresholds; do not use them as a promised maximum for this library. Test representative pages in the actual browsers and devices you support.
- Check that the selected element contains the entire region you want, including content below the initial viewport.
- Inspect the downloaded image’s width and height, then visually check its top, bottom, and side edges.
- Try a smaller node or a smaller capture region if output is blank, clipped, or incomplete.
- Test pages with their real fonts, images, and styles; resource availability and browser behavior affect the result.
Why the image may differ from the page
It is a rendered representation, not a guaranteed browser photograph
DOM-rendered image libraries reconstruct an image from page information rather than capturing the browser display as a camera would. CSS support can vary between tools, and a rendered result should not be described as guaranteed pixel-perfect. In particular, html2canvas documents that it reconstructs a representation from DOM information and implements CSS properties individually; that is a caution about html2canvas specifically, not a statement of dom-to-image’s exact compatibility.

Cross-origin images and unavailable resources
Images and other resources may fail to load into a render, including when browser origin rules prevent access. The library’s imagePlaceholder option can provide fallback content for an image fetch failure. Do not transfer settings from another library: for example, useCORS is documented as an html2canvas option, not a dom-to-image option.
Dynamic content and page state
The capture reflects the DOM and resources available when the rendering runs. If content is still loading or changing, wait until the page is in the state you want before calling the method. For pages whose content depends on application state, make sure the chosen node and its rendered dimensions correspond to that state.
Troubleshooting incomplete or failed captures
| Symptom | Likely cause | What to try |
|---|---|---|
| The output stops before the bottom of the page. | The selected node or requested height does not include the full content, or the render has hit a browser or device limit. | Check the selected element’s scrollHeight, pass the intended height, and test a smaller region if the image remains incomplete. |
| The image is blank or only partly drawn. | The requested image may be too large for the environment, or required resources may not have rendered successfully. | Reduce the captured area and inspect the page’s images and other resources. Test on the target browser and device. |
| One or more images are missing. | An image fetch failed or browser origin rules restricted access. | Check that the resource is available to the page and try imagePlaceholder when a fallback is acceptable. |
| The output looks different from the live page. | The image is a DOM-based rendering and may not reproduce every browser-rendered detail. | Check the specific styles and resources involved, then compare the result in each supported browser. |
| The promise rejects and the download never starts. | The node was invalid, rendering failed, or a resource or browser error interrupted the operation. | Confirm that the selector returned an element, inspect the caught error in the console, and test with a smaller or simpler node to isolate the cause. |
When to use a browser screenshot instead
dom-to-image is an in-page option when you need to render a DOM node from JavaScript. If your requirement is to capture a page in a real browser, control browser state outside the page, or run captures server-side, a browser automation approach may fit better. The html2canvas FAQ points to browser-native screenshot APIs as a more reliable path for browser extensions and to Puppeteer or Playwright for server-side screenshots; those are recommendations from html2canvas documentation, not compatibility guarantees for dom-to-image.
Choose based on where capture runs, how faithfully it needs to reflect browser state, how cross-origin resources are handled, and how your workflow will manage very long pages. Whichever approach you use, validate the result for the actual site and runtime rather than assuming that “full-page” means unlimited dimensions.

FAQ
Can dom-to-image save a PDF?
The documented output methods include SVG, PNG, JPEG, Blob, and pixel data; they do not establish a PDF output method. For PDF output, use a capture workflow that explicitly supports PDF.
Can I exclude a navigation bar from the image?
Yes. Use the documented filter option to exclude a node and its descendants, or select a narrower node if the navigation is outside the region you need.
Does full-page capture mean the browser will scroll and stitch screenshots?
Not in the method described here. This approach renders a selected DOM node and requests dimensions for it; it is not a sequence of viewport screenshots stitched together.
